Defender of New Earth
Jacobson started on his travels in search of a planet to protect and defend from any kind of threat. He saved some planets already but he just needed a main one to focus mostly on protecting. Finally, he found New Earth and was in New Britain which is different from the one on old Earth. This one has all versions of the old American English language and his Tardis took the disguise of a police booth with pale copper, pale yellow, and gray colors on it which is the colors of the law enforcement agencies on New Earth. Jacobson loves this planet and after staying there for a few years traveling it's history with him finding out after he traveled to another planet that his tardis is stuck in the disguise of a police booth from New Earth. He ended up loving it deciding that New Earth is the planet he will protect most from any kind of threats.
