Ultimate Echo Echo

Ultimate Echo Echo is the evolved form of Echo Echo.

Appearance
Ultimate Echo Echo looks nearly nothing like Echo Echo. 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 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. Ultimate Echo Echo wears the evolved Ultimatrix symbol on his chest.

Powers and Abilities
Like Echo Echo, Ultimate Echo Echo controls and manipulates the power of sound. When Echo Echo has duplicates around and one 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 ability to fly and can even fly fast enough to create a deadly sonic boom and probably open a hyperspace window. He can also 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 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. He can generate some sort of atmosphere, because he is able to use sound abilities in space''. ''He possesses enhanced strength.

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

Trivia

 * Ultimate Echo Echo's voice is nothing like Echo Echo's, unlike Ultimate Swampfire's.
 * 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.
