Crash is, simply put, a Dalek. His creation story is that of any other Dalek. He is obsessed with killing and enjoys the pain of others. He earned his name from the Dalek Supreme himself by crashing into starships and exterminating all on board. He looks like a standard Dalek but was experimented on in a distant solar system and now thinks like a civilized being. (Although he still has the Dalek trademark of hating and wanting to kill all things non-Dalek.) The beings that experimented on him gave him a word of advice before ditching him on Skaro: Never, ever question orders lest you give away your true identity. He can't wait for the day that he can exterminate the beings that gave him the burden of thought.
Attitude: Killing Machine, very anger
Quirks: Likes to kill and kill and kill and kill and kill and kill.
Weapons/Gadgets: Gunstick, manipulator, and the ability to elevate.
If this is terrible, it's either because I'm new to this or It's 2 in the morning.
