The Sentient Ultimate Swampfire was trapped in the Ultimatrix as Ultimate Swampfire until he was freed by Azmuth and Ben.
Appearance
The sentient Ultimate Swampfire looks just like Ultimate Swampfire, except he has red eyes and lacks the evolved Ultimatrix symbol on his chest.
History
In The Ultimate Sacrifice, the sentient Ultimate Swampfire, along with the other Ultimates, convinced Ben to commit suicide so they could be free. Ben tried to, but was stopped by Azmuth, who freed and sent the Ultimates to a planet where they could live in peace.
Powers and Abilities

Azur Pyrokinesis
The sentient Ultimate Swampfire can ignite napalm in his arms to generate blue-colored flames. These flames are about three times hotter than a regular Methanosian's, as they can melt through a brick wall[1] and blast apart a Petrosapien's shard projectiles.[2]
The sentient Ultimate Swampfire can produce a larger and stronger blast of fire when he puts his hands together. He can also propel himself underwater and in the air, the former further indicating that he can breathe underwater.[3]
The sentient Ultimate Swampfire is more resistant to damage than a regular Methanosian.
The sentient Ultimate Swampfire has lethal fire bombs on his arms which he can throw as weapons.
The sentient Ultimate Swampfire can shoot blue projectiles from his hands that can multiply into small blue gas bombs that explode on impact.[3]
The sentient Ultimate Swampfire retains a regular Methanosian's abilities to generate seeds and vines.
The sentient Ultimate Swampfire seems to be a lot faster than he looks, as seen when his Ultimatrix counterpart snuck up behind Eon so fast that he was unable to notice him.[4]
Weaknesses
The sentient Ultimate Swampfire is vulnerable to electricity, such as that generated by an Amperi.[1][5]
Like other organic beings, the sentient Ultimate Swampfire is vulnerable to being aged to dust by the time rays of a Chronosapien or a Chronian.[4]
Unlike regular Methanosians, the sentient Ultimate Swampfire cannot regenerate. However, Matt Wayne thinks otherwise, as he believes it is a trait that natural selection would favor.[MW 1]
