Gizmo has seen limited interaction with TMNT characters. A two-issue mini-series was produced in 1989 called Gizmo and the Fugitoid, which was written by Dooney and Peter Laird. Fugitoid himself was a crossover element to the TMNT with from his own story in Gobbledygook. The Gizmo and the Fugitoid story takes place following Fugitoid's story arc in Eastman and Laird's Teenage Mutant Ninja Turtles volume 1. Gizmo was later seen in as a cameo in the audience, along with Fluffy, of a Stump Wrestling match during Teenage Mutant Ninja Turtles Adventures.
