The day Smash bros add Babies as playable character will be the day I give up hope in the series as a whole.
I mean, that's a past role, not a current one.
Even then, Kamek is clearly shown to be a separate character from generic Magikoopas even in Japan, where their names are the same. He has his own characterization and motives, particularly in the Yoshi franchise, where this particular Magikoopa, called Kamek here, is essentially Bowser's foster parent.
This doesn't discredit him any more than having multiple Pikachu discredits the Pikachu shown in Smash.
Maybe so. But I just don't think it's likely. Even Poochy seems more plausible to me. Besides that, we already have 2 Mario universe villains. Bowser Jr. could very well stand in for Baby Bowser in concept. I also really doubt Yoshi's Island will get a second character ever, much like F-Zero.
Also while we're at it... Hype levels just for fun:
Ridley: Hype: 75%
-Despite being a critic of Ridley, he'd hype me a great deal. Would seem like a closure of sorts for many people, and I'd surely try him out for fun.
Simon: Hype: 35%
-Played a little Castlevania. Simon is a cool dude, interessting playstyle. Rather not have too many 3rd party characters however.
Wolf: Hype: 85%
-Most deserving veteran to return easily. Didn't play him all too much in Brawl, but missed him greatly in Smash 4. Would've rather have Krystal however, I'll just be honest about that.
King K. Rool: Hype: 100%
-A fat and bloated 100% however. Most wanted character easily. Would also signify his return to DKC, which is what I always wanted even more than having him in Smash. Gives Smash a much needed super heavy weight newcomer, and finally another DKC character after Diddy's late arrival in Brawl.
Dixie Kong: Hype: 100%
-Everyone thought she was a shoe-in with Smash 4. Missed her ENOURMOUSLY therefore in Smash 4. Great character, DKC is still my favorite franchise ever, and she's easily as deserving as King K.Rool.
Sora: Hype: 0%
-I really don't want him in honestly. I get the appeal for the crossover effect, sort of merging Nintendo with Disney, but I simply don't like the character.
Geno/Mallow: Hype: 50%
-Geno is cool, but never used Mallow much in Super Mario RPG. Granted I didn't even finish that game. But still. Why would they be a tag team again? Seems kinda forced.
Chorus Kids: Hype: 25%
-Guess it'd be cool as a concept. Yet am not familiar with Rhytym Heaven and wouldn't know why they would be chosen in the first place.
Porky: Hype: 85%
-Am a big MOTHER fan. Porky would be hilarious.
Medusa: Hype: 30%
-She's not even the main villain? Seems forced, and Sakurai's Kid Icarus bias would show up again. Yes, it would work with a Heroes vs Villains concept, but still... Palutena semi-clone maybe? I'd hope so at least.
Mimikyu: Hype: 65%
-Mimikyute. Interessting design, backstory, and abilities. Am totally down for it.
Elma: Hype: 55%
-Despite never having played the game, Elma has a cool design and learned a great deal of her potential playstyle. Seems overpowered however, kinda a mix between Zero Suit Samus and Bayonetta without the additional effects and stuff.
Snake: Hype: 60%
-He was fun to fight against in Brawl. Missed him more than expected in Smash 4, especially since I think he's cooler than all other 3rd party characters.
Ice Climbers: Hype: 5%
-Yay the broken grab gimmick duo is back
5% only for veteran status. Might be more hyped if they are actually fixed... But I have my extreme doubt. Easily the most reasonable cut of a unique character concept in Smash ever.
Goroh: Hype: 25%
-I once wanted him. Now F-Zero is kinda dead. But hey, so is MOTHER. In terms of samurai-like characters, there's far more cooler characters to work with. For example Impa, Hyrule Warriors style, and Lyn.
Takamaru: Hype: 55%
-Anticipated his arrival in Smash 4. He wasn't included. I wasn't even all too bothered honestly. Seems like a well deserved addition however.
