>>11195711>a robot with spiky hair would look ridiculousWhat makes you think it needs hair at all? Naruto has spiky hair, but his crossover representation just gives him a Cheetor-esque helmet. No reason they couldn't do something similar.
>>11195715Yu-Gi-Oh is not an American card game. Well, the card part was originally American, but the actual story was from Japan and was very different. Regardless, using BEWD for a potential crossover is a no-brainer - she's easily recognizable, there's a clear concept of who she'd turn into, and she'd be an easy TM2 Megatron retool if they didn't feel like giving her a dedicated mold.
