YMMV / Pokémon Nightmare: Invasion

• Ass Pull: Lou showing up as the second to last boss and revealing himself as the Greater-Scope Villain behind everything is barely hinted at and comes completely out of nowhere with no explanation beyond him just saying that. The plot then promptly forgets about it so Jack can take on the true Final Boss.
• Complete Monster: Mewtwo is the result of the experiments that lead to the disappearance of Azure City by the Alazkazams. Mewtwo would end up going rogue and fleeing, transforming the people left there into mindless slaves who would eventually all be killed by Jack. Mewtwo returned to the Gene Co. building and killed the remaining four Alazkazams who created him, simply because they wouldn't submit to him. Mewtwo would end up being upgraded and completed by Gavin into Mewthree by infusing him with all the knowledge and memories of the people of Azure City. After the process is done, Mewthree kills Gavin and three scientists and begins his plan to destroy the world and recreate it in his image.
