Disclaimer
As you may or may not already know, the characters on this site are based on Nintendo characters.  All I have done is spruced them up a bit and given them different names and personalities (more so the drawings rather the sprites). Therefore, Half the credit for these characters goes to Nintendo, and the other half goes to GEOWeasel.  This is NOT copyright infringment since I'm not using them to get money.  Even still, the characters on GEOWeasel are not yours for the taking!  And don't even give me that crap that you created the character before me.  I won't lie, this site was started in 2002, but these characters date back to 1999.  Also, several characters were used in the original Super Nario Bros. several years ago, with permission from their creator, Jay.  These characters are Jay, Bill, Fred, Dr. Donez, Citrus Man, and Jay Respo.  But Bill and Dr. Donez are als copyright to Nintendo and Fred is Copyright to hal Laboratory. If you DO take my characters, you WILL regret it for the rest of your career on the internet and I will see to it myself!

So in a nutshell, here is the breakdown:
-Mario, Luigi and all related Characters are copyright Nintendo.
-Nario, Big Weas, Jim, Duigi, and all related characters belong to me with copyrights to Nintendo.
-Bill, Fred and all related characters belong to Jay of NC, but are copyright Nintendo and Hal Laboratory.
-Hammer Guy and all related characters belong to Hammer guy with copyrights to Nintendo
-Don't take any of these characters because they ARE under copyrights

Thank you and have a nice day.
