After watching this Awesome trailer I noticed that the alloy team is shown fighting and what else the red one uses a KNEE at 3:44 exactly! So this proves even more that he is based off good old captain falcon and will hopefully be returning with his incredible kneee .
Another thing about the alloys this also proves green to be kirby he does his fsmash. Blue does what seems to be Zelda's ground neutral and floats like her. Yellow still seems like mario but all he does is his neutral air and some sort of taunt or mario's new dair not sure. DISCUSS!!
