Half of them are boasting about their literal "evil nefarious plans" and the other half believe they're doing good. So is one half on the side of evil and the other on good?

Another brilliant thing they do is say stuff like, "We need to keep our plans secret"

And what better way to keep a secret than to have half a dozen guys block the road wearing your big doofy red uniforms.
Real stealthy guys, expert espionage. Don't even bother changing into your regular clothes. Go all out and discuss your plans in public wearing your big red uniforms.

And of course, what is their ultimate plan you might ask? Why, get rid of the oceans so we have more dry useless land to work with. Brilliant! Water, I mean, who needs it right? It's pretty much fucking useless right? It's only the source of most life on this earth. Yeah just get rid of that shit. We need more land for "humanity's grand stage".

Bottom line, Team Magma is pants on head, anally fucking retarded.
