Ben 10 Ultimate Alien has a whole new take on the aliens Ben Tennyson is able to transform into. In fact, it’s an all new Ultimate take! Using the power of the Ultrimatrix, sort of an updated Omnitrix, many of Ben’s original forms have since evolved into ultimate versions of themselves. We’ve seen what’s happened to Humongousaur and Cannonbolt, and here’s Ultimate Swampfire; a more wood-like form with three gooey shells containing his blue flames. Ultimate Swampfire appears a bit stouter than original Swampfire, but certainly more powerful – able to create a blue-flame nova explosion, fire bombs, shoot nova blast, blue fire tornadoes, regenerate, and still control plant life. We first saw Ultimate Swampfire in Alien Force’s “The Final Battle”; Ben’s first Ultimate transformation.
