While there are stupid clones (Pichu and Dr. Mario, even though I loved the Dr.), some clones do make sense. Toon link (who I think should be reverted back to young link simply because I'd like him better in HD) is a faster and more lightweight version of link, with better recovery. His boomerang doesn't pick up items, but unlike Link's, it hurts you on the way back, so you can throw it, grab someone, and damage them while you damage them. As well, his dair makes him go very quickly to the ground (like Sonic), while Link has no speed difference (like Lucas, who was also a good clone).
There are, as well, characters who I believe should never be cloned simply because the moves they have should be retained to that character's fighting style. In other words, I do not think they should make Bowser Jr., who would be a faster, light clone of bowser, simply because I fell that Bowsers moves have a "I'm a heavyweight" ring to it. Would you like to see a mini Bowser blowing fire, and grabbing you and landing you on the ground on his belly? No.
However, I would like to see a Bowser Jr. if they changed up his moves (similar to how Luigi and Mario are very different, or maybe how Lucas and Ness are very different even though similar). It would be nice to see a Bowser Jr. with different special moves. However, I don't think that would happen because the moves would have to be completely different from Bowser's for that to happen, and if they make it dissimilar to Bowser's, it would probably be similar to someone else's, thus also decreasing his popularity (i.e. if instead you made Bowser Jr.'s neutral special a charge-up-then-shoot fireball, which is unlike Bowser's, people may say, "He's copying Samus and Lucario.").
Anyway, with that said, here are my 5 people who should be removed (the order means nothing. Also, sorry I couldn't think of five):
1. Falco
2 heroes and a villain, as said before, is too much if they are all the same. Get rid of Falco and make Wolf's blaster a little faster. Done. As for the whole down special, I never like the "kick the reflector" idea. Also, Wolf and Fox look cooler, and Falco doesn't meet the standards his fellow Starfox Series players have created.
2. Pichu
No different from Pikachu. Even though the Toon Link/Link separation is a good idea, Pichu was nearly the same as Pikachu, so there was nearly no difference.
3. Lucario
I would be happier if they simply completely changed Mewtwo. I don't know why, but I'd rather have Mewtwo than Lucario simply because Lucario, in his movie, was good. However, Mewtwo sort of have this little 'epic' vibe to his power. I'm alone on this one, but I'm fine with that.
4. Roy
Like the Bowser Jr. and Bowser "I'm a heavyweight" argument, I think the moves Marth has should be retained to a fast lightweight. However, Ike was an extremely good idea.
Characters to be changed:
Wolf. Please see the Falco spot above.
Ganondorf. I don't mind that they made a clone of Captain Falcon: I'm fine with a heavier version of him. But to me, they are too similar to be from different games. I think they should change his down special a little bit, to more fit the fact that he is the king of evil who wants to kidnap Zelda, not the king of evil from medieval times driving a race car.
Zero Suit Samus. The thing I want changed is her side special, and her up special. Her up special should go diagonally, and her side be should be different, or else she would be too plain. Maybe a lunge-kick, or a charge-shot that damages more and charges more, like Samus's neutral special.
Other characters of notice:
Dr. Mario. I know he's a joke, but I would like him back. I think he should have replaced Jigglypuff in being one of the three who you unlock at the end of SSE, and Jiggly should have had some sort of contribution.
Diddy Kong. I know I suck with him, but you do have to admit that his neutral special does very little damage to be useful, and his down special just sucks. I do encourage people to correct me and tell me better ways to use him; I would welcome that and use those techniques. Thank-you in advance.
EDIT: Disregard the Diddy Kong notice. It's just me.
King Dedede. His neutral special should do more damage, considering the fact that they completely sacrificed the whole swallowing idea (which was a good thing, don't take that the wrong way).
Sorry if my post was a little long.
EDIT:
I hear that. I try to abide by that concept... but the sheer amount of immaturity by overly defensive fans makes it hard to follow it (the infamous Lucario-Mewtwo debate, for example, both of whom I supported from the get-go... now with the former's reputation is slowly being eaten away thanks to his fanbase).
In any case, it's hard to come up with ANYone who shouldn't have been in the Smash Bros. series... They all had their time in the limelight for a reason (yes, even Pichu had popularity at one point, and made for the only decent 2nd Generation representative).
I try to enjoy all the characters, so it's kind of hard to think of who should NEVER have been in. Quite frankly, I'm glad all the ones that have been in have been in. Introduced me to more variety, something I *seriously* lacked.
You're right. It is very hard to find a character to remove because they are all unique, both the fighter's styles
and the player's styles. I take back the Mewtwo v. Lucario think I said, they should both be in.
