Ryoku MR4

A pink, rubbery breed of Zan with green armor and large green barbs at the ends of its appendages that are spiked like cacti. It can stretch its limbs, unlike many types of Zan and is apparently very vain about its beautiful skin.

Etymology Edit

Ryoku is a Japanese name that means "strength" or "power," originally a Turkish word.
