Monaka was a decent joke character on Dragon Ball Super.
Lord Beerus introduces him as the most powerful mortal in universe 7.
But in truth, he’s really a delivery guy that Lord Beerus paid to be motivation for Goku.
And Lord Beerus freaks out when Goku comes close to discovering the truth several times.
To his horror, Goku loses to Hit and Monaka is forced to fight. Hit throws the fight and Monaka’s secret is safe.
