A Monster in Paris- Character idea number 3

I've been trying to figure out this strange anatomy.

The third OC for the comic. Kiki, a Giant and ride-able Hissing cockroach.

And for just for kicks, he can whistle. being so small a human ear probably couldn't pick up the high frequencies and thus sounding like a hiss, but on a large scale you can hear the whistle! Xd I have too much time on my hands....

a fighting insect! [link] charging like a bull!
found this vid and you can see the color better and hear him hiss![link]
