Pet in an in-game RPG
Rabu
Last checked 2026-11-03
Rabu is not a boss in the apartment building. Rabu is a pet in Massacre Princess Catholicon, the video game Sam can play. Torment Beam is the skill people are asking about. The Final True Ending’s slides are where that beam becomes a story object.

Why this page sits under bosses
The search volume is real, and the category is wrong. I am keeping the URL players will guess, and the first sentence contradicts the folder. If you came for a weakness chart, there isn’t one, because there isn’t an apartment fight with this name on the boss list I used.
The sheet that does exist is inside the fictional RPG: 378 HP and 15 attack on the wiki’s pet row. No level is printed. Those numbers are Catholicon numbers. They are not comparable to the Furnace’s 1600 or to Baby Teeth’s 320, and I will not put them on a shared “boss HP” ranking.
Final True Ending is the route that cares. The endings page’s conditions include choosing violence enough times, buying and finishing Massacre Princess, using Meteor Strike, and then a damage check on the Visitor. Rabu’s beam is part of why the in-game RPG is on that checklist. I am not retelling the slide show. I am telling you the pet is a requirement’s mascot, not a roof encounter you can target with a wrench.
Sam learns Meteor Strike from the apartment’s games, which is a different cartridge from Catholicon. Both games matter for that ending. Mixing the cartridges is how a pet hunt replaces a skill hunt. Meteor Strike is Sam’s. Torment Beam is Rabu’s.
There is no recruit into Sam’s party. Playing Catholicon puts Rabu in that game’s party. Spine, the Spider, and Joel are the apartment recruits people confuse with “a weird companion.” Rabu does not walk the halls.
