I don't see Roon anywhere though

Look in the bottom-right, behind the mecha.

EDIT: After looking through his feed, I'm pretty sure this mech is the artist's self-insert - he uses this design when there's an Azur Lane commander needed. I'll just tag it artist_self-insert for now.

ok, why's the commander a gundam?

Because it's one of the few things that can survive here while also eliminating the chances of him getting raped by one of the clinger ones?
