ColdMan is one of the opponents that Lan Hikari and MegaMan.EXE face in The Red Sun/Blue Moon Tournament. ColdMan hacks Netopia's network, creating a blizzard because his operator Ivan was too hot in the temperate climate (coming from Sharo, a winter country). In order to stop the blizzards, Lan and MegaMan pursue him. After confronting him the Netopia area, he relents and restores the Netopia system to normal. However, Ivan and ColdMan go back to Sharo and cause a blizzard there which leads to a blizzard in Netopia. Lan and MegaMan then travel to Sharo to stop the four weather control satellites causing the blizzard. After fixing them, Lan and MegaMan meet Ivan and ColdMan in the Blue Moon arena and defeat them.
ColdMan is a Darkloid, under the leadership of ShadeMan.EXE. But he turns on him when LaserMan.EXE defeats him. ColdMan, SwordMan.EXE, BrightMan.EXE and StarMan.EXE team up to cause trouble on the Net when MegaMan.EXE is badly injured by Dark ProtoMan. However, Raoul, ThunderMan.EXE, Raika, and SearchMan.EXE fight them. Although they were at a disadvantage with four versus two, they manage to drive them off by deleting BrightMan. Later, ColdMan and SwordMan go to a desert with a huge castle in it to enlist the help of MistMan.EXE. While searching, they get lost with Lan and Mayl. After finding MistMan, ColdMan and SwordMan are deleted by him in a battle. During the climax of the series, all of the Darkloids are revived by Dr. Regal as a distraction for the NetPolice. He is deleted by Searchman.
An Asteroid version of ColdMan is given to Ivan Coolinsky by Slur. Together, they kidnap navis all over the world by using Ivan's compression program. Chaud and Raoul then manage to trap them, but Ivan uses a Dimensional Chip to make Coldman come into the real world. He is deleted by CF-ProtoMan and Ivan is later arrested.
