Jesse is my new O.C for Undertale. No, he’s not one of the six human souls. He and his dog Rover came after Frisk free the monsters from the Underground. He’s been adopted by Asgore and Toriel so yes, that makes him a brother to Frisk.
I hope you like it and this is an app game I did on my tablet. So I won’t be able to give the link cause it’s an app but I can give you the name of the game if you’re interested in playing it. Just ask me about it and I’ll give it to you.
