Costume

Costumes are a recurring feature in the Cookie Run franchise. In Cookie Run (LINE), Costumes were only cosmetic and only present during Halloween Parties. In Cookie Run: OvenBreak, Costumes provide a small bonus effect in addition to the cosmetic changes, and are collectables purchased with Rainbow Cubes at the Costume Shop or Costume Gacha. In CookieWars, some units are based on Costumes from OvenBreak or introduce new Costumes, and function as stronger versions of the original Cookie. CookieWars was the first game to feature separate Costumes for Pets.

History
Costumes made their first appearance in the Halloween Party 2014. These costumes altered the appearance of the Cookies for Halloween, and were purely cosmetic. Once the Halloween Party 2014 event ended, the Cookies reverted to their normal appearances. Subsequent years, Halloween Party 2015 and Halloween Party 2016, would continue this trend by returning the old Costumes and creating new ones for the Cookies released during the gap between the events.

In Cookie Run (Kakao), Kumiho Cookie and Rebel Cookie were time-limited Cookies who had three different Costumes in addition to their Halloween Costumes depending on when they were obtained, a feature unique to them.

Costumes would make another appearance as a feature in Cookie Run: OvenBreak with an update on March 24th, 2017, with the release of Hero Cookie's First Suit: SCV1 as a limited purchase item or Invite Event. More Costumes would be added for the other Islands of Memories and in batches in Halloween Updates and other updates, with these Costumes now purchasable with a new currency, Rainbow Cubes. Starting with Cinnamon Cookie, newly added Epic Cookies always release with a Costume, except for Purple Yam Cookie and Milk Cookie, which got their Costumes at the next Grand Champions League. Cookies who receive a Magic Candy or a major buff after their release often get a Costume as part of the update as well, even if they already have a Costume.

Types of Costumes
In Cookie Run: OvenBreak, costumes come in five rarities: Common, Rare, Epic, Super Epic, and Legendary. Additionally, some Costumes are Limited, meaning they were only available for a limited time. Before the addition of the Costume Gacha, far more Costumes were Limited, but they were made available and reclassified as Epic or Super Epic.

Common


Common Costumes are simple outfits for older Cookies, which provide very minor bonuses. Most Common Costumes do not change effects and merely change the Cookie's appearance, though Muscle Cookie's kettlebell is changed in his Curling Enthusiast costume, Werewolf Cookie has new sound effects in his Lonesome Shiba Inu costume, and Some Cookie's Ginger Claus Outfit creates gift sacks, which no longer have an effect.

Costumes from Halloween Party 2014 that were added to OvenBreak during Halloween 2017 are all Common, as are the Back to School Costume Set added on April 15th, 2018 and a few others. No Common costumes have released since the Back to School set. Common Costumes are purchasable at the Costume Shop for 50-580, and give one Rainbow Crystal when a duplicate is drawn at the Costume Gacha.

Rare
Rare Costumes are the most numerous rarity of Costume. As such, their cosmetic effects and gameplay bonuses vary. Holiday Wizard is merely a recolor of the default Wizard Cookie, while Angel Cookie's Jelly Walker and Rockstar Cookie's Flaming Guitar change visual effects and sounds. Other Costumes frequently change the visuals of skill effects as well. Some Costumes change the Cookie's liked and disliked gift in the Lobby, which is a gimmick that becomes even more common on higher tier Costumes. New Epic Cookies usually release with a Rare costume, which is included in microtransaction packages. Rare Costumes are purchasable at the Costume Shop for 660, 990, 1,280 or 1,480 depending on when they are released, and give two Rainbow Crystals when a duplicate is drawn.

Epic
Epic Costumes are typically fancy Costumes, Costumes that were limited before the Costume Gacha was added, or Costumes for old Cookies released after Knight Cookie's Icewind Cavalier on October 16th, 2019. Most Costumes of this rarity or higher change skill effects and the likes and dislikes of the Cookie in the Lobby. These Costumes are not purchasable at the Costume Shop, most being exclusive to the Gacha and purchasable for 30 Rainbow Crystals. There are exceptions, as three Epic Costumes are rewards from the Island of Memories, and Sea Overlord is exclusive to the Breakout Shop. Epic Costumes give four Rainbow Crystals when a duplicate is drawn.

Super Epic
The next level of Costume rarity contains very elaborate Costumes. Like Epic Costumes, they are only obtainable from the Gacha, at a much lower chance, or bought with 80 Rainbow Crystals. The exceptions are Lord of Ash, available from the Guild Shop, and Milky Way and Guardian of the Millennial Tree, available from the Medal Exchange Center. Dark Choco Cookie's Sovereign of Darkness is the only Costume for a non-Legendary Cookie that was reclassified as Super Epic, but Super Epic Costumes for other Epic and Rare Cookies have released since. Each Super Epic costume that can be drawn from the Gacha has a unique illustration when drawn, which can be viewed again from the Costume's description menu. Super Epic Costumes give eight Rainbow Crystals when a duplicate is drawn.

Legendary
The final level of Costume rarity was introduced in the Season 5 update. The sole Legendary Costume, Sea Fairy Cookie's Dread Trident of the Abyss, is similar to a Super Epic costume in design, but receiving it gives the Beyond the Abyss Lobby design, and equipping the Costume gives a matching Costume to Wave Drop, Sea Fairy Cookie's Pet. Like Super Epic Costumes, there is a unique illustration, but before it, a sentence is shown, and it changes the Cookie's gift preferences. The Legendary Costume has a mere 0.05% chance of being drawn from the standard draw, and if it is drawn a second time, it gives 15 Rainbow Crystals.
