Now here's a nice one!
Top Heavy is starting down the right path with this shirt. Sonic in subdued colors, and a stylish Japanese name beside him. He is also bordered with red, and there is a Japanese Sonic X logo beside him, and on the sleeve (in orange) The art may be stock from X, but it's presented in a subtle manner that does not just seem "slapped on for the kids".
**This is a reasonably sized shirt! It is never "too tiny" and comes in sizes likely to fit you, be sure to pick it up if you want it!

The red is actually a neat, shiny reflective paint, but it does not show the luster in the photos.
