Eternal phoenix Fire
Smash Hero
Dark=/=Horror. Majora's Mask is dark. I wouldn't consider that horror. I honestly can't see how you think Metroid is a horror series. Only the Prime games had "scary" stuff in them and even then it was one time in each game.
Ridley is an important part of Nintendo history as well. That's why he's in EVERY smash bros game somehow. Ganon and Bowser can't say that.
Ridley should be the final boss at one point. But that doesn't really change my point. Imagine a Ridley final boss on top of some sort of tower. Sounds like it would be fun!
Ganondorf/Ganon does not actually appear in the Zelda series all that much. He's absent in about half of them. Ridley has appeared in the majority of Metroid games.
Zero Mission technically retconned the original story so....I'll just take off the original instead.
If by being in every smash Bros game you mean lingering in the background somewhere or being seen briefly? Bowser and Ganon have been playable have been playable in the last 2, and Bowser is playable in the 3rd. Ridley's greatest feats were of him being a boss in subspace, which seems to be his greatest quality.
I respect Ridley too, and he should have been a Final Boss, but how much is even left of this guy? I mean every game incarnation he's just more and more jacked up, it's like fighting the terminator. But in some games he appears normal without the armor, which is one thing that kills me; the inconsistency of his appearance. Is he half machine, organic, all machine or what?
I have nothing against Ridley, he just has some obstacles going against him as far as him being a functioning playable character. And even if they did re size him, I really wouldn't want them too. It would look like you're fighting against a purple mosquito.
