After an extremely dangerous task given to him by a Chop shop he's sold many stolen vehicles to.
His mission here was to find a way to steal an M1a2 Tank
From a military base For a goos pile of cash but Richtofen never cared much for the money he had a legitimate death wish.
Getting paid for his skills to him is just a refund for not being able to kill him... Well to bad for him during this mission he learnd saiyans are very resistant to bullets.
Hell those little cuts on him are not paper cuts there actually from 50 cal. BMG rounds.
And it seems hes been followed.
