Quasar: squad leader, trying to keep his brothers in line (and half-failing). Used to be a bit of a troublemaker before he got placed into the squad leader role and straightened out VERY quickly to make sure all of them didn't cause some intergalactic incident.
Azimuth: slicer, though he's also trained as a sniper and is an absolute crack shot when needed. Watches everything, a math geek. Tells everything he sees to Quasar and is a shit liar, so everyone calls him a snitch semi-regularly. Quasar encorages it because he knows his squad is full of insane people. Nicknamed Azzy
Perihelion: Demolitions expert. Probably had brain and hearing damage, and likes heat a little bit too much. Hands are covered in (minor) burns. Probably an arsonist whenever Quasar isn't looking. Hates being called Peri, only tolerates it when it's his squad doing it. Draws mindless circles when he's bored- actually quite a good artist, just doesn't get to draw often / thinks its stupid and keeps it under wraps. Is the one who painted Azzy's armour.
Melothesia (Mellow): Medic, generally chill and normal until he realises someone will listen to him yap and then he's talking for 100 hours about various movies and medical dramas he's watched. Also likely has no shame and is very vocal about how interesting the insides of some species are and how he wants to dissect things. He is lucky to not cause an intergalactic incident with how he talks sometimes. Because he's mostly chill, people accidentally think his name is Mellow, as that's what his squadmates shortens his name to. He IS NOT a medic cause he wants to help people, he's a medic because he is fascinated by biology. Would probably make bioweapons for fun without Quasar to keep an eye on him.
