The strongest Pokemon that Angemon would defeat in 1v1?

[Harpomon]

This is Adventure 01 Angemon at the time he fought Piedmon. Angemon & Takeru have full knowledge of each Pokemon but the Pokemon don't know Angemon, they just randomly attack him one by one and Angemon could heal after every fight.

Scenario 1) Angemon cannot evolve into HolyAngemon

Scenario 2) Angemon can evolve into HolyAngemon

How would these go?

Scenario 1) Angemon cannot evolve into HolyAngemon

Angemon outdueled Piemon and put him on his ass, forcing him to use his strongest attack (which broke WarGreymon's armour mind you) out of sheer desperation, said attack reflected Angemon's own Heaven's Knuckle back at him, then was hit by the attack AGAIN and was still alive.

Angemon gets minimum continent level, massively hypersonic (quad digit) scaling so he could probably take up to Xerneas/Yveltal/Zygarde or Reshiram/Zekrom/Kyurem before being crushed by the likes of Kyogre and Groudon.

Scenario 2) Angemon can evolve into HolyAngemon

He still gets the same scaling from being stronger than Piemon, the only real difference is having BFR in the form of Heaven's Gate. I still don't think he gets passed Kyogre and Groudon.
