The omnibian is a huge slick-skinned frog creature, about the size of a cow, with three bulging eyes instead of the usual two. This strange Simic mutant has the ability to transfer its own genetic pattern through its long elastic tongue.

The omnibian is a genetic creation of the Simic Combine. It has cytoplasts on its back and under its chin. Creatures that it hits with its tongue temporarily assume the frog's general size and shape.

"This creature has hyperevolved chameleonic abilities. It no longer mimics its surroundings, instead forcing them to take on its form." -Simic research notes
