Time Scepter

The Time Scepter is an object that shows up in several TMNT continuities. It is normally associated with Lord Simultaneous and Renet.

Movie III
Unlike the other incarnations of the item, the Scepter is not said to be related with Simultaneous, Renet, or any other associated characters. Instead, it is bought by April as a gift to Splinter. In feudal Japan, Kenshin also holds the scepter, causing him to switch places with April, landing him in the present, while she travels to Japan.

Video Games
In Teenage Mutant Ninja Turtles 3: Mutant Nightmare, Ultimate Drako steals Simultaneous' Time Scepter and uses it to warp the Turtles across different alternate dimensions.

The Time Scepter makes a re-appearance in the packed-in comic book for Teenage Mutant Ninja Turtles Smash-Up, where Donatello uses it in an attempt to instantaneously transport the Turtles, Splinter, April, and Casey to The Shredder's Japanese headquarters. The Scepter malfunctions, and the group ends up hopping to an Amazon rainforest and feudal Japan before finally arriving at their destination.
