These three characters are concepts of a character I had in mind. The first character was a really rough sketch to get an idea of what it may look like. In wanted a grappling hook and sword for tools. The second one was more focused on the sword and I kept in the eye, because I wanted it to glow when it turns into the giant version (if I have time and think it is worth putting it in). The third one went the complete opposite of the second look, this time going for a more childish/casual look.
The character I am probably going to make is a mixture of the 2nd and 3rd look.
