Clark Still is a member of the Ikari Warriors team and is great friends with Ralf and Leona. Before joining the Ikari Warriors, Clark worked as a spy that specialized in intelligence gathering, a skill that came in handy in his work with the Ikari mercenaries. Clark joined the Ikari Warriors and worked under Heidern and Ralf who are commander and colonel, respectively. Focused, professional, and steady, Clark is typically considered to be a much calmer individual than Ralf.
Clark was present for the King of Fighters tournaments 94 and 95 and was on hand to welcome Leona on board when she joined the team in 96. He was very helpful in stopping Leona when she experienced the ‘Riot of Blood’. He stopped Leona from taking her life and reminded her that she was no longer alone and now had a family. In the 2003 tournament, when the team lineup was increased to 4 fighters per team, Clark welcomed Whip on board, who was taken by his higher level of professionalism compared to Ralf.
Clark wears signature sunglasses, and it is said that they hide a scar on his forehead, which was caused by Ralf, who played with some blades a bit too freely.
Clark is a cool-headed character who focuses on compiling information for his team to get into action and perform their duties. Clark cares for his teammates and will always look to protect them from danger. Clark is not soft by any means, can do the job no matter how dangerous, and is sometimes considered emotionless. However, there is a hint of sadness about him that suggests some regrets of the past.
Clark is a grappler for all intents and purposes. However, unlike normal grapplers, Clark has a different aim in a fight and will like to get you knocked down before throwing you into the blender which he does very effectively. Clark is also not dependent on meter and can work well without it making him a flexible character. Clark is not without his faults, as he can find it hard to get in against zoners and doesn’t have the best anti-airs.
