Throughout my writing process I've been referring to the original Decepticons I introduced as the 'Nemesis Crew'. It just kinda stuck, I guess. I kinda think about it like how the main Autobots in Transformers Prime are called 'Team Prime'. I'll admit that I've taken some inspiration from Prime, but I'm also trying to find my own footing too. Anyway, back to the main focus, which was listing the Nemesis Crew. Quick note is that this mentions original and basic characterization and that there are more complex arcs and personalities. Anyway, here we go:
Megatron, Leader of the Decepticons and commander of the Nemesis. White body, gray limbs, blue wings attached to back, cannons attached to shoulder, Cybertronian combat jet alt mode. Megatron is a wise, stoic, and experienced leader, but is also aloof and somber, though not uncaring. Though seeming intimidating, he can be compassionate and poetic.
Starscream, Decepticon Second in Command. White, black, and red Seeker frame, swords attached to wings. Starscream is intelligent and a strong fighter, but he struggles with a lack of self confidence and an anxiety disorder, though don't mistake these issues for weakness, for he will still fight to the death for the Decepticon Cause and fellow Decepticons.
Soundwave, Communications Officer. Dark blue and white, yellow visor, face half covered by battle mask. Soundwave is laid back, a little unorganized, a music fanatic (Cybertronian and Earth), but also an excellent communications officer. He also has an arsenal of minicons, made up of Rumble, Frenzy, Ravage, Laserbeak, Buzzsaw, and Ratbat. Despite his laid back attitude, Soundwave is well aware of the tragedy of war, but seems to try to forget whenever possible.
Shockwave, engineer. Red and black, tall thin body, one blue eye instead of a face. (I would like to clarify that Shockwave is modeled after TFA Shockwave, but is red and black, the previous Decepticons are modeled after their Shattered Glass versions). Shockwave was forced to undergo empurata, when the Autobots decided he would be useful to them. The Decepticons later found him and rescued him, but he was still damaged physically and emotionally, hence why he doesn't fight. Despite this, he works hard to be useful to the Decepticons and create inventions to further their efforts against the Autobots.
Knockout, Chief Medical Officer. Aquamarine, car alt mode, on the smaller side, very scratched up and dented. Knockout is a medic with limited fighting skills, but has an electric staff (for awhile I jokingly referred to it as a 'Cybertronian cattle prod') to defend himself. He can be kind, awkward, but also serious when it comes to his job. While he doesn't seem to care for his appearance or self care, he does an excellent job of caring for his patients and conjunx.
Breakdown, nurse. Blue and gray, orange face. (Confession: I like his appearance so I kept it the same). Breakdown was once a great warrior, but due to an event he dislikes to talk about, he now suffers from PTSD and has since decided to dedicate his life to helping injured Decepticons, along with his conjunx, Knockout. He can be soft spoken, solemn, easy to miss despite his size, but also has great bedside (berthside?) manner.
Thunderblast, soldier. Purple and yellow, strange wing-like attachments, feminine body, speed boat alt mode. (I don't know how many people know about her, she's a female Decepticon from the Cybertron cartoon, the final entry in the Unicron Trilogy. She essentially looks the same as normal, but with blue eyes and the yellow and purple of her design switched). Thunderblast is a Decepticon soldier, with a passion for history and recording it. She can be somewhat rude, flaunting her intellect, and is not particularly well liked. Though her tendency to rely on no one but herself and her unwillingness to open up stems from her past.
Skywarp and Thundercracker, seekers. Thundercracker is a dark blue and white seeker frame, while Skywarp is purple and white. (I forgot they had Shattered Glass versions when I started, so I ended up creating my own versions. I'll admit I did not stick to the actual Shattered Glass stories at all). Despite being veterans of the war, they're not above being somewhat immature. They tend to joke a lot and tend recieve discipline for their actions. However, they are inseparable, and very loyal to Starscream, as the three are in a trine.
