ALRIGHT LISTEN UP. This is long as fuck, but it gives every current Beastboy’s personality, and just general behavior. Huge shout out to @silcatian for proof reading this, also for a bunch of really good headcanons for Towelboy, Hotboi, and Loverboy. Go check her out <3
Bomberboy - Beasttale
Height - 7’6”
Personality - Brash, cold, apathetic, overbearing, jealous, hot tempered, can swap into a cuddly safe skeleton within seconds, or just as easily switch to murder mode
Behavior - Tends to not care much, unless it’s about his mate. To whom he is overprotective. He cares for his friends, but doesn’t show it until he knows the timeline is safe. When it comes to his mate, he only wants the best. Which is just staying by him safely within his house. He requires so much attention. He’s also jealous as fuck, like a smile at a stranger will cause him to stew angrily all day. Good chance he’ll punish you for it. HEH HEH HEH. He doesn’t take kindly to his mate arguing, or wanting to do things without him. Which can cause him to snap. Sometimes he just yells and can’t control his actions. Other times he can harm his mate, possibly killing them. During his heat, he tends to hunt. Meaning humans, cats, dogs, whatever he can get his claws on. Which is why a strong bunker is a must. Unless you like all the neighborhood pets ending up in your bed. Also you know, the whole, he could literally tear you apart during his heat. Poor bab can’t help it. As for regular life. He will generally lay around and avoid doing more than he has to. Too much noise. When his mates dies, he will reap the soul, and eat the body.
Lovebun - Beasttale
Height - 14’
Personality - A huge sweetie pie, brave, confident, charismatic, cunning, optimistic, naive, brash, energetic, strong, and kind
Behavior - Very similar to Undertale Papyrus, Lovebun believes in everyone. Even if they try to kill him. He cares very heavily for his brother. He is ace. But does enjoy romance, even if he’s not good at it. He tries. When it comes to a significant other, he makes sure they’re comfortable and happy. He puts everyone before himself. He gets gifts to show his love, he doesn’t really know any other way to show it. So be prepared to get the same gift constantly. Getting everyone's approval is also high on his list, which can lead him to do things he doesn’t realize are wrong. He is very innocent and naïve. He didn’t know robbing that bank was bad, those guys said it would make him cool.
Cherryboy - Beastfell
Height - 8’9”
Personality - Brave, kind, apathetic, tends to be detached from relationships, and reserved
Behavior - He is slow to reveal his actual self. When first met, he seems hostile and all out aggressive. But that is simply a front. The underground is a harsh place, so you have to act tough. It becomes obvious that it’s a front the moment you meet his brother. When he gets a mate, it’s all about them. He’ll do things for them, get them gifts, make sure they never have to do anything. But the only problem is he bores easy. So if his mate can’t keep his attention, he just kinda drops them. Sometimes a human comes along, that can hold his interest. He’s not sure what it is about them. But good lord, he loves them. He wants to protect them. But he’s nowhere near Bomberboy levels of protection. Where Bomberboy would consider killing his mate to keep them safe. Cherryboy would react normally to whatever the situation was. He’s kind of a pacifist, tries to avoid fights, most of the time anyways. Every now and again he can just lose his shit and tear a building apart. He feels terrible afterwards. He could never harm his mate though. Not even during his heats. He can actually control himself side eyes Bomberboy. When his mate dies, he gives the body to the family, but reaps the soul.
Spike - Beastfell
Height - 13’10”
Personality - Brash, slight narcissist, naive, try hard, not as evil as he makes himself to be, huge whiner, reserved, and easily flustered
Behavior - He can be incredibly intimidating the first time you meet him. His height, scowl, and pointy appearance would scare the shit out of anyone. His voice is heavy and would scare you even more. But the second he flips his scarf and holds his hand for you to take. You know he’s not as mean as he makes himself seem. He would guide you around the puzzles. Yes he would make remarks about how much you’re a failure. But you can tell he doesn’t mean them. He even accidently compliments you during the puzzles. Getting to know Spike, means listening to him whine about wanting to be an actual part of the guard. Not just a stupid sentry that sits around. To become his mate is a process. Filled with paperwork. Which can just be bypassed with a simple peck on the cheek or a lot of compliments. Which will fluster him and cause him to walk off. Just shove the paperwork into a paper shredder and you’re good. Just tell him you didn’t want anyone else to know what your answers were. He’ll believe that. Spike doesn’t really show what he’s thinking in his body movement. He generally keeps his stoic, ‘I’m a bad guy’ stance. But for his mate, he tends to show small gestures. Like crouching to their level, hair pets, and wanting to hold hands. He just loves how small your hands are. Compliments are rare from him, but when you get them, you know they’re genuine.
