Since the one Ridley who's in Smash4 as a stage-boss is just a clone, and one of many Ridleys (and not even a popular one, by the way), i don't see how Ridley as a playable character "can't happen".
Yeah, Sakurai keeps saying "he's too big", but so is Bowser usually. And Olimar would be too small.
-Hm? Bowser's height changes in the Mario games? So does Ridley in the Metroid games.
But oh well. Maybe voting for him will still help, Nintendo might remember our votes for future Smash games.
...but i do agree on one thing.
If it's not Ridley, i don't see any other Metroid character happening.
No one is as popular, as important to the franchise, and as iconic as Ridley. (...aside from Samus herself of course)
The Prime Hunters were forgettable (and only in one game), so were the bounty hunters from Metroid Prime 3.
I had to look up Sylux in the Metroid Wikia to remember who he even was.
NONE of them deserve a real spot in the smash roster.
And we REALLY don't need more clone character such as Dark Samus or SA-X.
Other M has what? Little Birdy? Anthony Higgs? Whiny scared Samus?
Honestly, i don't really see any other Metroid character standing a chance.
The ones close to Ridley would be Mother Brain (not seeing her happen), the baby Metroid, and maybe Kraid who's 4-5 times the size of Ridley.
I want ridley over everything else, but since hes a boss, i DONT want two Ridleys in the game. I also dont want another Samus.
We have 2 Marios & 2 Links. How is one playable Ridley, and one Boss Ridley a problem? O__o
Heck, Other M Ridley is his own character, just how Dark Pit, and Lucina are their own.
The playable Ridley could be the original one (Metroid/Zero Mission/Prime Trilogy/Super Metroid).
