Ultimate Echo Echo

Ultimate Echo Echo is the evolved form of Echo Echo in Ben 10: Ultimate Alien. Ben first became Ultimate Echo Echo in Map of Infinity to help his friends get through the traps at the temple.

Appearance
His appearance is now more robotic than his previous form. he is now he has blue metallic skin, 15 blue, removable speaker-like components attached to his body, an overall rounded design, and longer arms and legs. There is also no sign of his power control pack, and a cassette-like tape is on Ultimate Echo Echo's back. His voice is now more robotic-sounding, similar to a speaker. His mouth doesn't move when he speaks. Ultimate Echo Echo is also taller; about Ben's height, and has no feet; just legs.

Powers/Abilities
Like Echo Echo, Ultimate Echo Echo controls and manipulates the power of sound. However, he cannot duplicate himself, though he can duplicate his discs. He has evolved to expend much less energy by sending out the floating amplifiers at his joints to project incredibly strong and powerful sonic blasts, which at full force can shatter metal, iron, and steel with relative ease. Ultimate Echo Echo also has the power and ability to fly by projecting sound waves around himself, and can even fly fast enough to create a deadly sonic boom. He can also create invisible force fields out of sonic waves that are strong enough to contain a blast from a mini-nuclear bomb. He is also able to survive a blast from said bomb, but was banged up a bit. The sonic discs he produces can also multiply, letting him use an exceedingly strong and powerful move called Sonic Doom, where about two-dozen (twenty-four) discs surround the enemy and fire a full sonic blast, sometimes being fatal. He is also able to fire sound from the discs when they are still on him, demonsrated when he blasted Ultimate Kevin through a building with the discs on his hands.

Ultimate Alien
He makes his first appearance in Map of Infinity where he is used to fight off the Necrofriggian temple guardians (Big Chill's species). Later in the episode he is seen flying a few times to avoid the acid and other traps. He also helps them defeat the two headed fire ice dragon, which was easy for Ultimate Echo Echo. When they reach the map they have to lift the wall so he then turns into Four Arms.

He appeared again in order to stop a nuclear fusion grenade from going off in The Enemy of My Enemy. He also appeared in Absolute Power: Part 2 to stop Kevin, making Ultimate Echo Echo one of Ben's strongest aliens.

Trivia

 * Ultimate Echo Echo has 4 fingers, but in the Cosmic Destruction art of him, he has 5. The reason for this thumb|300px|rightis so far unknown.
 * It is revealed on the Cosmic Destruction site that Ultimate Echo Echo can fly faster than Jetray.
 * Kevin asks him why his name wasn't "Ultimate Echo Ultimate Echo", a joke on how the original Echo Echo's name includes "Echo" repeated twice.
 * Unlike his regular form, he cannot duplicate himself. (As confirmed on the Cosmic Destruction site and by Dwayne McDuffie).
 * In The Enemy of My Enemy, it is revealed that Ultimate Echo Echo can survive in the vacuum of space.
 * So far, he is the Ultimate Alien who has been used by Ben the longest. However, this was only because he was on a planet where he would die without protection.
 * Originally his voice was going to be less robotic than Echo Echo's, but it was later changed to make it a deeper version of Echo Echo's.
 * Cartoon Network's site wrongly shows that Ultimate Echo Echo can still duplicate himself.
 * In the first episode he appears in, a coloring error shows his 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_TKO.jpg
 * He is in the cartoon network game TKO.
 * Recently, Ultimate Echo Echo was added as a new alien for Cartoon Network's Ben 10 Alien Force: Game Creator.
 * He is one of the few aliens on Ben 10 game creator.
 * He is the last Ultimate Alien to appear.
 * Ultimate Echo Echo might be the one of the strongest ultimate aliens, because Ultimate Swampfire and Ultimate Cannonbolt were beaten by Aggregor who was later beaten by Kevin who later defeated Ultimate Humungousaur but then was defeated by Ultimate Echo Echo, though it may only be because of the fact that Ben was intent on finishing (killing) Kevin instead of just defeating him, his choice of Ultimate Alien could have come from the fact that Ultimate Kevin had no alien to defend himself from sonic attacks, as Chromastone cannot absorb that.
 * Ultimate Echo Echo is the last alien used by Ben in season 1 of Ultimate Alien.
 * When Echo Echo transforms into Ultimate Echo Echo with duplicates in existence, the duplicates transform into sonic discs.
 * Just like with his normal form made "Wall of Sound", he made up "Sonic Doom".
