Be disappointed, rather them make up a final boss than pick one from a franchise. It will look like they are favoring that franchise more than the others. Like if Santa Monica had control over what Superbot chooses, the final boss would be something God of War related. I think we have enough of that as of now.
Now that he's said it I actually have an idea for him. I need to contact him eventually.
People have stated on numerous occasions that the Negativatron is in a stage. Strangely though, so is Doctor Nefarious.
If anyone's checked out the final boss music, there's a large Doctor Nefarious-esque theme. So what if...just hear me out...Doctor Nefarious and the Negativatron pulled everyone in?
I say there should be one more villain to jump in with this, so I'd like to bring up that there was a recent hearing of the likes of Baron Praxis, which would make perfect sense with the two above.
I'm not saying this is going to happen nor am I saying it makes any sense, I'm just having fun, so here:
What if, Baron Praxis collaborated with Doctor Nefarious, and had Nefarious contrive some way (as he is a doctor, and a scientist) to have the Dark Eco Crystals, somehow power up the Negativatron?
And through this, the final boss would be Doctor Nefarious and Baron Praxis standing on a giant colossal Dark Eco Negativatron, who near the end of the fight would be smacked away Taboo-style, for the likes of Polygon Man to appear?
Either way it can't be him,Omar said the boss is not necessarily evil & he did say ps1 players will get a sence(ps1era) of who the boss is in progression of arcade mode.
