Proton weapons

The proton weapons were variants of the Ninja Turtles' signature weapons based on the Ghostbusters' technology, which were featured in Teenage Mutant Ninja Turtles/Ghostbusters 2. Using weapons purchased by Janine Melnitz, Donatello crafted an arsenal of proton-based ninja weapons that could be used to damage the Collectors.

The Turtles used their proton weapons in the final battle against the Collectors, which hurt the Collectors but did not fully defeat them. After the demons were drawn through the trap-gate, the proton weapons burned out.
