Well here's my second design of Echo Echo. Here's the first:[link]
I think my first design is still cool but when I looked at alot of my aliens and I thought to myself alot of them have shapes that are too humanoid so I decided to redesign a few of them.
I like Echo Echo's Omniverse design and the only thing I hate are his bug eyes, they really creep me out sometimes. So I took his omniverse design and my redesign and combined them to make this. I also decided to add a bit more black into this design to have the color scheme of OS Upgrade, and the reason for this is that my version of Echo Echo is a cousin species to Galvanic Mechomorphs called Galvanic Sonorosians.
I'd have to say my favorite part of this Echo Echo is his chest speaker that he uses for sonic blasts like Iron Man uses his unibeam and if he makes a sound field around himself and focuses soundwaves in certain areas he can create solid sound duplicates.
