Nihilist!Tagg

Nihilist!Tagg, also known simply as The Nihilist is one of Tagg's aspects, and the most dangerous and evil of all. A manifestation of Tagg's inner pain, he was normally kept at bay by the numerous other aspects inhabiting Tagg's mindscape.

Orange Islands

However, during the J-Team's time in the Orange Islands, Swindle decided to steal Cynical!Tagg after overhearing Tagg complain about him to DS.

Taking this opportunity to be free, Nihilist!Tagg hijacked Tagg's body in short order on October 15th, and then mind-controlled Muddy, Doc, Crochet, Thresher, Sentinel, Limna, Draca, Hydreigon, and Helios, as well as Cobalt offscreen. Victini, being a legendary, was able to resist Nihilist!Tagg's control, leading him to seal him inside his GS Ball. Xatu managed to resist just long enough to teleport them away from the hotel, preventing Nihilist!Tagg from going on a murder spree immediately.

Luke, Tracer, and DS along with their mons confronted him there, after he had Doc, Sentinel, and Xatu use Telekinesis to bash the three trainers against trees and each other. The battle was a hard fought one, with Nihilist!Tagg using his mind-controlled mons to put Vlad and Treeo in the ICU, as well as Xatu teleporting in Coulomb to fight at one point, the Eelektross mauling and burning Guardé and Chord. Eventually, Diesel was able to put Tagg to sleep and Swindle returned Cynical!Tagg, allowing the combined aspects to defeat Nihilist!Tagg and placing him behind a stronger seal.