Ripperboy - Beastswap
Height - 6’5”
Personality - Narcissistic as all hell, naive, brash, and manipulative
Behavior - Honestly this fucker is barely worth your time, he only cares about himself, how great he is, and how much better he is than you. He will spend his time belittling you, making you feel terrible. But that’s not to say there’s no good in him. He’s scared and doesn’t trust you to stay with him. So he pushes you away. That doesn’t mean what he does is okay. It’s super fucked up, like dude, chill. When he trusts you enough, the insults with slow, and eventually stop. You’ll notice when you fuck up, and he doesn’t make a comment. It’s actually surprising. Because what the fuck. Is he okay? When you ask him, he’ll just respond “Everyone makes mistakes. Well, everyone but me”. Eventually he’ll make small quiet comments about how great you are. That you’re almost as good as him. Those make you feel good. Again that does not excuse how shitty he is. Eventually claiming you as a mate means small gifts and compliments. Very quiet and discreet, no one can know. He loves cuddling and will require your attention a lot. He loves when you pet him, or talk about how great he is. Giving him genuine compliments, or being nice to his friends and family will fluster him. Also he is a part of the Royal guard, a feat that no Papyrus (he counts as one) has really accomplished.
Canine - Beastswap
Height - 18’
Personality - Hostile, hot tempered (way worse than Bomberboy. Impressive I know), and malicious
Behavior - Honestly I’d say avoid Canine at all costs if you’re human. He has a disdain for most of humanity. There are very, and I mean very, few humans he will interact with. Interact with and either try not to kill, or try to maim. Canine can’t control his emotions very well, and is generally stuck on hostile mode. He’s not afraid to tell anyone to fuck off, or to go fight them. Leading most of the Underground to stay the fuck out of his way. No one fucks with him, or his brother. If you somehow manage to catch him during his calm period, then you have a very high chance of befriending him. But the moment his smile goes to a scowl, just get the fuck out of there. Unless you like bits of you going everywhere. He’ll text you to know when he’s okay again. His calm moods generally last for only an hour or so. Then he’s back into unstable territory. Eventually you’ll be able to get a schedule down, recognize the pattern to his calmness. It’s three times a day. Morning, Afternoon, and Evening. Times vary. Texting is the only option when he’s unstable. Or another way to tell, is look for Ripperboy. Ripperboy tends to stick around Canine when he’s unstable, and goes away when he’s calm. Being his mate isn’t a safe option. He’s far too big, and too sharp. He’d tear you apart faster than Bomberboy. If his mate dies, which there’s a huge possibility of that, he just eats them. Forgets about the soul because he’s an ass.
Hotboi - Beastlust
Height - 7’8”
Personality - Kind, mischievous, deceitful (gotta keep his sexuality a secret), fatherly, secretive, and brotherly
Behavior - Hotboi is actually completely ace. He tends to keep that quiet, as it’s frowned upon. Though he doesn’t mind helping someone out, as long as it’s just his hands or tongue. He loves to play small pranks, but they’re always kind hearted. He’s easy enough to talk to and getting to know him isn’t that hard. He’s an open book so to speak. When he gets a mate, he will love the fuck out of them. Gets them gifts that he knows they’ll like and always has time for them. He loves cuddling and just being near his mate makes him happy. He wants kids like you wouldn’t believe. When he feels him and his mate are ready, he’ll bring up the idea of adoption. During his heat, he just hangs out in a bunker he made himself. As Alphys wouldn’t make one for him, not understanding why he wouldn’t just go get a heat buddy. When his mate dies, he gives the body and soul back to the family.
