Ben 10 (Saga 02) (2008) S01E01 Ben 10 Returns Pt. 2 Echo Echo Transformation

Echo Echo can scream at audible to ultrasonic frequencies capable of overloading machinery, shattering steel, redirecting projectiles in mid-flight, destroying multiple Laser Lances at once if concentrated for enough time and even damaging Taydenite at the right frequency. However, technically speaking, they are not as powerful as a Loboan's sonic howls. Echo Echo's sound holes help him resonate. Echo Echo has the ability to create an unknown number of exact duplicates of himself. These clones have all the same powers; act so harmoniously that they can finish each other's sentences; and are not linked to each other in any way, and are thus not disturbed by each other being knocked out or inflicted pain. Even if entire groups of his clones are destroyed, Echo Echo can survive as long as at least one of him is still intact. Echo Echo can create an echo chamber, where his clones attack from all directions and keep screaming until the target is knocked out or defeated, as demonstrated in his fights with Helen and Ultimate Kevin. Echo Echo can also use this ability to make objects explode. Echo Echo can use his sonic screams to create a force field. By combining his sonic screams and his self-duplication, Echo Echo can create a wall of sound, where he and his clones create a gigantic sound wave that can deal massive damage to his opponents and structures. Echo Echo can levitate in the air. Echo Echo seems to have more strength than his size suggests, as he can carry a power coupling completely on his own, and kick off the trunk door from the Mark 10 with one foot. With the help of multiple clones, Echo Echo can throw a Plumber Ship about a meter, carry a Murk Gourmand, and hold his own against larger opponents such as the mechanical dragon, a Highbreed, and Ultimate Kevin. Echo Echo also appears to be rather durable, as he and his clones were able to withstand.
