Again, I'm really not a Ridley fan but that post sums up the many reasons I'm inclined to think the purple pterodactyl is in. If Ridley isn't in then ~shrug~. If Ridley is in then... ~shrug~
I guess it'd at least be an interesting addition, though I suspect they'd have to make the wings have no collision as that's where the majority of size issues come from regarding platform heights and whatnot for it.
Random tangeant: How 'big' of a character is Metaknight for Kirby fans? How many people knew about the character before his Brawl inclusion? Having Halberd in as a stage seems to indicate the winged-one's return but I'm curious how many people are interested in the character beyond his broken-tier status in the last entry :3
