Edison (named Newton in the UK version) is a male firefly character who first appeared in JumpStart 2nd Grade. He is CJ's best friend and partner.

In the past, he and CJ were often the mascot characters for JumpStart's 2nd Grade media.

Despite being a prominent character for many years, he has not appeared in any recent media. His last notable appearances were in the JumpStart Advanced series.


In JumpStart 2nd Grade, Edison was depicted with tan skin, gray eyes, long skinny tan antenna, and a bright yellow lower abdomen. He wore a green bowler cap with a light yellow band around it, a green shirt with a red bow tie, white gloves and black shoes. A prototype design of Edison for this game depicted him with red shoes, a green bowler cap with a red band, a more whitish lower abdomen. His prototype design also lacked a shirt, bow tie, visible eyebrows, and irises.

In JumpStart Math for Second Graders, Edison had bright blue antenna and a bright blue lower abdomen. He wore a green vest, an olive green tunic and shoes, and a tall red and purple striped hat. In JumpStart Reading for Second Graders, his design was strongly based on his original appearance, with the main difference being that he lacked a bow tie.

In JumpStart Around the World, JumpStart Preschool: Who Left the Juice in the Caboose?, JumpStart Kindergarten: Why Did the Bus Stop?, and JumpStart Learning Games: Phonics, Edison has green skin and a red nose, and he wears an orange cap and a blue sweater. Starting with this design, he ceased to have visible antenna.

In the JumpStart Advanced series, he is depicted with light blue-green skin and a red nose, and he typically wears a purple cap and a blue t-shirt.

Personality and Characteristics

Edison is usually depicted as being pragmatic and having a somewhat dry sense of humor, particularly in his debut in JumpStart 2nd Grade. He has always been depicted as having an Irish accent and sometimes using Irish idioms.

In JumpStart Reading for Second Graders, Edison seems more drawn to treasure and the rewards of an adventure, in contrast to CJ who seems more excited by the adventure itself. At one point Edison mentions, "Rubies and diamonds? Now they're talking my language!" Edison is also more cautious than CJ in this game, and more prone to being suspicious of strangers, in contrast to CJ who is more openly trusting.

Edison has sometimes been shown to be cowardly and less enthusiastic about going on adventures than CJ, such as in JumpStart Advanced 2nd Grade: Fundamentals and JumpStart Artist, but still always goes with him, presumably due to their friendship.

In the Advanced series, Edison is depicted as being much more optimistic and adventurous than his previous incarnations. In the video JumpStart Jukebox, Edison states that he loves to go on adventures, just as CJ does. He also mentions that his favorite subject is science, and he has a keen interest in nature as well.

In JumpStart Advanced 2nd Grade: Mystery Club Vol. 1, it is mentioned by others that Edison likes wooden things and seashells, and that he enjoys combing the beach for things that wash up on shore.
