Powers and Abilities

Heidern’s hands can cut and pierce as if they were knives. Aside of his slashing hands power, Heidern can create a cutting aura around his arms and can send a cutting/piercing projectile flying with his hands.

Lastly by thrusting his hands in his enemy’s body, Heidern can absorb his life force and fuel his own.

He’s also a highly skilled and disciplined soldier and field commander of international renown and has all the skills to go along with that.


Ikari Warriors

Ralf and Clark summoned to the remote jungle village of Ikari to assist Commander Heidern in putting down a dangerous guerilla rebel force. While the exact country is not name it is most likely Brazil as they would later wound up being based there.

(Note that Commander Heidern was originally named General Kawasaki in his first appearance. The game director Eikichi Kawasaki just couldn’t resist putting himself in the game. He has since been retconned  into being Commander Heidern.)


Their intel proved to be outdated though. The rebel faction had already taken both the village and Heidern. En route to their meeting their plane was shot down. After crawling out of the wreckage they elected to shoot their way through an army to reach their objective.

They were able to liberate the village and free Heidern. The Commander in turn thanked them for their service and arranged for a military plane to fly them back to America.

Ikari III: The Rescue

Ralf and Clark were ordered by Heidern to rescue a young girl who had been kidnapped by the Crime Ghost. The girl was actually the daughter of either the president or a presidential candidate. (Sources vary and the official game release doesn’t really make it clear which was correct.)

They were able to fight their way through his army of thugs and rescue the girl.

Rugal Bernstein

Due to his exceptional track record Heidern was further promoted. He was also given his own secret base with a support staff. However the international criminal known as Rugal Bernstein had caught wind of this. In order to discourage other agencies from going after his ever growing criminal empire, Bernstein decided to make an example of Heidern.

He stormed the award commencement ceremony. Bernstein is said to have killed some 50 men as well Heidern’s wife and daughter right in front of him. Heidern furiously fought him, but he was severely outmatched.

Typically Rugal would kill his foes and then making them into statues aboard his flying airship the Black Noah. However, he deemed Heidern unworthy. Therefore, he plucked out one of his eyes before leaving him amongst the carnage.

Heidern then founded a new version of the Ikari Warriors to deal with this new threat.

A new force and another daughter

The Ikari Warriors Mercenary Group is an ultra-elite paramilitary organization. But despite being called mercenaries there is no evidence of them fighting for money. In fact they behave more like superheroes that have swapped out their spandex for military fatigues.

These Ikari Warriors go after the worst international criminal organizations. They could easily be a classified branch of Interpol or another international law enforcement organization. Their mercenary aspect and Ralf and Clark being likely disavowed by the US military could easily be part of a cover to keep them as a sort of deniable asset.

While out wandering in the jungle, Heidern came across a young girl. She was scared out of her wits and covered in blood. Upon further investigation he found a nearby village that had been massacred. The girl was the sole survivor. She reminded him of his dead daughter Clara.

Heidern adopted little Leona, hoping both that she could fill the void in his heart and that she could live a better life. It goes without saying that he began training Leona in all manner of military combat from a young age as well.

King of Fighters ’94-95

Looking for vengeance, Heidern ordered Ralf and Clark to accompany him to the King of Fighters tournaments that Rugal was hosting. The plan was to make it to the finals to get a shot at him. The Ikari Warriors are presented as one of the more prominent teams, so them making it to the semi-finals or some such seems likely.

But regardless they washed out of the tournament. It was Kyo Kusanagi and his Japanese team went on to defeat Rugal.

Rugal seemingly perished during the events of the first tournament after his ship went down. However, he reappeared alive and well the next year to host another tournament. Albeit he was now fitted with cybernet enhancements as super villains tend to do.

Bernstein was finally killed for good at the culmination of the ’95 tournament.

King of Fighters ’96

With Rugal dead Heidern felt a sense of closure and went into semi-retirement. He was still actively involved and the leader of the Ikari Warriors. But he mostly remained at the secret base to quarterback operations assigned to his younger operatives.

The Ikari Warriors were assigned to participate in the ’96 tournament. The mission was to keep an eye on the recently returned kingpin Geese Howard. Heidern stepped aside and appointed his daughter Leona to take his place in the tournament.

King of Fighters ’97

(Heidern was aware of the following events, but did not take an active role in the field for most of the rest of the series.)

The Ikari Warriors team did well in this tournament and were in the finals. But they had to drop out as during the climax Leona entered the Orochi Riot of the Blood.

Unbeknownst to them, the Orochi, an ancient race of demons hell bent on the destruction of the human race, had been manipulating events behind the scenes at first to gauge and later to wipe out the strongest fighters. The Orochi made themselves known during the climax. Leona lost control as she was actually a descendant of their clan.

The duo were able to subdue her. Over the following year, they helped her come to terms with her dark heritage. While Clark was actually able to get time off to help her deal with this, Ralf wasn’t due to his higher rank. He later feigned incompetence during a mission in order to get suspended. That allowed him to spend time with Leona.

King of Fighters ’99

The next tournament changed the rules from three man teams to four man teams. Their fighter was a mysterious new recruit named Whip. Although she didn’t speak much the team eventually bonded and they grew to consider her a comrade in arms.

King of Fighters 2000

Whip eventually went missing during the tournament under mysterious circumstances and the team frantically searched for her.

King of Fighters 2001

Whip later resurfaced as part of K’s team along with Maxima and Kula Diamond. The Ikari Warriors had a brief confrontation with them, but K’s team managed to elude them.

King of Fighters 2003

Whip was later reinstated and rejoined the team sometime in 2002.

The Ikari Warriors were tasked with locating with locating the Sky Noah. This mysterious ship said to be connected to one of their former nemeses. Due to the Orochi seal being broken again, their mission went awry when Leona once again entered Riot of the Blood. Ralf and Clark once again were forced to subdue her.

King of Fighters IX

Shortly before this tournament of Ralf and Clark were attending a funeral for their fallen comrade Jim Aldgate. After the funeral Heidern voiced concern of the revival of the Hakkeshu and the breaking of the Orochi seal.

The Ikari Warriors have participated in all of the tournaments after that. However, they have not had a major impact on the main storyline. They were able to retrieve the main villain Magaki’s corpse after the dust had settled, but it was taken from them by two members of Those From the Past before they could send it back to their lab before tests.

Though they likely had a hand in it those plot lines were mostly resolved by other characters.


Heidern wears a military uniform with a somewhat sinister vibe. He has a patch over his right eye and speaks with a deep gravelly voice that can often be heard barking orders. He also has a fearsome presence that demands respect and loyalty befitting of a military commander.


“You can’t avoid the bite of my steel. Scary, huh ?”

“You can’t win against real style like us, bozo !”

“You say you let your guard down ? I think you’re just a weenie !”

“I’ll say one thing: I am invincible.”

“KOF always has great guys, but they’re just brawlers.”

“You were like a shooting star. Your ambition was the cause of your destruction.”

“Don’t you get it ? Lost concentration is death.”

Previous statistics

During ’95 and ’96 when Heidern was squaring off with Rugal Bernstein he had a number of Drawbacks:
Enemy (Rugal Bernstein, powerful), Guilt (death of his wife and daughter), SIH (Rugal Bernstein) and reduce HPs to 40.

After Rugal was finally killed once and for all when the Orochi power consumed him Heidern has managed to put all this behind him. He has settled into a comfortable semi-retirement and mostly operates as the field commander and trains news recruits. Leona, his new adoptive daughter, also helps fill the void of his lost loved ones.
