Shinya Arino

Neutral B - Panic Throw
Arino is able to take any projectile (and I mean ANY projectile) and return it to the sender. The last few frames are similar to Toon Dr. Mario's high-5 prescriptions. This move is also a quick grab-n'-throw.

Side B - Japanese Snack Throw
Arino throws 1 of 3 different japanese snack foods (pocky, edamame, green tea ice cream) and they have 1/3 chance of ecoming edible treats upon hitting the ground. The pocky is razor-sharp, the edamame beans dissolve liquid traps, and the the green tea ice cream is similar to Patrick Star's ice cream (including the chances of becoming a slip trap, 1/8).

Up B - Super Arino
Simple. You acsend for 10 seconds and you can cancel by pressing A/B. P.S., moving the analog stick to either side does a dashing punch similar to the rainbow punch (in Lawl Ult.).

Down B - Tricks and Tips
This is similar to Don Ramon's la calavera, except no one in the middle of the board is stunned and no matter which move you do, you have to wait a while before you can reuse this move. Plus, he does 3 different moves, which are as follows:

A - Fire
Anyone in front will feel the burn!

B - Ice
The closer an opponent is, the longer he/she is frozen.

R - Magnet
The function is similar to the PSI Magnet, except it's a 1-second flash.

Final Smash - Arino's Challenge (Arino no Chousenjou)
You can choose 1 of 4 characters from Game Center-CX: Arino no Chousenjou 2 to play as. If you don't choose in the next 10 seconds, it chooses automatically. Here are the 5 choices:

Wiz-Man
Pressing A casts fireballs while pressing B casts a freezing spell. During this choice, boo look-alikes from the game will hurt you if they touch you and vice versa.

Demon Returns
Enemies appear and opponents can't hurt them, but they can get hurt by them. As the demon, you can jump on them and spin them by slashing (press A). Pressing B shoots tornadoes that spin the opponent right off the ledge.

Super Kung Fu Fighting
Pressing A punches and pressing B kicks. Other goons will fight for you. If you get enough power, you can do supercharged special moves that are performed in the basic style of a regular fighting game.

Super Robot Ninja Haggleman
The moveset is similar to Ryu Hayabusa's possible moveset. Minus the final smash, plus extra power.
