Yeah, I have no problem with selling out to Schick or hilariously gratuitous Doritos product placement, but I do hate crossovers when they're clearly different universes. Good Transformers crossovers include Spider-Man in Transformers #3 when it was part of the Marvel U, and likewise Circuit Breaker; Marissa Faireborn and Snake in the G1 cartoon; 'Ancient Relics' in Transformers/Action Force; Bumblebee becoming Goldbug in G.I. Joe and the Transformers, Megatron becoming G2ised in G.I. Joe, etc.

Transformers and Evangelion are distinctly different universes, and every time I think about Optimus Prime in Tokyo-3 I want to curl up into a foetal position or run away.
