Orcas (commonly referred to as killer whales) are large aquatic mammals in the Sonic the Hedgehog series. These large, non-anthropomorphic animals populate seas and coastal parts around the earth. In numerous games since Sonic Adventure, Orcas appear as large obstacles that pursue Sonic the Hedgehog through many beach oriented Zones, most notably Emerald Coast. Depending on the game, the sequences with Orcas may include automated spectacles.
- The most famous appearance of the Orca was in Sonic Adventure, when it was chasing Sonic the Hedgehog through Emerald Coast.
- It also appears in the infamous game Sonic the Hedgehog (2006) in Wave Ocean, and again in the 3DS version of Sonic Generations, once again in Emerald Coast.
