Tachikoma are fictional walker robots endowed with artificial intelligence (AI) that are featured in the Ghost in the Shell universe. They appear in the manga created by Masamune Shirow and in the Stand Alone Complex sub-universe. Nine of them are initially deployed to Section 9.

Shirow is noted to keep numerous spiders as pets.
