Swampfire (Earth-68)

This is the version of Swampfire that appears on Earth-68, the universe owned by Dioga beta. Swampfire is the Omnitrix's DNA sample of a Methanosian from the planet Methanos. His Ultimate Form is Ultimate Swampfire.

Appearance
Swampfire is a humanoid, plant-like alien that has an overall green and black colored body, mostly with a flame-patterned head and root-like feet, seemingly holding rocks. Also, his shoulders and head have red petals. Swampfire is taller than an average human and has a distinct rotten stench that worsens with heat. His voice is very stuffy and nasally because he has no nose. Swampfire wears the Omnitrix/Ultimatrix symbol on his chest.

In John Smith 10, he has his UAF appearance until Omniverse, where he gains his First Omniverse design.

Powers and Abilities
Same as canon Swampfire in UAF.

Weaknesses
Same as canon Swampfire.

 * Swampfire is one of my least favorite aliens. Therefore, he doesn't appear in as many series.
 * There are no plans for him to gain his Second Omniverse appearance in John Smith 10. There are plans for it to appear in other series.
