I’ve seen Junkrat compared to the creepy man that cuts hair in Courage the Cowardly Dog and a few other characters. But I’ve personally haven’t seen any comparison to Rattrap from Beast Wars.
Hear me out.
1) Both are based on rats
2) Rattrap’s first color scheme is copper, silver, brown and a couple of different colors, very similar to Junkrat’s
3) Rattrap’s second form latter in the series has wheels and in robot form the tires are on his back.
4) Rattrap’s original concept was as a disabled character, hence his ‘brain cap’ designs, but due to the tech the animators had and someone higher up they couldn’t go too far with that idea.
5) They’re both demolition experts!
6) Rattap’s best friends/frienimes are very tall/big, Dinobot and Rhinox. Junkrat’s best friend (and/or bodyguard) is Roadhog.
