Uses Lucario as a base because of Aura Storm, defensive collisions, command grab and chargable projectile. Model either from Brawl (but edited to fix proportions), Other M (edited to fix beak, resize wings, rig toes, etc) or hybrid of Super Metroid, Zero Mission, Other M and Brawl Ridley (but this will require completly custom model, so, previous 2 are easier to do).
Note: only tail blade is useful while tail itself is pretty much useless with its low knockback and damage.
Weight - 100 (same as Mario's)
Falling speed - 0.012 (a bit lower than Bowser's)
Jumps - 5
Jumps height - higher than Charizard's.
Running speed - a bit higher than Bowser's.
Walking speed - near Bowser's speed.
Air mobility - 0.07/high.
AAA jab - 2 claw swipes and then tail swing (Ridley rotates 360 degrees performing it, tail base has moderate knockback for this one instead of low knockback).
Side tilt - Ridley's tail swing attack from Other M, but done while standing.
Up tilt - Bowser's UAir with fire added to his mouth (sweetspot) and less startup.
Down tilt - tail swipe that hits twice.
Side Smash - spins his tail like in 2D games and then thrusts it forward.
Down Smash - spins 360 degrees with tail extended to knock away opponents from the front and behind him. Has long end lag.
Up Smash - wing smash. Can't properly describe it, but he crouches when doing that. Has long end lag.
UAir - same as Wolf's.
DAir - pogo tail seen in 2D games, same properties as PM Wario's, but he bounces up higher.
FAir - like side tilt, but in the air and takes less time.
NAir - Charizard's NAir, but faster at the end and tail blade has meteor hit properties.
BAir - thrusts his tail behind him, then swings it up and down.
Grab - uses his arms to grab. Has low start up and a bit of end lag.
Grab attack - bites opponent.
Forward Throw - basically Other M wall scrape grab, but on the ground instead of wall.
Up Throw - throws opponent up, then jumps very high at high speed, knocking opponent even higher up (but he still ends up above opponent), before going down at high speed, crushing him/her/it under his feet.
Back Throw - stabs opponent with his tail, then throws away behind him.
Down Throw - slams opponent into the ground and, after opponent bounces up, impales him/her, then roasts with firebreath before shooting a fireball at opponent, launching him/her.
Neutral B - charges up a giant fireball. Goes through most of projectiles, but still can be reflected and absorbed.
Side B - like Firebrand's Bom Voyage on the ground and like Firebrand's Light Demon Missile. Has nearly no start up and end lag in the air, but has both (mostly end lag) on the ground. Doesn't puts him in a helpless state, but he can't use specials that could be used as a recovery. If hits when in the air, he can reuse side B and up B again.
Down B - after 100+ frames of roaring, makes his skin reflective and harder, giving him light armor, but becomes slower. Will last for 5 seconds, using Down B again will remove it quickly. Timer starts counting only after he ends animation or gets hit. If he gets hit while roaring, he will still have reflective skin. Has some purple aura around his chest area and becomes a bit darker.
Up B - UMvC3 Firebrand's Strong Demon Missile (but goes higher than Firebrand). Before someone will say anything about something like vBrawl Pit's Up B, this one, along with ROB's Up B, was removed for balancing, so, it has to be something offensive. It won't hurt him too much since he has 5 jumps and Side B (or Up B) to recover. Doesn't puts him in a helpless state, but he can't use specials that could be used as a recovery.
Final Smash - Plasma Beam. vBrawl Lucario's Final Smash with high turning speed, high damage and knockback at the cost of low horizontal range. Once caught, opponent won't escape unless you will move beam away for some reasons.
