General Idea: Glass cannon with tons of disjoints and ridiculous stage presence, but fairly easy to KO when he's in disadvantage.
Attributes:
-Weight: similar weight to Kirby, he's a puppet made of wood after all. Not very heavy.
-Ground speed: slow. faster than ganondorf in smash 4, but not by a significant amount.
-Air speed: Slightly slower than Jigglypuff/Wario.
-Fall speed: very floaty, around Rosalina level. landing is gonna be a problem for him.
-1 midair jump
-cannot crawl
Two Unique mechanics:
-Geno Boost allows him to be stronger and faster sometimes, see Down B.
-Rocket punch, some of his moves send out his fist, or both fists. These moves are typically very fast, but they can't be used again immediately, because the fist has to travel back to Geno before he can use it again. Think of Link's boomerang or K rool's crown. He has two fists, so the 1-fist moves can be used twice in a row with a slightly different animation. 2-fist moves can only be used once before waiting. The fists do NOT have a hitbox on the way back. Also, if a rocket punch hits the ledge, it'll pull Geno in similar to a tether.
Moves:
Jab - A fast one-two punch combo, followed by launching a fist forward for the finisher. The fist doesn't travel very far forward.
Ftilt - A forward punch followed by a flex for two hits. Based on the animation for the arm cannon, but doesn't fire bullets.
Dtilt - Low sweeping kick, creates stars in front of him for a bit of a disjoint.
Utilt - Geno lifts his hat up like in the item use animation, then puts it back down. Short range, but fast.
Nair - He spins in a circle, with the geno whirl thing surrounding him. Very fast move.
Fair - He shoots his hand forward for a rocket punch, which then returns to him later. It travels like Villager/Isabelle fair/bair, but then moves back after accelerating in the opposite direction.
Bair - Similar to Fair, but he launches both hands and is launched forward slightly from the recoil. Similar function to Corrin's Bair, but longer range/disjoint.
Upair - A star pops out above Geno while he does that "praise the sun" pose, a slow powerful attack with a small hitbox, great kill move, bad for juggling. Similar to Zelda's Upair.
Dair - Geno stomps downward, both of his feet rocketing downward a bit. Similar mechanic to rocket punches, but only applies to this move. Functions mostly like Megaman's dair.
F-Smash - The charging animation for this move has him open his arm more and more for the bullets he's about to fire. Uncharged is finger bullets, half-charged is arm cannon, full charge is two handed arm cannon. Not a projectile, has the range of Mii Gunner fsmash. Kinda weak uncharged, but very strong fully charged.
D-Smash - Sends a rocket punch in both directions, one after the other. Like Mii Gunner's dsmash, but with projectiles. Uses both fists, of course.
U-Smash - Geno Blast! It sends out a pillar of rainbow light above him similar to Palutena's usmash, but directly above him instead of in front.
His grab uses the rocket hand mechanic, but if both hands are away, he can still grab, just with bad range. Works mostly like a tether grab, but he doesn't have a zair.
His throws involve tossing the opponent in the direction of the throw, and covering them in stars as he does. His down throw is stepping on them and firing some bullets before they get launched away.
Specials:
Down B - Geno Boost! 60 frames long, but if it finishes he deals 1.2x damage (not knockback) and moves a bit faster for 15 seconds. He cannot use it again until 25 seconds have passed, even if he was interrupted before it came into effect.
Side B - Geno Whirl! A very fast projectile that moves until it hits a wall or goes offscreen, piercing players. Max range is longer than left side of FD to offscreen. Doesn't do much damage or knockback, but if you press B again when it hits the enemy, it becomes a pretty good kill move. The hitbox is very small, and pressing B makes it have the strong hitbox for 1 frame, and you can only do it once, making it very difficult to use. Geno can't move until the projectile is gone.
Up B - Geno Flash! Geno transforms into a cannon and shoots himself out of it. Similar to Diddy's up b, it can be charged to go higher, but he will fall while using it. He can't redirect himself midair as well as Diddy, and the move deals no damage except for right at the cannon itself, but he can act very quickly after firing. Can only be used for recovery once midair. VERY bad for recovering, but incredibly useful movement option on-stage.
It goes much higher when grounded. If you use Up B midair after using it once already, Geno will explode and create a VERY strong kill move, followed by him going into freefall.
Neutral B - Geno Beam! Basically, a chargeable falcon punch laser. There are four levels of charge, based on the star charge meter.
-One star charge takes about as long as a Warlock Punch at minimum, but isn't nearly as strong due to having much more range. Strong enough to kill at around 120% on most characters.
-Two star charge takes about 2 seconds (fully charged smash attack time, approximately), and is slightly weaker than a Falcon punch. The laser is now about half as tall as Geno.
-Three star charge takes about 6 seconds total, and is deadly. Approximately as powerful as Jigg's rest. The laser is also as tall as Geno's entire body.
-Four star charge takes about 6.5 seconds total, and is worthless. He shoots out a star projectile that deals minimal knockback and damage.
Final Smash: Wish!
Geno summons a large star in front of him, catching one person and sending them to star road, where the 7 star pieces assemble, and Geno makes a wish... followed by everyone that he caught in it being launched.
