GP-06 is a Titans remnant MS that gets destroyed by Amuro in 0091 and appears to have some kind of psychoframe. Its remains land on the moon and is rebuilt into the Moon Gundam
GP-06? What happened to the GP-05!? (I totally need to collect all the GP-line of models since I'm such a big 0083 fan. I have the GP-01,fb,03, and 04. Still need to build the 02.)
Oh right it's this guy isn't it?
Edit 2: No I guess that's the regular G05... I'm confused...
