Shouldn’t you put a spoiler warning for people who haven’t read it? That comic is pretty recent.

There, I edited it.

By the way, Geo-Force has turned against heroics in the past, as he hasn’t always been mentally stable. He came around in the end then and may very well easily do so again now. For the record, the original Terra (Tara Markov) was a sociopathic murderess, but the PE version doesn’t seem to be evil, although she’s no saint.

I get where you come from as I mostly hate heroes turning bad, BUT, I think that turning Brion into a massive criminal, especially under these circumstances, is really helpful for his character

Like he has been such an afterthought in the comics for years, it is nice to see him finally used in a position that could gain prominence in the future. Plus, the way in which he broke up makes sense, thus allowing us to understand him and make it easy for him to potentially become good again in the future

I just hope we see more of him, since he truly was positioned after Shadow War as a big player in DC's future

Can someone tell me why Geo-Force has turned evil in the past, does he have mental illness like Terra.

Well it seems to relate to Bendis’ run on Checkmate

“Evil” is an exaggeration, Riley. Sometimes, a hero ends up fighting other heroes and becoming an antagonist because of a difference in values or because other circumstances have pushed them over an edge. That doesn’t make them evil. In New Earth, Brion ended up battling the heroes he called friends because their interests clashed with his when it came to how Brion wanted to lead the people of his nation.

Oooook?

It makes sense geoforce would do this I mean look at what Deathstroke did his sister and what Damian Wayne's mother did to his country it makes sense he wants revenge and in the end Batman let's her go.
