I agree with Ultimate Humungousaur. Even though Swampfire showed up in almost every episode of Alien Force, it was because Ben was limited to 10 aliens at the beginning, and progressed to new aliens. Swampfire also made daily appearances in Ultimate Alien, and this was because he had an Ultimate form. In Omniverse, Ben has three fire aliens; Heatblast, NRG, and Swampfire, but Ben favors the first two. So Swampfire is out of the equation for significant appearances.