Acid - Beastlust
Height - 14’4”
Personality - Brave, brash, cocky, charismatic, cunning, energetic, and manipulative
Behavior - He craves an actual standing relationship, which are hard to find Underground. Monsters just fuck, rarely make love. He knows just what to say to get someone to follow him around. So him charming someone into liking him isn’t that hard. It’s just a matter of getting them to actual like him. As humans just see monsters as horny and generally just get with them to fuck.
Towelboy - Dancebeast
Height - 7’8”
Personality - Cocky, slightly narcissistic, mischievous, hot headed, loving, easily flustered, and energetic
Behavior - He is incredibly smug, and full of himself. Which tends to come out more when he’s trying to impress a possible future mate. He may be smug, but affection flusters the hell out of him. Just holding hands will cause him to blush. He has different dances for his different moods. Which he only shows to mates, potential mates, or to genocidal 8 year olds. Since dancing is important in this universe, Towelboy will want his mate to dance with him. If they say they can’t, he will gladly teach them. He has the patience to do so. Dancing with your mate is seen as intimate. Since emotions are shown through dancing, he is one of the less life threatening Beastboys. He also has far more energy than most. He is picky about picking his mate, after all he’s putting in the effort to show off. He holds heavy emotional attachments to his mates. So when they die, he eats the body, and reaps the soul.
Behavior - He is the sweetest of all of the Beastboys. Don’t let that fool you, as he can become far more dangerous if he gets into a mood. He is actively trying to stop himself from relying on humans for food. But he does like providing for his mate. So he still ends up killing a few humans, but only those who aren’t considered good humans. Though he now tries to aim more for deer or other forest animals instead of human people. He forms incredibly deep attachments, and accidently killing his mate can mess him up for a long period of time. It could take months or even years before he’d go about getting another mate. He warns his mates about the possible danger that comes with being mated to him. He will try normal means to gain a mate, but if that doesn’t work. Abduction is always an option. He has a house in the middle of fucking nowhere. So trying to flee won’t work. He loves to cuddle, and will praise his mate for everything. Even if it’s something small, like getting out of bed. He is all about slow and gentle sex. If his mate were to become pregnant then he becomes more animalistic. During the second trimester, he won't let his mate leave the house without him and he will barely talk. Third trimester and he won't let them leave the house at all and he would only communicate in growls, chirps, and purrs. If his mate ever gets angry and possibly violent, he will literally fuck the anger out of them. He is constantly worried about hurting his mate, and possibly triggering the urge to consume them. So he wears puffier clothes, and tries to keep his pointier bits away from their soft flesh. The rounder his mate, the better. It shows that he is providing for them well. He also loves the extra softness. Which he has an affinity for soft things. So if he’s in one of his moods, just wrap up in something soft to fend off death. His mate is always ahead of himself, meaning he can forget to eat or do something. If his mate get their period, he will send them off to the humans. Being near monsters while bleeding will lead to death. During his heat he will get a heat buddy, and lock himself in his bunker. If he doesn’t fuck, he’ll want to eat. He is actually quite thin compared to other Beastboys. His bones are thin due to not eating properly and losing mass. So he stuffs his jacket and pants to make himself appear bigger. He stuffs it with human hair. Fun. Though above ground has constant food, so he gets stronger thicker bones over time. Loverboy likes to read to his mate, he can’t speak the clearest though. But his mate appreciates the effort. When his mate dies, he will give the body back to the family, but keep the soul. He won’t reap it, just protect it until it fades. Unless his mate specifies otherwise.
Perdio - Horrorbeast
Height - 22’
Personality - Oblivious, naive, hard headed, and strong
Behavior - Perdio, doesn’t really do romance. Though every now and again he’ll try. Being human and dating him isn’t really a sound life choice. He has the hardest time coping with the fact that he doesn’t have to eat humans any more. If another monster needed food, Perdio would happily offer your life to the monster. If he gets hungry, he will just straight up take flesh from his mate. Or from Loverboys, if they’re around. Which is why Loverboy tends to keep his human near him, and nowhere near his brother. He will tend to use his mate to test is food or puzzles on. Both will more than likely lead to death. He’s sweet...ish. He tries to say nice things, but they tend to just creep humans out. It’s completely unintentional.
Mi verso es para aquel que perdió el rumbo,
Para el que huye de este mundo de caretas.
Pa' los poetas que parecen vagabundos,
Y pa' aquellos que llegaron los segundos a la meta
