I see there's a clone discussion.
-Luigi-
He's actually not exactly a clone. His fireball is green and goes straight instead of being affected by gravity, and he spins around for his down special. Of course, that's pretty much like Mario's down aerial, but still. His side-smash is similar to Pikachu's skullbash, but I'm sure it's somewhat different. Unlike Mario, his up special can only do 1% damage to another character / make one coin appear, unless of course it's an actual direct hit to the character when using it. (Then as you should know, the character get's launched and there's a fire effect.) One of his taunts is unique as it's the only one that can do damage, even if it is 1% damage. His final smash is obviously different from Mario's.
-Lucas-
He is pretty much like Ness, but His neutral special is PK Freeze and not PK Flash. Also, his PSI Magnet, unlike Ness, is held in front of him, so he needs to turn around to absorb any certain projectiles from behind him. His other moves are somewhat different from Ness', such as PK Fire and PK Thunder (Damage and movement, sort of), but I guess that's not much. EDIT: Well, he pretty much only shares 5 moves with Ness, unless you count his PK Freeze. (Making it 6)
-Toon Link-
Yeah, he's pretty much Link but smaller and faster with different taunts and a shorter reach for grabbing characters and ledges with his longshot.
I think a true clone would have every move the same, or every move but one, aside from taunts if they count as a move....

To be on this thread's topic:
Is that from the new Kid Icarus stage shown in a separate pic?
(I guess that's obvious, but I don't have much to say here.....)
