(I'm going full O.R.Ash on this one) For my take on Echo-Echo, I kept the same power traits he originally had in the series like Duplication, The Squishy Body and his Super Sonic Screams. But I also gave him new abilities, everytime Echo-Echo get squashed or stretched, he'll blow up with his Super Sonic Screams, but he can also recover from that, I call that The Marshmallow Bomb. And for his 2nd New ability he can generate soundwaves to any part his body like his arms and legs, his head and even his whole entire body, I call that Soundtrack Plow. And for his 3rd ability, he can receive radio transmissions, I call that Walky-Talky
