The first character in a while that I actually had a name for before finishing this. Sonar is a skilled sniper/bounty hunter and what not but the odd thing is that he is blind which leads to problems and he relies on echolocation and sonar to see. One antenna (the left) on his helmet lets out a powerful frequency and sometimes sounds (The sounds being better for specific areas) and the other (right) picks up the sounds and sounds of things not even produced by the sonar, allowing him to pinpoint the locations of things and form a picture of things in his head. (There is a slight problem of him hitting the wrong target which is why he prefers to only stun the targets) (I feel like his name should be Echo or at least a nick name or something...)
I thought it would be interesting to have some blind archer or ranged weapon character so ta-da I guess? I don't really know of any examples of this in media, shows, or stories but I feel like it would be an idea used before. It is also possible to tap your keyboard or the screen...
