Whip (nicknamed as Muchiko) is the newest member of the Ikari Warriors Team. She marks the official debut in the Metal Slug series in Metal Slug Defense.
Just like Ralf and Clark, her past is best to remain a mystery. Rumors about her past include working as an assasin for an unespecified corporation, deserting, and changing her name to enter the Regular Army. She is eventually assigned to Heidern's mercenary unit under her current name, Whip. When she was new, Ralf used to call her Muchiko (Japanese for "Whip Girl" or "Whippy"), a nickname that she claimed she didn't like. She is also known to enter fighting tournaments alongside the rest of her team, destroying the corporation she used to work for in the course of those. She is a calm and pure-hearted girl that is very confident about herself. She has found hopes for a better future and being happy once again with her squadmates Ralf, Clark and Leona.
Metal Slug Attack
She was sent by Heidern in order stop The Union that had gone on a rampage on the city. This mission also gave her the chance to test her newly modified whip that has the special ability to deflect Energy Projectiles and the New Golden Revolver.
- Whip originally appeared in the King of Fighters fighting series. With the exception of The King of Fighters 2001 - 2003 (where she is part of K's team) and The King of Fighters XII (which is not team based), in every appearance she is part of Ralf and Clark's team.
- Her favorite food is honey.
- In Metal Slug Defense, Version 1.44, Whip, along with Heidern, appears now as playable units as opposed to character art in game. Both units cost 300 Medals each.
- She also appears in Metal Slug Attack, initially as a pre-purchasable unit (ver. 1.15.0) and currently obtainable by Medal/V.I.P. Crank (ver. 1.17.0).
