Kaio Ken Super Saiyan

This form is first used by Goku Jr. as a teenager. The form can only be accessed by going Super Saiyan then going Kaio Ken. This causes an orange aura and the Super Saiyan's hair turn orange. Edited by King Kai, the form later has a squiggly K on their forehead (similar to people controlled by Babidi). This form has its power quintoupled compared to an average Super Saiyan. Sadly, though, your body gets tired quicker.
