Ness and Lucas have NO attack PSI. Besides PSI Special (and Love for Lucas I guess which is his Up Smash) they only have defence and other. How can you draw a moveset from that?
Also, Toon Link is simple: He's Link. It only makes sence that he has the same moveset. I've explained Ganondorf numerous times.
Simple, by thinking outside the box. Here's an updated version of a special moveset for both of them.
Ness:
B: PK Flash
Same as before, but it should explode when time is up like in Melee
Side B: PK Rockin'
Same as the PK Fire Ness has used this whole time. Except, Ness shoots a ball of a bunch of shapes, but it still goes down in a pillar.
Down B: PK Paralysis
Works exactly like Zamus' Down Smash A except it the range is a Ness-width longer.
Up B: PK Teleport
Ness opens a worm hole underneath and disappears. Then, a worm hole opens facing the direction chosen by the player and Ness flies out of it. Anyone hit by Ness while he flies out will suffer an attack like PK Thunder 2.
Final Smash: PK Rockin' Omega
Ness makes a guitar out of PSI and starts playing either Pollyanna, Bein' Friends, Pokey Means Business, or the Hippie Battle Theme (which one doesn't matter, it's an easter egg). While playing, various shapes fly out of the guitar and hit anyone close enough.
Lucas:
B: Salt Water Gun
Takes out a water gun that is automatically charged and shoots it for knockback and some damage. Note, the gun recharges on its own over time.
Side B: PK Love
Shoots the attack like he does PK Fire and has the same knockback.
Down B: PK Counter
Lucas casts a protective barrier around him that acts like a mini Franklin Badge. Lucas can only have three barriers. at a time. Like R.O.B.'s Up B, this takes a while to charge completely after use.
Up B: Hinawa's Pigeons
The spirit of Lucas' mother takes the form of three pigeons that hold onto Lucas. These pigeons will pick Lucas up and Lucas can move side to side while rising.
Final Smash: PK Love Omega
Lucas creates a giant ball of PK Love and tosses it out in front of him. The attack can go through any stage and inflicts enough damage to kill.
See not too hard.
As for Toon Link, he may still be Link, but he is only ONE of the Links in the Zelda series. Therefore, he can still be his own character.
