The sentient Ultimate Echo Echo looks just like Ultimate Echo Echo, except he has red eyes and lacks the evolved Ultimatrix symbol on his chest.
In The Ultimate Sacrifice, the sentient Ultimate Echo Echo, along with the other Ultimates (apart from Ultimate Wildmutt and Ultimate Way Big), convinced Ben to commit suicide so that they could be free. Ben tried to, but was stopped by Azmuth. They were freed by him and sent to a planet where they could live in peace.
Powers and Abilities
Like regular Sonorosians, the sentient Ultimate Echo Echo can release sonic screams and ultrasonic waves from the Sonic Disks on his body. These sound waves are powerful enough to throw Ultimate Kevin through several buildings at once, damage a Petrosapien, and paralyze an Opticoid, as demonstrated with his Ultimatrix counterpart.
The sentient Ultimate Echo Echo can fly by using sound waves.
Because his appearance is a containment suit,[DJW 1] the sentient Ultimate Echo Echo can survive in the vacuum of space. He can also produce airwaves, as he is capable of using his sonokinetic powers while in space as well.
The sentient Ultimate Echo Echo manipulates the power of sound, but he can also send out the Sonic Disks on his body to project powerful sonic blasts, which can knock someone out, destroy projectiles or even a military tank, with relative ease.
The sentient Ultimate Echo Echo can multiply the Sonic Disks once they have separated from his body, creating as many as needed.
The sentient Ultimate Echo Echo can use his Sonic Disks to use an exceedingly deadly move called Sonic Doom, where his discs surround the enemy and fire full sonic blasts. This move is powerful enough to subdue Ultimate Kevin, who had managed to win almost every previous battle he had got into.
The sentient Ultimate Echo Echo can be suffocated if a large amount of matter enters his lungs.
