Well, I suppose he's characterized as being more gullible and honest than a show off. But I get the feeling if given the chance (or made extremely drunk) he'd be a bit of a show off. I've always pictured him as a strong person (and honestly, I think he's kinda hot in his own way). So, I drew him as such here

Now, I realize that this looks a tad weird. To make a Sonic character look good as a furry, it takes someone with amazing skills and abilities with colors and lighting. They have to know what they're doing, and try tirelessly to make the image work since you're taking a small little character and expanding it

I have fulfilled absolutely none of these requirements. Also, I am terrible a muscles :P

I just did my own thing, and this is what happened. So, take it as you will~ x3
