not really thinking about anya in the gurren
the mordred is perfect for her since she doesnt have the emotional intensety to be a hot blooded high speed pilot (the more you scream. the better you are)
plus theres just something fitting about a little girl piloting a heavy assualt mecha
and as for the gurren
i think it would get the nuke tech upgrade based on nina's work
gurren freedom mk III (now 200% more expensive)
then kallen steals it back and much ass will be kicked
