Ivan Chillski

Ivan Chillski, known as Ivan Coolisky (イワン・コオリスキー) in Japan, is a character from MegaMan Battle Network 4. He is from Sharo and his NetNavi is ColdMan.EXE. He is rude and hates the heat. He would probably be much cooler if he took off all the extra clothes he's wearing. Based on his name, Ivan probably comes from Russia.

Personality
Ivan,in the games, is very rude and pushes people in his way. He is selfish and is willing to freeze over Sharo and Netopia in order to make himself more comfortable. He also seems to lack common sense, seeing as he could make himself more comfortable if he took off his coat. Ivan also hates the heat and is terrified when he is sent to a prison in NetFrica.

MegaMan Battle Network 4
He appears in the Red Sun/Blue Moon Tournament as Lan's opponent. He complains of the heat and decides to do something about it. Ivan uses ColdMan.EXE to unleash a snowstorm on Netopia but stops when Lan and MegaMan.EXE tell him to. So he goes back to Sharo and does the same thing by creating snow viruses in weather controlling satellites. The temperature drops too low even for Sharo. Lan has to dig up snow, defeat viruses and sacrifice flame chips to stop the blizzard before the temperature is too low to handle. After finishing the mess, Lan and MegaMan.EXE fight verbally before NetBattling. Ivan and ColdMan.EXE lost and were arrested for hacking the satellites and sent to a prison in Netfrica (to Ivan's despair).

Rockman EXE Stream
Ivan is a renown engineer who specializes in data compression. He is angry when his latest project is disapproved and Slur gives him Asteroid ColdMan.EXE to get revenge. He gets ambushed by Chaud and Rauol in their Disco villain outfits. ColdMan.EXE is deleted by Crossfusion Chaud and Ivan is subsequently arrested.
