Panda has 2 other siblings, They are imbued as different modes. Basically Panda can switch between his sister which is a Triceratops, by switching to his "sister's" core, Panda can transform into a bipedal Triceratops form. By switching to his "brother's" core, Panda can transform into a muscular gorilla that retains his normal colour scheme. Panda is much stronger and faster in this form but at the cost of rapidly draining his cursed energy.
