Hambonetaru-Chan is played by an evil American marketing executive testing the hypnotic effect of big shiny-eyed anime cute and fluffy things on America's youth.  His current project is a twisted mix of Hamtaro and Pikachu.  At one point he agreed to sponsor Elf Only Inn to cover the rising server costs and his company forced everyone to change their character images into proper anime ones.  That was before he realized that the 90's were over, and there was no money to be made off of free Internet chatrooms. 

After getting fired for an ill-advised marketing scheme involving PokeCrabs, he has returned to working on more terrible anime knock-offs and writing those gosh-darn clever Truth.com anti-smoking ads.
