The user can transform into animals, as well as use the abilities, traits and appearance/physiology of animals by rearranging their own DNA structure. Users may be able to transform into alien animals and/or animals they have never encountered, such as Dinosaurs. Some may have this ability from an empty genetic code, allowing them to accept any form from which they have a DNA sample, others may be able to alter their form mentally and change just by seeing and mimicking animal features.
The character can turn into any type of animal larger than a fly. In animal form, the character has only the power of speech, his intellect and the powers of that specific animal. Thus, if he's a sparrow, the hero is small, can fly, has 180 degree vision, and other traits of that animal. If an elephant, he is huge, has the equivalent of Robotic Strength, can run 30 mph ( 48 km), has a prehensile trunk, and so on. The animal metamorphosis has many advantages. Not just the creature's natural abilities, but the fact that it can make a fantastic disguise that nobody expects; no one is likely to pay much attention to a common animal like a horsefly, mouse, squirrel or sparrow, or suspect the creature is spying on them or tailing them. Likewise, a small animal can squeeze into places a humanoid cannot, and an animal predator is likely to have considerable shock value and Horror Factor to scare people, especially ordinary people, away.
While in animal form, the hero can use any of his other super-abilities or powers, but they are at half their usual potency; reduce damage, range, duration, etc., by 50%. Although the hero can speak in animal form, he must tum back into his natural humanoid form to cast magic spells, operate most machines or use
a weapon. However, most psionic abilities can be used as usual while in animal form.
