Peter is not a punishment or a curse on him, as Walter had believed. "Michael" / Anomaly XB-6783746 "Michael" is a child Observer (portrayed by Spencer List and later by Rowan Longworth), first introduced in the first-season episode "Inner Child" and later re-introduced in the fifth season. The name "Michael" is given to him by adoptive parents who protect him in the 2036 future, as shown in the episode "Black Blotter", while later Captain Windmark cites him as Anomaly XB-6783746 in the episode of the same name. Michael, like other Observers, is pale and bald; however, he does not possess the implant used by other Observers to further boost their intelligence while suppressing their emotions (and allowing them to time-shift). He is mute, but is able to communicate via writing, symbolic gestures, or by touching others and implanting thoughts into them.

In 2036, Fringe is able to track Michael down, after discovering that he's missing from the pocket universe. Michael is revealed to be September's progeny, created from September's genetic material sometime in the early 27th century. September purposely stopped the growth process, leaving Michael a child possessing both a powerful Observer-intellects and human emotion, creating an anomaly in danger of being destroyed by the Observers. September takes Michael to the past to hide him from the Observers. Much of September's machinations with Fringe in the first four seasons were to prepare Walter to use Michael for their plan to defeat the unemotional Observers ("The Boy Must Live"). In 2036, September, who has been made human by the
