>>48218579Mixed up the Ultimate/Perfect order there. Looks like Omedamon is a Warp Evolution though (straight from Adult to Ultimate).
But basically, a crossover would probably be something like
>Baby I: ?>Baby II: Charmander>Child: Charmeleon>Adult: Charizard>Perfect: Mega Charizard X/Y>Ultimate: ExamonYou could conceivably make Megas into mode changes with no level increase, which would also allow you to make Charizard evolve into MetalGreymon.
