I dunno, Undertale took place some indeterminedly long time ago that Gerson was in his prime and Chara was stated to live in a village, but monsters don't have defined lifespans outside of Boss Monsters being immortal unless they have children (Asriel's death locked Toriel and Asgore's ages forever, Gerson also says this) so Toriel and Asgore can't be used as a yardstick, Asriel was born recently enough that Toriel was recording things on VHS when she was pregnant with him, and Chara wandered in wearing modern trousers and shirts. Considering Rudy's own status as only canonical to Undertale because of an alarm clock app's dialogue that never got finished it's weird where he's supposed to fit in there. The only thing really known for sure is Dess is alive in Undertale's continuity, their friendship was recent enough that his daughters are still alive, and Asgore knew Rudy when Rudy was very young all the way up until his death of natural causes

tl;dr I am thinking about Undertale vs. Deltarune's chronology and Rudy's place in the world harder than Tobert is
