Master Hand

Neutral B - Handgun
Each shot does 25% of the damage it dealt in the original games. Hold B to charge up how many shots are fired at once. The maximum amount is 3. If that happens, you must wait 45 seconds for it to cool down.

Side B - Shove It
Anyone in front of you is pushed away. The farther an opponent is, the more damage dealt. This can also be charged up for more impact, but not so much that it overpowers you.

Up B - Out of Reach
This is an obvious recovery to use. Anyone who gets in your way is taken and thrown behind you as if to say "Pfft, annoying." Also, you ascend for 3 seconds.

Down B - Stone Shockwave
The higher you are when you use this move, the bigger the shockwaves. If any opponent is directly under you, he/she is plowed into the ground (only if you're high enough). As Queen Elizabeth would say, "Let them eat poundcake!"

Final Smash - Double Laser
Crazy Hand comes along and grabs his bro. They form a gun and then shoot a powerful laser from the top right corner that can instantly KO anyone.

Trivia

 * Even though Master Hand already appeared in Smash Bros, he's still unlikely to actually be a playable character (aside from the GameShark codes in SSB64, the famous glitch in Melee, and the available hack for Brawl).
 * The final smash was not actually in the game itself.
 * Most of the standard attacks came from a hack showcase video posted by supermasterhand.
