Nemesis

After several failed experiments, the series 3 Nemesis named "The Pursuer" was the first B.O.W. without brain damage and mental retardation. What an accomplishment.

STARRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRS
A very angry mutant who hates the firmament, and all of the one associated with them, including a small team of cops.

Season 3
During the Dimensional Merge phenomena, Nemesis suddenly appeared coming from the future, apparently seeking someone or something (Probably S.T.A.R.S.).

Season 0
After his involvement in Raccoon City, it was thought no more Nemesis-T Types were left. But that was wrong as somehow, a master of Pokémon had somehow acquired one at some point.

Episode 5

Kane agreed to fight with his Pokémon Nemesis to "relieve the past", unluckily for his opponent.
