Heroes Kao

A kao model.

Kaos are large circular rocks that have spikes protruding from their sides and have faces on the surface.

They are first seen in Ocean Palace in Sonic Heroes. Kaos are also seen in Sonic Generations at both Acts of Seaside Hill in some areas, as well as in Sonic & All-Stars Racing Transformed in Ocean View.


When a team enters the area where there the Kao are found, they will begin rolling to chase the team and will try to roll over the team. Eventually, two more Kao will roll along with the first. The team must outrun the Kao in order to escape, continuing the first-level-run-from-the-danger theme.


Due to its huge weight and size, Kao can break anything smaller in its path. In gameplay, it can roll fast enough to keep up with the playable character. Kaos appear to be semi-controlled: when it collides with a character it stops, and when chasing a playable character it adjusts its speed to him/her rather than moving at constant speed.
