Transmogrify, also called Transmog, is an ability that was introduced in Destroy All Humans! 2.
Transmogrify was introduced in the second game. It is the ability to transform matter, which is used to convert inanimate objects or vehicles into ammunition for Crypto's weapons. In the fourth game, Transmogrify can be used on humans too, by making their heads explode to kill them instantly and retrieve a collectible brainstem, simulating the Brain Extract ability.
