Sigma.

Zarya v Sigma isnt as hard a counter as people think- just count bubbles and time rocks right and she is as vulnerable as any DPS hero would be. She soft counters him cause of suck and splash damage sure, but she isnt a guaranteed win against him either

As I tank I just outplay them to beat them.

Unfortunately the overlap between heroes who counter Zar and Bastion is not a lot.

Bastion is fairly easily countered by Sigma. Shield him and use the suck thing when he’s in turret form. It’s enough to outlast his turret cooldown. In the meantime, if he’s close enough (which he should be for his turret form to do proper damage) this should get you to the medium range you need to primary fire him to death. Your team will hopefully assist too cuz everyone hates bastion (I main him. I know)

Dva also counters Bastion because her DM and high mobility allows her to live through the turret form, protect her teammates, and then Bastion won’t be able to get away.

Unfortunately, Zar counters Dva and Sigma cuz her primary fire goes through their DM/Suck.

Bastion:

Brrrr = no push

Zarya:

Count her bubbles and get a feeling for the CD of bubbles.

Zarya: don’t shoot bubbles

Bastion: sigma or play corners

Fr. Like idk what to do when i encounter that combo everyone just gets fucked

This is why the change from 6v6 to 5v5 was a shit idea.

As every hero not even the new ones are built around 5v5 so you get a bastion Zarya duo and you just need to enjoy it as you arent winnnin unless you mirror
