Jimmy Firecracker is presented as an extremely biased and partisan interviewer, as at the start of the Cell Games, he staunchly believes that Mr. Satan is the strongest being on the planet, and downplays the Z Fighters as though they are nothing, particularly Goku, after he tries to warn Mr. Satan that he might get killed by Cell.
In spite of his flaws, however, Firecracker is also a rather brave man, shown when he is virtually the only man with enough courage to cover the Cell Games despite the danger of merely being present, and even attempts to interview Cell personally, backing off only when Cell refuses to speak to him. Though gullible like the rest of the majority of the Earth's populace, Firecracker appears to change his opinion about Mr. Satan and the Z Fighters after the tournament, since it took him a while to believe Mr. Satan when the latter claimed he beat Cell single-handedly.
At the start of the Cell Games, Jimmy Firecracker tries to interview Cell, but he refuses to answer his questions. He also constantly favors Mr. Satan at the Cell Games, and completely writes off the Z Fighters when they appear, even after Mr. Satan loses pathetically to Cell.
Later in the fight against Cell, when Gohan turns Super Saiyan 2, Firecracker finally realizes that Mr. Satan cannot be stronger than them. He appears to temporarily lose his mind near the conclusion of the Cell Games; not only does he continue to give commentary when they can not even see the fight or film it, but towards the end he starts talking into a stick as though it were his microphone.
Following the tournament's conclusion after Cell is destroyed by Gohan, Mr. Satan claims that he beat Cell single-handedly after Cell defeated the others (the Z Fighters simply left for Kami's Lookout). Though Mr. Satan's pupils easily believe the story, Firecracker, having seen Gohan's fight against Cell, demonstrates skepticism at first until Mr. Satan finally convinces him.
After the Cell Games, Firecracker and his cameraman Lionel are seen at Mr. Satan's victory parade. Lionel informs Firecracker that all of Cell's victims have returned to life, and Firecracker blindly hails Mr. Satan as the world's savior.
