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 metal skin, 15 blue, removable speaker-like components attached to his body, an overall rounded design, and longer arms and legs. Also his power control pack is replaced with a a marking resembling a cassette tape. 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 stumped feet.

Powers and Abilities
Like Echo Echo, Ultimate Echo Echo controls and manipulates the power of sound. He can duplicate his discs, but not himself.When Echo Echo has duplicates around and he goes ultimate the duplicates turn into sonic 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 knock someone out and 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 was also able to survive a blast from said bomb, but was slightly damaged.

The sonic discs he produces can also multiply, letting him use an exceedingly powerful move called Sonic Doom, where his discs surround the enemy and fire a full sonic blast, with the potential to be fatal.

He is able to fire sound waves from the discs when they are still on him, demonstrated when he blasted Kevin through several buildings at once with the discs on his hands.

Apparently, he can generate some sort of atmosphere, because he was able to use sonic abilities in airless space (sound needs air to travel through in order to work) in the Enemy of my Enemy.

He possesses some degree of super strength as seen in Map of Infinity when he helped Kevin lift a heavy stone door, before changing to Four Arms.

Ben 10: 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.thumb|right|188px

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 Ultimate Kevin, and he actually did defeat Kevin making Ultimate Echo Echo one of Ben's strongest aliens.

His fourth appearance was in Viktor: The Spoils, where he was used to stop the surface-to-air missiles attacking the jet. This was the first time he was seen evolving.
