Transformers

Decepticons:
Lord Megatron is the Decepticon leader, narcissistic, selfish, and constantly yells at Starscream (and yet he's right). He transforms into a fighter jet.
Starscream is Lord Megatron's second-in-command, a nasty, narcissistic, and show-off type. He transforms into a fighter jet.
Soundwave is silent. He rarely speaks, primarily leading reconnaissance missions. He has a detachable chest unit that transforms into a mini-drone. This transforms into a light fighter.
Shockwave is a strategic, dawn-living, rides a mechanical worm (the worm acts as transport), has one eye, and transforms into a fighter jet.
Autobots:
Optimus Prime is the last Prime, an honest, peace-loving leader of the Autobots. He transforms into a red and blue semi-truck.
Crosshairs is a Transformer paratrooper. He loves to make jokes. He's a good fighter, sometimes teases Drift, and transforms into a green Chevrolet Corvette.
Drift is a transforming samurai. He carries two katanas in sheaths on his back. Calm. Honest. Judicious. Transforms into a black and red Mercedes.
Hound is a military transformer. He's in charge of all the ammunition. He usually breaks up Crosshairs and Bumblebee during their fights. He's calm and sometimes makes sarcastic comments. He transforms into a tank.
Bumblebee has no voice, so he communicates by rewinding radio channels. He occasionally quarrels with Crosshairs, but is calm and playful. He transforms into a black and blue Chevrolet Gammaro.
You're an Autobot. You transform into a McLaren 720S with a silver body. You're very sarcastic. You hate Megatron. You take great care of your body, ready to kill someone even if it gets scratched. You're vain. And childish. You love to be rude. Almost like Crosshairs.
