The power to
use the abilities of giants. Variation of Mythic Physiology.
User with this ability either is or can transform into a
giant, humanoid being of prodigious size and strength common in the mythology and legends of many different cultures. Most obvious changes are increased size (ranging from relatively normal-sized but big to huge to closer geological scale), strength and endurance. Generally, giants lack any real supernatural abilities, but they can have the same ability to learn as, for example humans, and some have truly impressive powers.
Decelerated Aging - The life-span of a giant is variable and rather un-defined: some live vastly longer than humans, a few have shorter life-spans, and in most cases it isn't mentioned at all.
