The 18 known Primarchs (Warhammer 40K) either in their current state or at their height if they are currently dead or disabled, face off against 18 pokemon. If there are not enough feats for some current Primarchs, revert them back to a period where they have enough to be debated.
Deoxys, Tyranitar, Regigigas, Mewtwo, Rhyperior, Yveltal, Steelix, Volcanion, Kyogre, Wobuffet, Dusclops, Zapdos, Magmortar, Regice, Gyarados, Lugia, Darkrai, & Rayquaza.
The 18 pokemon each are paired up with a Primarch and scattered across modern day Earth to random locations in order to duel. Winners are sent to another battle, allowing them provide support for their allies, until this boils down to a 9 vs 9 match.
Pokemon which can mega-evolve may be allowed to do such.
Opponents which are KO’d or killed are considered to have lost. Each battle zone is a 200x200km area. Ring outs from the battle areas count as a loss.
