Goku Kitsun is one of the major protagonists in Kotsu's Rise. He is one of Kotsu's companions, along with Goten Jippensha. He joins Kotsu Shadereign upon meeting the boy and realizing he is the boy with the key that King Mickey asked him to find and follow. Goku has become fast friends with Kotsu since meeting him.
Goku has orange hair and brown eyes. He is the tallest in Kotsu's trio, but not nearly as tall as Barku Lonestarr, another member of the rebellion. Goku has a thin but sufficiently strong build. Goku's hair is probably the longest comparatively among his teammates.
Goku is very calm and laid-back, usually serving as peace-keeper within his group. He prefers discussing things reasonably than fighting, but resorts to the latter when necessary. Goku is also known to be very polite, and shows kindness to all that meet him. Strictly within his nature of using a shield as his weapon, Goku does not want to become stronger. He merely wants to be strong enough to protect his loved ones. Goku is a very loyal friend.
