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).
