Atlus is providing a web page for sharing people's custom made heroes: http://www.3ddotgameheroes.com/hallofheroes/p-t.html
Let see who will make the first Jack Frost hero.

I wonder if these will work on the Japanese version?  Only one way to find out!   (but I'm too lazy)

it's not just p-t ... it's that only one or two people have uploaded any at the time GI tried to link them, which I expect the OP found the link at.
 
Speaking of finding a Link, where's that repository full of Japanese made heroes? It's probably in one of Linkyshinks' threads. 
 
So who's up for the inevitable contest to see who can make the best Giant Bomb? Is there a way to make the sword look like a tongue?
