Zenyatta is an omnic monk in Overwatch who can heal allies and debuff enemies. His support abilities are semi-passive, like Lucio, but he targets individuals instead of dealing with a group. His ultimate is also a very powerful one that can save the entire team.
Zenyatta is interesting to play and, in my opinion, has some of the coolest looking animations. If you want something different and like to support your team in various ways, this character is for you. I'll go over some basic info and give tips for playing the monk, Zenyatta.
Zenyatta was a part of a group of omnic robots that experienced a spiritual awakening after the Omnic Crisis. They established a monastery in the Himalayas and abandoned their old programming. After meditating for years, they believed that they had souls, just as humans do.
This led to the leader, Tekhartha Mondatta, to seek a way to mend the relationship between humans and omnic robots. The method chosen was that of global teachings and the monks became celebrities.
Zenyatta believed this was not the way to mend the wounds of the past and instead wandered the world for personal connections between omnics and humans.
He sought to help others overcome their troubles and find enlightenment, with Genji being a prime example of one he has helped.
Zenyatta is a support character, so your main job is to heal and help your team, rather than deal damage. He is a harder support to get used to because of the nature of his abilities and weapon, but can really help the team once you get the hang of it.
