What kind of stuff do you think Delta would do on his birthday, or what would the Epic Sanses do for him? I have an idea
I like to think a big part of it is competing in the Omega Timeline’s Coliseum. I like to think he and Cross actually spend a lot of time leading up to his birthday training to compete—going to the gym, running a mile or two every two to three weeks for a an entire week, maybe going to specifically created gyms or areas where it’d be safe to train with powers and magic as well as weapons.
Intermixed with training with Color specifically on how to use the bravery soul, since im pretty sure superyoumna mentioned that is actually a thing that happens.
I also like to think he and Epic team up to torment (prank) killer for all his assholish ways leading up to dee’s birthday, create their personal karma. I doubt they do this every birthday, simply because one killer would grow to expect it eventually and two it’s supposed to be a fun day and tormenting killer everytime (especially if he hasn’t actually done much shit leading up to it) would eventually just be mean and not funny or fun at some point.
I also like to think he also takes beta and zorox to visit some type of graveyard for the people from their au—frisk, papyrus. Either one the omega timeline has set up, or somewhere self made, personal and private.
