ColdMan.EXE, known as FridgeMan in the English anime, is a NetNavi operated by Ivan Chillski (Ivan Coolisky in Japan). In MegaMan Battle Network 4 Red Sun, he is Lan's opponent in the Red Sun Tournament. ColdMan hacks Netopia's Network, creating a blizzard because Ivan was too hot in the temperate climate (coming from Sharo, based on Russia). MegaMan.EXE went after him and told him to stop. He later goes to Sharo and does the same thing with the 4 weather control satellites. AFter fixing them, Lan and MegaMan Netbatle him and win.
