Beat

Beat (ビート, Bīto), the Saiyan Hero, is a Human who utilizes the advanced time travel technology of the Dragon Ball Heroes machines, allowing him to become a Saiyan.[1][2]

The Saiyan Hero is the main promotional character, as well as a playable Saiyan avatar for the arcade game Dragon Ball Heroes.

Power
In his first ever appearance, Beat is no match Perfect Cell and gets overpowered by the Bio-Android. However he is shown to have no trouble handling Frieza's soldiers in his base form.

Upon first transforming into a Super Saiyan, Beat is outclassed by Legendary Super Saiyan Broly. Later however he is able to take on the Baby infected Trunks, Goten, Gohan, and Videl, defeating them on his own. He was also able to overpower Dodoria and Zarbon, being unphased by a direct punch from the former.

In his Super Saiyan 2 state, Beat proves strong enough to break free from Black Smoke Shenron's shadow tendrils. After using the Super Class upgrade Beat proves powerful enough to defeat Nimu (under the possession of Oceanus Shenron).

As a Super Saiyan 3, Beat appears to be around the level of Kid Buu after absorbing Southern Supreme Kai. However, even as a Super Saiyan 3 he is absolutely no match for Super Saiyan 4 Broly.
