Heidern (ハイデルン) is a character in The King of Fighters series who debuted as a playable character in The King of Fighters '94 in the Brazil Team (later known as the Ikari Team), along with Ralf Jones and Clark Still.

Heidern is the commander of the Ikari Warriors, and issues orders to his adopted daughter Leona and his best soldiers: Clark Still, Whip, and Ralf Jones. His official nickname is General of the Soldiers of Fortune. (フォーチュンソルジャーズジェネラル).


He was conceptualized to be a "cold-blooded killing machine", but his designer grew attached to Heidern and gave him a tragic past.[2][3] His namesake is a character from the anime, Space Battleship Yamato. His eccentric and uncommon fighting style surprised some of the staff, and they humorously wondered if they should add a supernatural quality in his character history. Toyohisa Tanabe states that Heidern was added to be the "particularly strong" character at the time of his debut.

In regards to his tragic past, the developer asked the planner what Rugal thinks of Heidern, as Heidern clearly despises him; he responded: "Well, Heidern basically was just in the wrong place at the wrong time when he crossed paths with Rugal... and Rugal just swatted him like a fly, kicked him aside like a rock in the road." [2]


Very calm and silent, Heidern's personality was built because of the trauma of losing his eye and his family to Rugal. Although he hides his emotions through a veil of professionalism, he cares deeply for all of his subordinates, especially for Leona. Heidern is very strategic, especially when trying to stop a major threat, and has used his group Ikari Warriors to deal with such threats appropriately; he has been known to enlist mercenaries and free agents too.

Outside his sphere of acquaintances, he can be either confrontational, haughty or demanding on the skills of whom he comes up with, and doesn't mince words to call out what he perceives as inferiority. He's quick to praise competence and effort in fighting, however. Whenever he faces anyone he has encountered before (ie. acquaintances, allies, employees, subordinates or colleagues) in combat, he is rather respectful and recognizes their will to be strong.

Heidern is not above accepting help from others, even accepting the help and intel contribution of Adelheid Bernstein, the son of his enemy, the late Rugal Bernstein.


  • Slashing Hands - Heidern's hands can cut and pierce as if they were knives.
  • Cutting Aura - Aside of his slashing hands power, Heidern can create a cutting aura around his arms.
  • Cutting Projectile - Heidern can send a cutting/piercing projectile flying with his hands.
  • Absorb Life - By piercing his hands in his enemy's body, Heidern can absorb his or her life-energy and refill his own.
  • Explosions: Heidern can create explosions, through his own gloves. His adopted daughter also learns this ability from him as well.

  • Tactical Administration and Management - Being a leader of a military-like mercenary group, he has managed and dealt with several personalities, including his own band of soldiers, the Ikari Warriors. Apart from Ralf, Clark and Whip, he hires mercenaries and free agents to expedite work, as he is seen assigning missions to Vanessa, Seth, Ramon, Blue Mary, and many others as well.
  • Tactical Planning - Seen in KOF '99, KOF 2000 and KOF XIII, Heidern has been the brains behind coordinated actions against many of the series' organized antagonists, with significant results.

Fighting style

Heidern employs his self-made fighting style. Said fighting style is a striking martial art with emphasis on his cutting hand strikes. He is the master of his own brutal self-made martial art, involving cutting with the use of bladed gloves, which seem to conceal explosives and a form of energy generator (used for his signature attack, Storm Bringer, which is a reference to the famous Stormbringer sword).

In KOF 2001, he has been turned into a circle motion-based character instead of his usual charge-based moves. This was corrected in his appearance in KOF 2002 UM, where he reverts to his charge-based commands.

  • Heidern has also used the codename "Bechstein" in the past. Adelheid also gives him the nickname Heidi, which is a reference to the German novel character.
  • In the Ikari Team's backstory for XI, Ralf mentions that his and Clarks relation with Heidern is best represented by the white magnolia flower from the funeral they attended. In flower language, it means deep unspoken trust.[4]
  • In KOF '94, Heidern had a bug where he could increase the damage of his next Storm Bringer or Final Bringer attack whenever he whiffs his Moon Slasher, often leading to a one-hit-kill. In later games however, it functions as a slight easter egg that has been re-balanced to prevent it from being game-breaking, as the damage increase is no longer as apparent and is quite slight-yet-still notable (and also applies to his later Killing Bringer move as well).
  • In the Game Boy version of KOF '95, his name is misspelt as 'Jeidern'. However, in the Japanese version, his name is spelt correctly.
