Son Goku

Son Goku (also know as the Four-tails) is one of the nine tailed beasts. Son Gokū is a red-furred and green-skinned monkey, with a body-build of a gorilla. It has eyes with yellow irides and white pupils, spike-like protrusions along the length of its tails, elongated blunt fangs, and two long horns curving upwards on its forehead like a crown (both its fangs and horns are dark-tipped). In its mouth, Son doesn't have a tongue, but has an opening that is shaped like a dome volcano.
