Chloe is a new character introduced in Metal Slug Attack.
A one-of-a-kind woman, she's also a high-strung perfectionist, refusing to make any compromises and often argues with the mechanics who oversee Naglfar. In addition to this, she respects Rapid, the head of the transportation unit, wishing to become friends with her.
Chloe makes her very first appearance in the cutscene of the Extra Ops titled "Christmas Wishes", where she is assigned guard duty at a remote area considered to be Rebel territory with a Hodumi++. Teleko arrives to take some of the trees for Odette. Chloe attacks the Invader, though she finds herself outmatched by the Invader's telekinetic powers and swears revenge on her. Since her machine and communication device were destroyed, she ends up walking through a blizzard; while walking, she encounters a silver-haired child in the distance.
- Despite first debuting as a unit in the "United Front the 1st" Extra Ops, Chloe did not have any speaking role or mention from other characters until the "Christmas Wishes" Extra Ops, a little over one year later.
