Frost was one of my favorite villains on the show. He is basically the Frieza of universe 6. We are led to believe that he’s good instead of evil.
Everyone is shocked to see that Frost defeated Goku during the tournament against Universe 6 and 7.
But he really is evil, he used a trick of poison to defeat Goku. He tries to make it seem like he won fair and square.
Vegeta however never trusted Frost, and when it was revealed that he cheated, Vegeta has no trouble defeating Frost in battle.
Frost eventually meets Frieza during the tournament of power. It was Frieza who got the upper hand on Frost.
And Frost becomes one of the first eliminated for Universe 6 during the tournament of power.
Frost gets so mad at Frieza, that he tries attacking him outside the ring.
For that, Lord Zeno erases him from existence. When Android 17 brings all the universes back to life, I don’t think I saw Frost. So he was really the only casualty during the tournament of power.
