We all have our childhood favorites. From food to toys to games, there are some things that give us an absolute sense of nostalgia. And for a big chunk of us, Garfield definitely belongs in the ranks.

For some, it was a comic to read and enjoy, for others, it was a cartoon to glue our eyes to, and for later generations, it was a flashy game online. But we’re all familiar with the lazy, fat and cynical orange cat who loves lasagna and hates Mondays. And although Garfield brings out good memories full of laughter and nostalgia, the vast Garfield universe that spans over 40 years has some rather chilling aspects to it.

One Tumblr user made an outrageous claim that Garfield’s owner Jon murdered Odie’s former owner Lyman

A Tumblr user with the fitting name “jon-arbuckle-murdered-lyman” shared their take by announcing that, well, “Jon Arbuckle murdered Lyman in cold blood as a means to obtain Odie for his own cruel purposes”. While at first glance this claim seems outrageous, other users were quick to point out that it might have some weight to it.

Turns out, there’s more to the claim than just a speculation as Garfield’s lore is full of creepy details

Lyman was one of the main 4 characters of the original comic strip. He was the owner of Odie and roommate of Jon Arbuckle, and the 4 lived under one roof where most of the stories took place. However, Jim Davis, the creator of the comic strip, decided to remove Lyman and reduce the main line-up to only Garfield, Jon, and Odie.

For years, Lyman remained absent from the series with the writers constantly changing Odie’s origins to the point where Lyman was removed from the story altogether. He became a sort of ghost that some readers remembered but couldn’t explain why or where he disappeared.

Perhaps that was the reason why Jim Davis eventually gave out a list of possible explanations of where Lyman has gone. Most of the list was full of comical scenarios like Lyman joining the Peace Corps and never being heard from again, however, the final reason had some fans concerned. “Don’t look in Jon’s basement” was the final entry on the list and considering the comic’s tone, could’ve been taken as a joke or an actual possibility.

While in the writing world, the removal of Lyman from the story made sense (as his original role of being someone whom Jon could talk to was gradually transferred to Garfield), the in-universe reason remained a great mystery for a long while, prompting fans to come up with some chilling theories.
