FMSZ-007II Zeta - Appears in Multiple Kazuhisa Kondo works, all designed by Kazuhisa Kondo
Just various Kondo Zetas. I think they are fun, he really loves making the Zeta's forehead jewel a lot larger. This is one of those mobile suits of his he puts in a bunch of his manga and stories. I believe these also show up in some of the PC-98 games? Though I don't know for sure.
