According to this fictional biography, he was born in Leland, Mississippi, alongside approximately 2,353 siblings. As portrayed in the 2002 film Kermit's Swamp Years, at the age of 12, he was the first of his siblings to leave the swamp, and one of the first frogs to talk to humans. He is shown in the film encountering a 12-year-old Jim Henson for the first time. According to The Muppet Movie, Kermit returned to the swamp, where a passing agent noted he had talent and, thus inspired, he headed to Hollywood, encountering the rest of the Muppets along the way. Together, they were given a standard "rich and famous" contract by Lew Lord of Wide World Studios and began their showbiz careers. In Before You Leap, Kermit again references encountering Jim Henson sometime after the events depicted in the course of The Muppet Movie and details their friendship and their partnership in the entertainment industry, crediting Henson as being the individual to whom he owes his fame. At some point after the events of The Muppet Movie, Kermit and the other Muppets begin The Muppet Show, and the characters remain together as a group, before starring in the other Muppet films and Muppets Tonight, with Kermit usually at the core of the stories as the lead protagonist. Kermit is shown in The Muppet Movie as stating that the events of the film are "approximately how it happened" when asked by his nephew Robin about how the Muppets got started.

Sometimes it does get too much and he becomes frustrated but essentially he kind of goes with the flow and is always able to calm back down and find a solution to the problem. Kermit is the type of leader the world needs.
