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. But now he has blue metallic skin, has 15 blue, removable speaker-like components attached to his body, an overall rounded design, and with longer arms and legs. There is also no sign of his power control pack, or the cassette-like tapes on Ultimate Echo Echo. 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.

Abilities
Like Echo Echo, Ultimate Echo Echo controls the power of sound. But Ultimate Echo Echo does not duplicate himself. He has evolved to expend much less energy by sending out the floating amplifiers at his joints to project sonic blasts which at full force can shatter steel and it can be used as a boomerang. Ultimate Echo Echo also has the ability to fly by projecting sound waves around himself, and can even fly fast enough to create a sonic boom. In TKO, it shows he can create forcefields out of sonic waves.

Ultimate Alien
He makes his first apearance in Map of Infinity where he is used to fight off the temple gaurdians (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|300px|right
