Today's Fact
Everyone calls him a baby shark. The comics quietly insist he is finished growing, and the evidence comes from thirty years in his own future.
Call him Jeff the Baby Land Shark and you are only half right. In Deadpool Vol. 8 #3 (2020), the entry for Jeff in Deadpool's own monster guide can only manage a guess, describing him as a tiny land shark with the word baby followed by three question marks.
Writer Kelly Thompson settled the question in her other book. Captain Marvel #22 (2020) returns to the scorched future of 2051 first built in Captain Marvel: The End, and waiting there is an elderly, grizzled Jeff — scarred, seasoned, and still small enough for Carol Danvers to scoop up and carry in her arms.
Thompson later spelled it out plainly: the Jeff of Earth-616 is young, but he is simply the runt of M.O.D.O.K.'s batch. His giant siblings got the size. He got the proportions he will keep for life, roughly two feet of shark, finished and complete.
