By the way mate, it's not a good idea to ask where to download warez here, it's against the forum rules, tell you what, I'll make one now and post it here for you in a few minutes.
Edit: The J, here's what I made for you, sorry it's not all that good, I only spent a few mins on it, if there's anything you want changed, just ask here and I'll see what I can do.
Enjoy, remember if you don't like something about it, feel free to let me know and I'll change some things. I stuck to Goku because by looking at the sig you made, he's the char you wanted, same with the colour, I went purely on the appearance on the sig you made.
