The Blodex are a species of ant-like aliens from the planet Thoraxia.
The Blodex found Sonic after he was teleported to their planet after fighting the Xorda. Sonic helped save them from the Bzzzz, another insectoid race with whom they were mortal enemies. However, the appearance of an evil Super Sonic caused great devastation on their home planet, which would have turned out even worse had Sonic not intervened.
