Star vs The Forces of Evil x Male Asriel Dreemurr Reader:

In this version of Star the Monsters from the Underground will be running their own kingdom.

You're friends with Star and as the series goes on you'll gain access to your God form.

At one point you'll even become Flowey and turn into Omega Flowey for a good duration and be an antagonist of your own arc.

Also since you didn't die yet, Asgore and Toriel aren't split up...yet.

As I said...you do become Flowey at one point and we all know how that affected the goat couple.

Can't wait to write a battle between these 2.
