God Hand is easily the strongest Unknown character.
Anyway, I will do Equal and Unequal list.

2A:YHVH
2B: Equal is
Zeus (Saint Seiya), Unequal either Chara or Arceus.
2C: I don't know.... Chaos, Pontos and Lucemon are all incredible contenders. Though Pontos does get blitzed.

3A:
White Face Unequal, either it or the Downstreamers if Equal.
3B: There was a Saint Seiya 3B I don't remember.
3C:
Alphamo no question, I'm honestly amazed this thing hasn't defeated Reinhard yet...
4A:
The God Emperor of Mankind regardless of speed.
4B:
The God Emperor of Mankind again, although with Unequal it may have pulled an inconclusive against
Playable Caster (Tamamo-no-Mae), provided our old standard of immeasurable wasn't Axed.

6B:
Novel Kars Equal even without stands, Unequal whatever that Digimon was.
Low 6B
Mewtwo
High 6C:
Natsu Dragneel if Unequal,
Kenshiro if equal, and for the record, I'm aware of the match between them with Unequal speed, that should be removed ASAP.
6C: Whatever that immesurable Digimon was. Equal IDK, might be
YoRHa Type A No.2 once the upgrades go through, well every Nier Android.
