Echo Echo is the Infinity's DNA sample of a Sonorosian from the planet Sonorosia in Bryce Bowman: Origins.


Because his true form is made of living sound waves, Echo Echo's appearance is actually a small, white containment suit made of silicon, making his body a living amplifier.

One of his most noticeable features is a square appendage resembling an MP3 player behind his back with a port on it, decorated with a 10 symbol and what looks like cassette tapes on his lower legs. The green circle-shaped indents on the back of Echo Echo's hands are sound holes, and the inside of his mouth is also green with lines that give it the appearance of an amplifier. He also wears headphones so he would not be hurt by his own sonic screams.

Transformation Sequence

White silicon-like skin stretches from the Infinity and covers Bryce's face. His ears grow into a headphone shape and his eyes glow green. His body shrinks, then Echo Echo poses.


Echo Echo was unlocked by Bowman 10,000 in his title episode Bowman 10,000 (Episode).

In Change of Plans, Echo Echo defeated a group of Esoterica with the help of Gwen and Kevin.

In Nemesis' Revenge, Echo Echo was almost defeated by Ultimate Diamondhead before going ultimate himself.

Powers and Abilities

Echo Echo can scream at audible to ultrasonic frequencies capable of overloading machinery, shattering steel and stopping projectiles in mid-flight.

Echo Echo has the ability to duplicate himself, but the clones are not linked to each other in any way, allowing entire groups to be knocked out without harming the rest.

By combining these two aspects, Echo Echo can create a wall of sound, where he and his clones can redirect projectiles back to their source by bouncing them off of strategically placed clones.

Echo Echo can create an echo chamber, where his clones attack from all directions and keep screaming until the target is knocked out or defeated.

Echo Echo can detect vibrations in the ground.

Echo Echo's sound holes help him resonate.

Using his sonic screams, Echo Echo can locate objects/people, giving him the ability of echolocation.

Echo Echo can channel vibrations to enhance his screams.

Echo Echo can transmit sound waves through speakers.

Echo Echo can use his sonic screams to create a force field.

Echo Echo is quite agile, as he is capable of jumping exceptionally high.

Echo Echo seems to have more strength than his size suggests.


Echo Echo has a fragile body that can easily be destroyed in battle.

Echo Echo's sonic screams can easily hurt his teammates' ears.

Echo Echo has a limit to the number of duplicates he can make, which depends on the amount of energy he has access to.




  • According to Dwayne McDuffie, Echo Echo has headphones so he isn't hurt by his own sonic screams.
  • His voice is low-pitched and electronic; he tends to pause in between words. He sounds like he did in his first appearance in Ben 10 Returns.
