The heights aren't correct. Nena should have been drawn shorter than Feldt and Wang Liu Mei.

There's 2 or 3 females not from Gundam 00; who are they, and why are they here?

Yeah, I don't recognize the woman on the far left, the girl behind Saji and Louise, or the girl in front of Graham.

I figured they were from some 00 spinoff manga that I haven't read, I didn't have any luck trying to find who they are.

The three Unknowns are from the 00F side story manga the story coincides with 00 and this is also where the Astrea is from

where are the lock on brothers T^T

The girl on the left, the girl between Saji and Louise and the girl in front of Graham are all linear train attendants (HRL, Union and AEU from left to right). The nekomimi girl is Hanayo (not Gundam Meister 874) and the blonde girl with white dress is Sherilyn Hyde, both from from the sidestory manga 00F.

I removed the Tieria Erde tag since I honestly can't see him in this picture.

Nena's also standing on air, apparently.

For Tag Panic! Pool??
I sure hope so.
