Seeing as how Capcom is probably never going to release another MML game, there probably won't be any room for ProtoMan... DAMN YOU CAPCOM!!!!

I swear, if they don't release a new MML game within the next generation of consoles, I will take a katana and chop them all in half. Personally. In person. While I'm there myself.
They are evil- they make a cliff-hanger ending and never bother to make a sequel?

i personally think its a good idea and since megaman goes helmetless most of the time that means protoman would look pretty cool without a helmet and even more mysterious:P

Protoman? I wouldn't count on it. A Legends version of Rush as a lost reeverbot puppy that can transform into vehicles would fit in well story wise. I could also see Cossack and Kalinka making a cameo like Wily did as the boat master in Legends 1. We've seen imagery of Beat in Legends 2 as those bird bot ships, a metaphor of Gamma in Tron Bonne.

If a Legends 3 were ever created, we would probably see reeverbot references to characters like Plantman, Knightman, Stoneman, etc.
