T-Phones are phones that the Turtles use in TMNT. The T-Phones are designed for the Turtles to communicate with each other, and coordinate their movements in the area. They were made by Donatello. Donnie even implanted a Self Destruct mechanism in the phone, so that if it should end up in the wrong hands, the user could simply say "T-Phone, Self Destruct!", and it will explode. All the Turtles carry one, including April and Casey. The Ring-tone is a chip tune version of the theme song from the 1987 TMNT cartoon. The Tphones have proven to be very powerful, as Donnie is shown to be able to use them to hack into advanced alien technology. In a word, the T-phone is the Swiss Army Knife of all cell phones. They made their debut in Monkey Brains.
- "T-Phone" is a parody of Apple Inc.'s "IPhone".
