Metal Gigantuar (Monster)

An extremely rare, metallic cactuar that yields an immeasurable wealth of experience to the brave souls who can defeat them. It absorbs as much power as it can from the world around it into its silver body, growing larger and larger the more energy it obtains. However, there is still no clear answer as to why it develops thorns as it grows. It has virtually no fear of humans who pale in size to the gigantuar.
