Ultimate Echo Echo is the evolved form of Echo Echo.


Ultimate Echo Echo has blue metal skin, 15 blue, removable speaker-like components attached to his body, an overall rounded design and longer arms and legs. Also, Echo Echo's power control pack is replaced with a marking resembling a cassette tape. His voice is more robotic-sounding, similar to a speaker. His mouth doesn't move when he speaks, but he can open it. Ultimate Echo Echo is about Ben's height and has stumped feet.

Ultimate Echo Echo wears the evolved Ultimatrix symbol on his chest.

Powers and AbilitiesEdit

Like Echo Echo, Ultimate Echo Echo manipulates the power of sound, but he can also send out the floating amplifiers dotting his body to project incredibly strong and powerful sonic blasts, which at full force can knock someone out and shatter metal, iron and steel with relative ease.

Ultimate Echo Echo also has the ability to fly and can fly fast enough to create a deadly sonic boom and probably open a hyperspace window, since he has been confirmed to be faster than Jetray and Jetray can go into hyperspace. He can create force fields out of sonic waves that are strong enough to contain a blast from a mini-nuclear bomb. He was also able to survive a blast from said bomb, but was damaged.

The sonic discs he produces can multiply, letting him use an exceedingly deadly move called Sonic Doom, where his discs surround the enemy and fire a full sonic blast. Sonic Doom is shown to be strong enough to knockout and potentially kill Kevin, who at the time had absorbed Ben's powers again. He is able to fire sound waves from the discs when they are still on him. He can generate some sort of atmosphere, because he is able to use sound abilities in space. He possesses enhanced strength.



Ultimate Echo Echo is made of metal, so he can be magnetized. Ultimate Echo Echo lacks Echo Echo's self duplication.

Ben 10: Ultimate AlienEdit


  • Ultimate Echo Echo and Ultimate Spidermonkey are curently tied for the most used Ultimate, at 8 times each.
  • Out of the 3 most drastically changed Ultimate (Swampfire, Spidermonkey and Echo Echo), Ultimate Echo Echo seems to be the most drastically changed Ultimate for these reasons:
    1. Ultimate Echo Echo's voice is nothing like Echo Echo's, unlike Ultimate Swampfire's.
    2. Ultimate Echo Echo doesn't retain any phenotype minus his eye color, whereas Ultimate Spidermonkey retains his purple-blue hair. He has no sign of anything left from Echo Echo unlike Swampfire and Spidermonkey who still have the same feet or color scheme.
    3. Ultimate Echo Echo's ability to multiply has been completely rejected by his geneology and replaced with sonic discs. However he retains his Sonic Screech.
  • Ultimate Echo Echo has 4 fingers, but in the Cosmic Destruction art of him, he has 5.
  • When Echo Echo has duplicates around and one goes Ultimate Echo Echo, the duplicates turn into sonic discs.
  • In the ultimate form's first appearance in Map of Infinity, Kevin asks Ultimate Echo Echo why his name wasn't "Ultimate Echo Ultimate Echo", a joke on how the original Echo Echo's name consists of "Echo" repeated.
  • In The Enemy of My Enemy, it is revealed that Ultimate Echo Echo can survive in the vacuum of space.
  • So far, Ultimate Echo Echo is the Ultimate Form that was used by Ben the longest (Map Of Infinity). However, this was only because he was on a planet where he would die without protection.
  • Ultimate Echo Echo does not have a mouth that moves when he talks like his normal form does, although in The Perfect Girlfriend Ultimate Echo Echo nearly choked on the nanochips.
  • According to Cartoon Network's site, Ultimate Echo Echo can duplicate himself like Echo Echo, this is wrong.
  • In Map Of Infinity, a coloring error shows Ultimate Echo Echo's fingers are black when he transforms, but were blue when he takes the sonic discs off and back to black when he is shown throwing them and his shoulders were blue then black.
  • Ultimate Echo Echo is in the cartoon network game TKO. His special moves are sonic disc and sound barrier and his super move is echo chamber.
  • Recently, Ultimate Echo Echo was added as a new alien for Cartoon Network's Ben 10 Alien Force: Game Creator.
  • Ultimate Echo Echo is one of the three ultimate aliens on Ben 10 Game Creator.
  • Ultimate Echo Echo is the last alien used by Ben in season 1 of Ultimate Alien.
  • Just like how Echo Echo made up "Wall of Sound", Ultimate Echo Echo made up "Sonic Doom".
  • Ultimate Echo Echo is made of metal, as seen when Ultimate Kevin magnetized him in Absolute Power.
  • When Ben transformed into Ultimate Echo Echo in Viktor: The Spoils, his voice sounds different.
  • During all the transformations of Ben turning into Echo Echo to Ultimate Echo Echo, Ultimate Echo Echo never goes back to Echo Echo again, he goes straight back to Ben except in Greetings From Techadon and in The Perfect Girlfriend
  • Ultimate Echo Echo has a similarity to the Batman Beyond villain, Shriek with powers and looks.
  • Ultimate Echo Echo's voice is similar to that of the Decepticon Soundwave in Transformers.
  • Ultimate Echo Echo is the first Ultimate to almost kill someone.
  • Ultimate Echo Echo has an exosuit in Project Exonaut.
  • Ultimate Echo Echo is shown to be able to open his mouth and he has lungs in The Perfect Girlfriend.
  • The animators rarely show Echo Echo's ultimate transformation, due to their scale size changing so drastically that the Ultimatrix on Ultimate Echo Echo is higher than Echo Echo's height. Therefore, it messes up the outward ultimate transformation.
  • Ultimate Echo Echo is November's Alien of the Month. Ultimate Echo Echo is the only alien that still had the intention to kill an enemy who was at the moment, defeated, as in Absolute Power: Part 2, where he nearly kills Ultimate Kevin and Double or Nothing, where the same Albedo occurs. On both occasions, Gwen stops him. In this way, it's possible that like Rath gets angry, Ultimate Echo Echo has the need to do his worst at times, normally when he's angry at someone.
  • Ultimate Echo Echo's voice has changed a lot in some episodes. In some episodes his voice can appear robotic, while in some it can appear softer than usual.
