Chaka is one of Marvel comics innumerable lesser-known supervillains and an enemy of Power Man and Iron Fist.
Thomas Arn was a teacher in a judo school. Several years after Robert Hao, the original Chaka Khan, was arrested, Arn took his place using Hao's costume and favorite weapon. He also rebuilt the street band of the Golden Tigers, probably choosing some of his best students as members.
The repeated crimes and extortions of the Golden Tigers forced the Lindon Street Company to send Power Man and Iron Fist to protect its businesses in the Chinatown area. The investigations and interferences from the Heroes for Hire caused a lot of trouble for the Golden Tigers.
Arn knew that the investigations of William Hao, Robert's brother, could be a problem for the Golden Tigers' activities and so he dispatched a squad of warriors to torture Hao before killing him. Arn wanted him to become an example for the people who stood against the Golden Tigers. When he saw that his gang members had to fight Iron Fist and Power Man too, Chaka intervened. His energized nunchaku knocked down Power Man, but the potential outcome of the battle was too uncertain, so he withdrew with his Golden Tigers and promised that there would be a reckoning.
Thomas Arn as Chaka However, the Golden Tigers' illegal activities kept getting spoiled by Power Man, who was following the gang as they committed crimes. Meanwhile, Daniel Rand enrolled in Ting So Ling school, as well as several other martial arts schools. While attending the training, he tried to guess who among teachers and students could be Chaka. Rand also visited Arn's school but he could not recognize anyone, but no-one recognized him either.
Later, a pack of Golden Tigers attacked Rand and Kevin Chang, and the fight escalated with the arrival of Power Man. Chaka then intervened to defeat his enemies. He managed to put Luke Cage out of the fight with his energized nunchaku, but, even using trickery, when he confronted Iron Fist in a man-to-man fight, he was easily defeated. Kevin Chang accused Arn to be a man without honor and witnessed against him. Arn was arrested and many victims of the Golden Tigers also attested to the gang's crimes.
