Some say it was made by the god of mischief Loki, some say it was voodoo. What we truly know is that every wearer of this mask is granted the power to turn their wildest dreams into reality, at the cost of their own sanity. The mask grants you the power known as "Toon Force", you are basically a living cartoon without care about physics. You could get splatted in the ground and get back up with no injuries, explode, and come back. You can take any weapons and tools from your pocket, even though they should not be there, and many more things you could do which are only limited by yourself.
Your only weakness is if your mask is taken from you and every action you take, must be comical.
Even though you lose your sanity while wearing the mask, your morality and personal rules remain, if you have them.
You can choose to have a movie, comic, or cartoon mask. Only the comic mask doesn't affect other people with toon force.
