So anyone is reading this manga? I started 2 weeks ago and need to say that is pretty good title.

Kind of reminds me of Doom seeing as it takes place on Mars. 

I've heard about it, and seen some images from the manga. I might check it out. Some of the more brutal scenes remind me a lot of Gantz. Perhaps that's just me. I was actually just about to ask the Advocacy who they think would win in a fight between a Guyver/Gigantic/Exceed vs those roach creatures. I find them very frightening, yet fascinating. 

Normal Guyver would might have a problem dealing with some roaches, but Gigantic and Exceeded in my opinion would be enough. Roaches cold blodded killing is frightning - no anger, emotion or lust just simple murder. Fascinating is the fact that they are not corrupted by power like human, they seem to act as one.
