Icelee has white skin and wears a long, white cloak. She also has a third eye on her glabella.
Icelee acted as a spy of sorts, transforming into a girl named Hoshi-kko to get information on Takeshi Yamato. She was deployed along with Herodenia III by Witch Iguana to also take out Rainbowman. Following Herodenia III's demise, Icelee tookover the operation and tried to kill Rainbowman with her Die Die Gang soldiers, although they were all defeated and Icelee was forced to retreat. She then disguised herself as a young girl and was found by a young boy and his grandma who thought she was lost in their barn. Icelee then later reappeared at night time where she tried to chase down Rainbowman, however Daiba Datta knew what she was up to and then blocked her path by creating a giant boulder in her way. Icelee then retreated back.
Icelee then later hid out at the village temple for some more time until Rainbowman was vulnerable. When the boy's grandma instead came in to her trap, Icelee then revealed herself and also fought the grandma, but she soon defeated and then killed the grandma with her icy knife. Rainbowman then showed up and the two fought for a while, with Icelee throwing everything she had at Rainbowman. After trapping Rainbowman in an icy prison, Rainbowman then used Dash 5 and destroyed her icy barrier, then used Dash 5 to destroy Icelee. Icelee was cracked apart and then soon vanished, defeating the ice witch for good.
