Um. Starship Troopers had very advanced power armor? It could fly, had flame throwers built in, crazy grenades, electronic warfare, communications, and machine guns.
"Starship Troopers (宇宙の戦士, lit. "Soldiers of Space") is a six part anime OVA produced by Sunrise/Bandai Visual and released in 1988. It is based on the book Starship Troopers by Robert A. Heinlein that was published in 1959.
Miyatake Kazutaka of Studio Nue originally designed the power suits in the OVA for the Japanese edition of the novel in the early 80s."
When i mean advanced power armor, i imagined it as a bulky, large, but not exactly walking tank. Now if its an artists idea of it, thats fine. But that just looks like armor. I just really don't see starship troopers. And of the OVA, the "Arachnids" are flying jellyfish. Granted they will mess you up, but not a bug.
