Patrolling centipede bot.

— Description, Sonic the Hedgehog Encyclo-speed-ia

The Geji-Geji[1] (ゲジゲジ[2] Gejigeji?) is an enemy that appears in Sonic Advance 2. It is a mass-produced, centipede-based Badnik model created by Dr. Eggman.


The Geji-Gejis each resemble a centipede. They also have a set of large pincers.



In Sonic Advance 2, the Geji-Gejis appear as enemies in Egg Utopia. In gameplay, they crawl slowly through the air. They appear between the floor and ceiling. Take care not to touch their spikes. However, an attack to their spike-free heads will stop them.

Powers and abilities

Geji-Gejis are able to defend themselves with their spike-covered bodies. They can also crawl upside down.


  • "Geji-Geji" is Japanese for "centipede".
