Waluigi

Waluigi is the final form that only exists because Wa, Lu, and Igi fused to become him. Waluigi was powerful and dangerous in the beginning, But Luigi killed Igi by using his secret tactic-doing absolutely nothing.

After failing to defeat Luigi, Waluigi has been seeking revenge. While he is weaker than the day he escaped from the Meme Hell, Waluigi is still a formidable foe. Waluigi was temporarily a meme master.

He also later started .W.A.H. and Waluigi's Army, two factions in The Wah War.
