What is your skillset? What is your passive, q, w, e, and r?
NOTE: You do not necessarily need an ultimate, Udyr does not have one.

Mine:
Passive: Play Game:
When I use an ability, I start to play a game with intense concentration for a short time, decreasing my damage recieved. However, I also deal less damage for a shorter time.

Q: Controller Whip:
I wrap a controller around my targets legs, like a whip, tripping them and causing them to be stunned and dealing damage.

W: Throw System:
I throw a random game system at the enemy, dealing damage based on the system and adding an additional effect.
Wii: Causes the enemy to be extremely bored, putting them to sleep for a short time.
Playstation 3: The enemy takes heavy damage and is slowed.
Xbox 360: The enemy is in awe of the epic system, taking true damage and causing the Play Game effect on them.

E: Take a Drink:
I offer a drink of a fizzy substance to a nearby ally, healing them and casues the Hyper Effect, increasing their attack speed.
If used on self, I take a drink of a stronger fizzy substance that I stash for myself, healing me for less, but causing a greater Hyper effect.

R: League of Legends:
I play League of Legends on the field of battle, summoning a random champion to use their ultimate. The champion will always be random, but will never be a champion who has no ultimate or whose ultimate is a passive/transformation ability. If it deals damage, it deals damage based on rank of this ability and scales as if I had additional attack damage or ability power which is also based on rank. If the ultimate is a self-effect(such as Sion's), I gain a lesser effect on the ability.

Passive: Minion Master

R: Promote (150/200/250 mana) 150 second cooldown
Promotes a chosen minion, granting it bonus attack damage, health, armor, and magic resist. If that minion is a recruit, it becomes a permanent minion. I can have only 1/2/3 such minions under my control at a time.
