I actually have a moveset for his specials and Final Smash, so I guess I should just put them down here:
Up Special Move: Move
A large, white glove appears below Isaac, and slowly pushes him upwards.
Down Special Move: Set Dijinn
A tiny dijinn jumps out of his sword, and another one jumps in as that squchie sound from the games plays when you are just wondering and a dijinn sets itself. The move is something of a transformation, though Isaac's A moves are basicly unchanged, except for elemental differnces. The order is always Venus->Mars->Jupiter->Mercury->Venus.
Standard Special Move (Venus): Grand Gaia
Isaac begins to charge his attack, which sends out a wave of rocks, changing in size depending on how long you charge it.
Side Special Move (Venus): Odyssy(Spelled it wrong, I know)
Isaac shoots a small, sword-shaped ray in front of himself. If it hits, two small swods and a giant sword impale the enemy.
Standard Special Move (Mars): Searing Beam
Isaac Charges this move as well. At full power, it can go throgh enemies, instead of just stopping at the first one.
Side Special Move (Mars): Liquifier
Isaac throws a small fireball, which, upon hitting an enemy, explodes into a raging inferno.
Standard Special Move (Jupiter): Thunder Mine
Isaac throws a ball lighning at the foe, which has a weak homing abilty.
Side Special Move (Jupiter): Tempest
Isaac Summons three medium-sized torndos, which roam around the platform the first land on (ala a red shell) attacking indescrimiatly.
Standard Special Move (Mercury): Diamond Berg
Isaac creates a large ice block, which falls from the sky with about the same speed and power as S64's Kirby Rock. The attack can hurt Isaac too, so get out of the way before it lands!
Side Special Move (Mercury): Plume Edge
Isaac summonns a geyser directly in front of himself, lunching enemies into the air.
Final Smash: Summon Judgement
Judgement appears above the stage, and fires a large beam at the arena. The very edges serve as a safe zone. The beam is very powerful, and does not affect Issac, but has next to no knock-back.
