Bring a character from outside LoL into LoL
So, kind of an old game, but it amuses me. Make any character into a League champion. Mine would be:
CL4P-TP: Claptrap (Based on the robot from the Borderlands series)
melee support/tank
Passive: Come on Get Down: CL4P-TP can move while dancing and gains +5 move speed while dancing. Taking damage, issuing an attack command, or activating an ability cancels the dancing.
Q: P-PROTECT ME SQUIRE: CL4P-TP retracts his appendages and disables his movement, attacks, and other abilities and gaining +20 armor and magic resist and granting nearby allies +20(+10 % AP) Attack Damage and Ability power for 1/3/5/7/10 seconds or until all enemies within 1000 units are dead. This ability cannot be canceled.
W: AAAAANNNNNNDDDDDD OPEN: Disables target base gate or tower for 1/1.5/1.75/2/2.25 seconds after a .75 second channel.
E: ROBOLUTION: CL4P-TP begins spouting propaganda for the robolution taunting nearby enemies and reducing their armor and magic resist by 10/12/15/17/20 for .5/.75/1/1.25/1.5 seconds. Additionally, allied Blitzcrank, Victor, Orianna, and any allies with a battlecast or mecha skin gain +10 physical damage on hit to taunted enemies.
R: VaultHunter.exe: First cast, selects a champion at random from the pool of champions in that game(any of the other nine). Second cast: Copies the ult of the selected champion.
