Omni-Mare is Ben’s pony-inspired form.

Omni-Mare possesses extremely strong magical capability. However, due to Ben himself not really understanding anything about magic, or even having used it, he initially has trouble figuring out how to use it. In fact, at first, he didn’t even realize the magical skills of the form. At least, until he started singing.

As it turned out, the form also seemed to come with the innate desire to sing, and while singing, it allowed Ben to concentrate and utilize his magical powers to influence his surroundings, from a variety of magical attacks, to being able to repair or heal damage. Perhaps with time and practice, though, he could potentially figure out how to use these magical powers properly without the need to sing.

Omni-Mare also possessed the ability to utilize his magic to mimic the various skills and capabilities from his arsenal of alien forms. By giving a quick stomp with his back hoof, it would cause the Omnitrix symbol on his flank to cycle through and select one of his unlocked aliens to temporarily instill him with the essence of that form. However, this did require concentration on Omni-Mare’s part to keep his magic going.

Omni-Mare was also naturally pretty quick with some powerful kicks!
