Some TMNT stuff really isn't for little kids.

Baxter is a dog appearing in Donatello: The Brain Thief #4. After Baxter Stockman's robot body was destroyed his right arm came alive and started to replicate organic lifeforms as it was looking to assimilate Baxter's brain. After the robot ate a homeless man. Don takes the opportunity to go grab his “secret weapon”: the dog that belonged to the homeless man the robot ate. By pure luck, the dog happens to be named “Baxter”. Don asks the dog to sit and speak at the sound of his name, proving to the robot that the dog is indeed Baxter. Content to fulfill his objective of assimilating Baxter’s brain (any Baxter's brain, really), the robot kills the dog and takes its form.

The robot dog is now mindlessly obedient to Don and follows him down a winding path to an ancient and forgotten area of the sewer, where Don has a high-tech vault. Don directs the robot dog into the empty vault and tells him to sit and stay. Don then shuts and locks the door behind him, destroying the key remote and calls it a day.
