Corruptive refers to a playstyle in Super Smash Bros. 4 that Mario (and, by extension, Dr. Mario) Figure Players could adopt and utilize in tournament play. It takes advantage of a unique trait in Mario’s AI that can “ruin” opponents’ play styles to gain the upper hand in battle.
Corruptive trainers teach their Mario amiibo to overuse its side special, grabs, and aerial attacks. In a tournament setting, each set consists of three games. In the first game, the Mario amiibo will lose. In the second match, the Mario amiibo essentially “transfers” its poor training to its opponent; it can then win the second and third matches to win the entire set. Corruptive amiibo were rather unpopular in tournaments; many trainers considered it unfair that an intentionally poorly-trained Figure Player could defeat a well-trained one with relative ease.
In Super Smash Bros. Ultimate, a corruptive playstyle can still exist, but to a much lesser extent. Figure Players can become immune to corruption by switching their Learn button off. As a result, corruptive characters are hardly mentioned, as most FPs are sent to tournaments with learning off.
