Major Story Arcs

Meeting Gwenpool

Jeff was living in a secret lair of the supervillain who created the Land-Sharks. During an assault by the West Coast Avengers on the compound, Gwenpool found the baby land shark and immediately took a liking to him. She named him Jeff the Baby Land Shark and introduced him to her other teammates from the West Coast Avengers. At first, the other heroes where sceptical of Jeff, but they soon embraced him. Jeff became friends with Clint Barton (Hawkeye)'s dog, Lucky the Pizza Dog.

Brought to Deadpool

With Gwenpool's real-life comic being cancelled (and with Gwenpool breaking the fourth wall in comics and therefore actually knowing her comic got cancelled), she took Jeff towards Deadpool and asked him to take care of him. She wanted to make sure that Jeff remained in an ongoing comic. Since then, Jeff and Deadpool are the best of friends, with Jeff helping his new boss out on a number of times.
