in the overwatch2 what is most op hero?

I think it's Kiriko. she can deal with enemy dealer, has lot healing, and his ultimate is very good in combination with other heroes.

Depends on what you're looking for

Tank?
Orisa, Zarya and Junker Queen

Damage?
Bastion, Sojourn, Soldier, Cassidy and Hanzo

Healing?
Moira, Ana and Mercy

A good ana can bully alot of players
