Harmon was friends with famous viking Leif Erikson up until Leif died in 1020 AD. Harmon himself wasn't a viking, but his old age made him wise, and thus him and one of the most famous vikings ever, Leif Erikson, became good friends through wisdom and leadership. Harmon was always much older than any of his friends, usually by magnitudes of billions of years, but he has seen much of the planet's development. Leif tragically died in 1020, and Harmon was torn about this occurrence.

Harmon's dinosaur friend was Blarg the Dinosaur. It was a Stegosaurus living about 161 million years ago. Harmon was good friends with this dinosaur, despite the language difference. They managed to bridge this gap and become best friends until a world shaking meteor crashed down instantly killing Blarg. Harmon, however, is immortal and the meteor left him unaffected. Many believe Blarg actually died many millennia before the meteor and that Harmon couldn't let him go, but that story is not yet confirmed.

A few thousand years later, Harmon would meet Grunka the caveman, and forget about Jimmy entirely.
