Initially perceived as hostile for being a Kraang, Bishop explains his background as an Utrom, and how the Utroms are a peaceful group of Kraang who defected and how they oppose the Kraang Hive Mind. Bishop, who uses a Norman suit, explains that he was the original designer of the Normans. He also reveals that Kraang Subprime was himself once an Utrom, but defected to the Kraang. Bishop wins over the Turtles' trust and helps them fight against the simultaneous invasions of both the Kraang and Triceratons.
It was later revealed that Bishop had escaped from the Triceraton attack on the Technodrome by riding Leatherhead to shore. He rejoined the Turtles to help them disable the Heart of Darkness. However, the Triceratons destroyed Bishop's suit and he scuttled off.
Bishop encounters the Turtles again, but this time, in Dimension X.
Bishop is a helpful and caring Utrom. He made a Utrom vow not to deal with Earthly matters but broke it to warn the turtles about the Triceratons.
