Waluigi debuted in Mario Tennis in 2000 as Wario's partner and Luigi's rival, quickly becoming a fan favourite in Nintendo's Mario spin off games including Mario Kart, Mario Party and Mario sports titles. His exaggerated voice lines were widely clipped and shared on soundboards and in fan edits during the 2010s, where short motivational shouts became reaction sounds. This power up line survives because it sums up his loud, theatrical personality in two seconds and fits any gaming moment built around levelling up or charging forward.
