Chronological information
First appearance Chapter 9
Status Dead, in possession of Tom as a corpse

Most of the Warner Bros shorts where Tom and Jerry chase each other around appear to have still happened before the comic. While Tom can talk and interacts with human characters, Jerry appears to be the same as he always has been, remaining mute. Tom eventually baits Jerry in with the promise of amazing milk, prompting Jerry to come drink some of it. The milk is poisoned and kills Jerry. Tom has actually tried this before in real Warner Bros. shorts, but the result caused Jerry to randomly gain superpowers instead of killing him. Tom attempts to devour Jerry, but discovers his newfound necromantic powers and animates his corpse, playing around with it to gain experience with his abilities.

Jerry is eventually seen again attacking the troll base under Tom's command, alongside other corpses Tom has acquired such as Spike and Granny.
