the CEO knew he is a villain and i think it is his fantasy to fight against heroes with his organisation, 'The Lab'. so when he find outs that there is a real life Hero in Neo York, i think he went all in with this fantasy of becoming 'The Invader from Different Dimensions'. and i think he would love living in the Ranger Reject Universe.Why go to all the trouble, boss? You're a perfectly adequate villain yourself.
i feel its mostly him rediscovering what he can do before he had amnesia and add in a new perspective and all experiences with all the baddies and villains he fought in neo york that make all the data the lab/company have on Cero to be useless.I like how they're playing with Cero's intelligences. I like it that they didn't have Cero be one of those generic 'I can't do it' hero because they have the same face without having him be stupidly gray. It's a breath of fresh air.
