fuchikoma

The AI-controlled spider tanks from the original Ghost in the Shell manga. Because of a trademark claim arising from the Ghost in the Shell Playstation game, Fuchikomas couldn't be used in the Ghost in the Shell Stand Alone Complex TV series, so they were redesigned and renamed as Tachikomas.

Also see Logicoma (from Ghost in the Shell Arise) and Gertsecomma (from Koukaku no Pandora).
