turn a gundam (mobile suit)
The titular mecha from the Turn A Gundam anime series from 1999. Also known as the "Mustache Gundam" in otaku circles.
The SYSTEM ∀-99 ∀ (read as: Turn A) Gundam is considered the strongest Gundam in the entire franchise because of its Moonlight Butterfly superweapon, and also due to its expanded specifications in the manga.
It is notable because it was designed by the legendary American science fiction film designer Syd Mead.
