Cookie Run: Kingdom's library of characters is constantly increasing given the massive fanbase of its parent game, Ovenbreak. Almost all new characters added via updates are cookies imported from the latter to Cookie Run: Kingdom.
Cotton Cookie's addition to the game was highly anticipated, given she is the first "healer-damage dealer" cookie in the game. She was released alongside Frost Queen Cookie in the first half of the Frost Witch and the Lantern in the Snow update.
The Cookie's in-game description reads:
The release of Frost Queen and Cotton Cookie at the same time was not a coincidence.
According to the Frost Crystals Event story, Cotton Cookie's closest friend Sherbet Cookie was reduced to a snowy hazard, by the order of the Frost Witch. Her friend's current form was unstable for her to face. Cotton Cookie's plight was ended by Frost Queen Cookie, as she shielded Cotton Cookie and allowed her to be with her friend in his last moments.
Post this, Cotton Cookie and Frost Queen grew close, as Frost Queen was also afflicted with the same disease that proved fatal to Sherbet Cookie.
Cotton Cookie is an Epic Support class cookie currently considered to be one of the most powerful characters in the game. Her ability to heal, attack, and support her teammates simultaneously makes her ideal for anchoring most team compositions.
Cotton Cookie's "A Warm Light" ability has quite a bit of utility packed into it. Firstly she shines her lantern, whose warm light heals all allies and summons. Secondly, she also summons a herd of sheep who charge at the enemy and deal AoE damage and stun the enemy before retreating.
For the duration of her casting, all allies' ATK power is increased by 75%.
