Lanius
Lanius was a former Scolemis general and the head of the Kanto arm of the Pokepan invasion during the events of the AU Arc. A brutal though intelligent combatant three times the size of an average Samurott, he was a fan of the Roman practices of crucifixion and decimation and headed an army of slavers and murderers. Lanius was also a Social Darwinist with a firm belief that the strong had a right to rule over and cull the weak. After Tagg, Tracer, Every, Mezzo, and Fool and their mons defeated him in an epic battle, (With some help from Ian and his friends.) Tracer paralyzed him below the neck using Tagg's own dagger to make him even lower than those he considered lesser. Eventually he ended up putting his energy into bloody war poetry, and in the PMD-B timeline ended up creating an entire settlement of larger than normal marine mammal mons within PEFE HQ.
