Wait. How do Squirtle and Ivysaur not have enough star power to merit their own slots but: Ness, Lucas, Marth, Ike, Roy, Jigglypuff, Pichu, Ice Climbers, Palutena, ROB, Pit, Shiek and half a dozen other lesser known characters do? That doesn't make any sense.
It makes perfect sense.
First off Lucas, according to the sal leak, is probably gonna be cut, and was only in from brawl, so he doesn't have the popularity either. Pichu was cut, so this doesn't even make sense, re-read your posts.
Ness, Falcon, and Jigglypuff have been in since smash 64. Any of those vets have enough star power from longevity in the series alone to merit inclusion. Don't expect them to be cut.
Marth? Really? You include the main fire emblem lord, ever, to not have star power?
Pit? Ness? These characters are the main characters from their respective franchises. You obviously have some strong bias against other Nintendo series'.
See, here's the problem. We're getting close to 1000 pokemon. Give it one or two more generations, we'll be there. Smash is gonna have, if we're lucky, about 50 characters. Most popular roster predictions give 5 or 6 of those slots to pokemon. That's 1/10 of the cast.
So how do you choose 5 out of 700 odd pokemon? Popularity, and promotion.
Pikachu is the face of the series. He is just as important to smash as Ness, Marth, and Pit, the faces of their series. He's in.
Jigglypuff has been in since mash 64. She may have declined in popularity, but I don't think Sakurai is going to cut her for that.
Lucario is one of the most popular of the more recent pokemon, basically the face of Gen 4. This is evident from the mega evolution it received, the movie it got, and its role in Pokemon X/Y.
Charizard is one of the most popular pokemon in existence, being one of the only 2 pokemon that got 2 Mega evolutions, appearing in multiple movies, and making a comeback as a starter again in X/Y
Greninja is a starter from the brand new pokemon games, which Sakurai felt a need to represent the most current generation of pokemon in smash. After all, lucario is out of date now
And we have an argument for Mewtwo coming back - popularity, the only other pokemon with 2 megas, ect. Not confirmed, but definitely has a shot.
Squirtle and Ivysaur have nothing on any of those pokemon. The problem with their ability to get back on the roster is high barrier of entry. It's the same reason we aren't going to have Toad, Bowser Jr, or paper mario this time around. They all have merits, sure, but you can only have so many characters from one series before it is completely over-represented.
Squirtle and Ivysaur were extremely lucky in brawl, they managed to sneak in under Charizards cover, as transformations. But with transformations cut, they won't be seeing playability in smash again, unless they get lucky with DLC.
(dont get me wrong, I'd love for that to happen. I like these characters, and I hate cuts. I'm just being down to earth, and you obviously are on cloud 9, or somewhere very far from reality)
