Nok Character Facts

Nok is a contestant in the 28th World Martial Arts Tournament. 
In the first round of the tournament, Nok is set to fight Vegeta. During the warming up, Nok comes up to Vegeta and tells him about how he will lose, that Vegeta is an old man and so on. So Vegeta, without even turning around, lightly backhands the young punk and sends him flying across the arena and into a wall. Nok "forfeits" the match (Vegeta convinced the officials that Nok was forfeiting the match, even though Nok never said that)[1] and was carried off in a stretcher by the medics. The rest of the Z Fighters were amused, Bulla was impressed with Vegeta's strength, and Bulma was upset that Vegeta had to act so soon to do so, preferring that he at least wait until they actually faced up.
