1. Annoying Dog (He technically created the game...)

2. Temmie (I guess? She works with Toby so...)

3. Asriel (infinite attack and defense; and that's just God of Hyperdeath)

4. Chara (deals 9 x potentially infinite damage with a single hit)

5. Flowey (Both versions; save, reload, and crash. He could kill you forever)

6. Sans (Think Papyrus on Steroids x broken 4th walls.)

7. Undyne the Undying (She is the only boss in Genocide that doesn't die in a single hit)

8. Asgore (No Mercy Toriel x2)

9. Toriel (Think of what would happen if her attacks didn't avoid you)

10. Mettaton (Almost indestructible in his (or her?) box form)

I could have put Napstablook in no. 3 since he is incorporeal, but if he had a body I don't think he will be in the list
