Jameson is editor-in-chief of the Daily Bugle, a New York newspaper. Jameson was raised by his stepfather, his biological father's brother. This is who he learned to love cigars from. His biological father J. Jonah Jameson Sr. left the country for unknown reasons. He was a Boy Scout during his childhood. In high school, his interests were mainly boxing and photography. He met his first wife, Joan, when they both joined their high school's photo club. When the school's three top athletes started bullying him, he fought back and beat all three of them to a pulp. This impressed Joan, and they started dating. They married as soon as they finished school. After school, Jameson sought employment as a journalist. When the U.S.A. joined World War II in 1941, Jameson served as a war correspondent in Europe. Jameson gained a mostly deserved reputation for journalistic integrity, but his greedy opportunism and unyielding belligerent stubbornness made him more than a few enemies. Jameson has also been a tireless crusader for civil rights. He has also agitated in print on behalf of labor union rights. He has even stood up for mutant rights, despite his dislike of superhuman individuals. "Who is Spider-Man? He's a criminal that's who he is! A vigilante! A public menace! What's he doing on MY front page?" Jameson is an accomplished reporter, editor and businessman, knowledgeable in virtually every aspect of print publication. He demonstrates surprising fitness, though he is subject to fits of rage, has had multiple heart attacks, and is a chain smoker of cigars. His brusque behavior, capitalistic outlook and obsession with Spider-Man frequently mislead people into believing him less principled and compassionate than he in fact is. Recognizable by his mustache, flattop haircut and ever-present cigar.

This Disadvantage is similar to both Overconfident and Arrogant, but has important differences to both. A character with this Disadvantage becomes so proud of their recent successes that they believe that they not only will win, but also not get hurt by the outcome of most events, and thus aren't overly worried even when they should be. This character will not be Overconfident in all situations—just those in which he recently had some measure of success (for example, if during a fight between the character's team and a villain team, disabling one opponent will cause the character's Cockiness to spring to the fore, even though during the strategy session before the fight the character admitted that the combat would be tough going). This character has something in his life to which he is dedicated. The specific goal is up to the player, but it should be some appropriately dramatic goal. For example, Committed to Destroying Viper or Committed to Rebuilding Saint Michael's Cathedral After Its Destruction by Mechanon are appropriate goals. Committed to Collecting All the Episodes of M.A.S.H. isn't. The Frequency (Uncommon, Common, or Very Common) of this Disadvantage depends on how often the character encounters opportunities to pursue it, as determined by the GM. A character with this Disadvantage simply cannot say no to a game of chance. As long as there is the slightest chance that the character will win, he will make a bet. The actual form of gambling does not matter; slot machine, sports bet, poker game, or even the lottery all call to the character. In order to avoid joining the game, the character must make a successful Ego Roll. A character with this Disadvantage is sarcacastic on a whim, having a cutting remark for every situation, regardless of what the situation is. His remarks are not intentionally cruel, but they are always stinging. The level of wit involved in the characters sarcasm is up to the player, but the wittier the better. At the Moderate level, the character can control his urge to be sarcastic when necessary. At Strong, he can only do so if he makes a successful Ego Roll. This Disadvantage works well with Cynical, Loner, and Pessimist.
