Champions with a lot of vertical mobility like Andro or Drogoz can counter her, as she cannot stay in the air for longand her attacks are projectiles, which are difficult to hit to a flying enemy.

Lex's Ultimate completely destroys Barik's Ultimate, so try to save it for the right time.

This matchup is extremely difficult, but try to make her waste her fire by going planted, then immediately switching to travel form. (note that you will still take much damage but it won't be an insta kill)

When Tiberius does his ult and jumps in the air, you can void grip him to break his immunity and have your teammates kill him.
