There's no need to prove anything to you dude. You don't like them, then don't use them. Problem solved.
I agree a lot of them were cloned.
WARNING: SPOILERS concerning Final Smashes Below!
..You've been warned!
Spoiler Alert!samus/lucario:samus has a thicker stationary death ray compared to lucario's smaller mobile one.
link/toon link:same damned thing only one is cell shaded
fox/wolf/falco: same character IMHO different smashes and variations on reflectors and blaster properties but other than that it's just fox with a new skin to me. (and nothing will ever change my opinion so don't bother arguing)
Bowser can also be lumped in with the fox crew but his final smash lacks fire breath to substitute the tank cannon
lucas/ness: same thing different angles (one falls vertically the other falls in a fan-shape)
Dedede/Pitt:Both summon mobs of minions to attack you ones aerial the other land based
There are a lot of great ideas implemented in the final smashes but alot of them were very uninspired in my opinion. Just like the clone characters of melee, we have cloned final smashes in Brawl.
Although with subtle differences; just enough for someone to argue that they are original enough to be considered unique.
