(I like undertale and now getting into Deltarune fandom, i felt like doing this.)

Edd- Frisk/Toriel
Tom- Sans/Undyne
Matt- Papyrus/Mettaton
Tord- Flowey/Chara
Eduardo- Mad Dummy
Jon- Temmie/Monster kid
Mark- Grillby
Patryck- Greater Dog
Paul- Doggo
Judy- Napstablook
Oc- (whatever role you want to be)

I couldn't decide which role some of these characters should take so i put second on there for some, if you want one of these roles, then you can. They'll play out first or second role.
