Should Dragon Ball Fans Read Jaco the Galactic Patrolman?

When Dragon Ball Z: Resurrection 'F' came out in 2015, many fans of Dragon Ball were exposed to a character they hadn't seen before. The character in question was a diminutive but surprisingly strong alien named Jaco, who was introduced to the Z Fighters by Bulma and helped them battle Frieza's forces on Earth. The same scenario plays out with slight differences in Dragon Ball Super. But who is Jaco, and where has he been all this time? And why does Bulma know another alien?

Much as in the case of Dr. Slump's characters appearing in Dragon Ball and Dragon Ball Super, Jaco's appearance in the Dragon Ball storyline stems from another of Akira Toriyama's works. In 2013, Toriyama started writing and eventually released a single-volume manga, Jaco the Galactic Patrolman, with the titular alien as its main character. What isn't revealed until the bonus chapter is that the series is a direct prequel to Dragon Ball.

Jaco is a stereotypical-looking alien who stands at 4'10 and claims to be a «Super Elite» of the Galactic Patrol, which serves the Galactic King and polices the galaxy. This puts them in conflict with the stronger Saiyans and Frieza Force, and it is the impending arrival of a Saiyan (later revealed to be the infant Goku) that brings Jaco to Earth in the first place. While no match for a grown Saiyan (his own words), Jaco is incredibly strong by Earth standards, able to easily beat up regular humans, lift his own spaceship with ease, and even kick a giant rocket a great distance. He also possesses an extremely powerful blaster and an «extinction bomb» which can erase all life on a planet. Finally, Jaco is able to fly briefly by igniting his rocket boots.
