I had some ideas for Sans in Smash Bros:





Rapid standard attack: He breaks out his trombone and hits the player with it as he plays it.



Grapple: He grabs them by the hand, while a whoopee cushion is heard with each moment of the grapple.







Special Attack: Toss 'Em a Bone - self-explanatory, he tossed out a bone that hits anyone in its path.



Special Attack Toward: Gaster Cannon - pretty self-explanatory. He summons one of his laser-shooting dragon skull things towards the direction he's facing.

Special Attack Up: Boning Up - He uses his bones to propel him upward, while anyone standing too close takes damage and knockback.

Special Attack Down: Try and Ketchup - He breaks out a ketchup bottle and squirts it on the ground around him. If he walks on it, he regains health. Enemy players will slip on it and hit the ground.





FINAL SMASH: Megalovania - Anyone standing too close to Sans gets pulled into a fight screen right out of "Undertale", his left eye glowing that haunting blue, as he then states, "On days like these, folks like you...SHOULD BE BURNING IN HELL!" They are subjected to the same attack Sans uses in your fight with him on the Genocide route, taking heavy damage for each hit. At the end, he laughs, "Get dunked on!"





Victory Animations:



1. He's walking away from the screen, only for the camera to come up to his left shoulder...he turns and grins with that glowing blue eye, saying either, "Get dunked on!" or "If we're really friends...you won't come back."

2. The camera circles him as he plays the trombone...then he winks at the player.

3. He's drinking from a bottle of ketchup, finishes, then goes, "Aaaaaah, that hit the spot."





Possible stages-





Underground Realm: A scrolling battle stage that follows Frisk's trip into this underworld filled with monsters.





Photoshop Flowey: Hey, Kraid got a boss stage he presided over. Why not Flowey's ultimate form from the Neutral Route? Much like that battle, you not only face Flowey's monstrously WTF form, but each of the short bits of dodging the hazards this psycho flower tosses at you...and if you hit the Action button, the hazards turn into a means to heal the characters.





Possible Assist Trophies:





Papyrus: Naturally, Sans' silly brother tries to deploy his wacky puzzles upon the other players, with 50-50 chance of them successfully causing damage to the other opponents. If the puzzles fail, he remarks, "Whoopsy-doopsy. I have to use the bathroom. All of you have fun!"...and he jumps out a window.





Undyne: Undertale's Captain of the Royal Guard attempts to impale the opponents with her spears, springing up out of the floor.





Taunts: He delivers one of his puns about the other combatants, then winks at the player while a comedic drum plays a short riff.Flowey: He pops up out of the ground, and attacks the other players with his "friendship pellets".
