Not these guys. These guys are just new.
The fellows below are the newly announced "Mega" forms of already well known Pokemans. These Pokemon can only be gotten when you MEGA EVOLVE them. Their names stay the same and just get "Mega" slapped on the front. Apparently going Mega is the same as going Super Saiyan. More power and more hair, baby. I honestly can't decide if the whole thing is super lame or super awesome.
Could we see this new form of Lucario or Mewtwo in Smash 4? And if Blaziken gets a Mega form do the other starter final forms get it as well? I want MegaBlastoise. NOW.
