so, this is how it goes
i will make two rankings, since the mask is part of the ''unique'' chars in the feats aspect, there is the crossover version (which is even stronger and more hax) and there is the canon version (which is still strong, but not at that level)
so
it goes like this:
rom (full power) > the mask (crossover edition, his hax is too broken) > gladiator (with his high end feats too) > cyborg supes > lobo
and the other is
rom (full power) > gladiator > cyborg supes > lobo > the mask (canon version, he is the weakest and all, but none of them can fully erase him, since he needs high level erasing techs, to fully erase him, but they can still k.o him obv = stills counts as a loss)
not to mention, even comic canon mask can still solo yeehaw, like a cui, lmao, his hax is still broken
