Wally

Wally is the deuteragonist of Ultimate X. He is also a Citrakayah and X's best friend.

Personality
Wally is mostly a silly and goofy person. He loves to tell jokes and pull tons of pranks. Wally can sometimes be somewhat of a trouble maker and doesn't think before acting. Aside from all his goofiness, Wally is a good person who cares about his family and friends, including X.

Appearance
He looks just like Fassttrack from Ben 10: Ultimate Alien except that he has blue eyes and doesn't have an Omnitrix/Ultimatrix symbol (well duh).
