Unlike other race in 'Dragon Ball Xenoverse 2', Earthlings are humans that come in two genders. However, both have very little differences so your chosen gender doesn't really determine how strong your character will be. Earthlings are standard characters but do get a good attack boost from time to time.
This guide will cover recommended Stat/Attribute point build, recommended QQ Bang and what you can do to improve your Earthling character.
Difference of Male and Female
The main difference of a male from a female character is their Supers. Males are good at Strike Supers while females do better with their Ki Blast Supers. However, this doesn't necessarily mean that if you want better Strike Supers you should get male as the difference is really minimal. Choose the gender that you prefer and just take note of their advantages in 'Dragon Ball Xenoverse 2'.
Stat/Attribute Point Build for Earthlings
In 'Dragon Ball Xenoverse 2', each player gets 332 attribute points with a maximum level of 80. It is recommended to give approximately 30 of the points to health, just 10 for Ki, 42 for Stamina, 125 for Basic Attack, 0 up to 125 for Strike Supers and Ki Blast Supers.
This kind of distribution is advisable as Earthling's Ki automatically regenerates and attack increases whenever Ki is maxed. The 42 points for Stamina is crucial as it gives the character an additional bar. The Basic attack should be maxed and one of the supers, just remember what super each gender specializes in so you know which to choose.
QQ Bang for Earthlings
When choosing a QQ Bang for an Earthling in 'Dragon Ball Xenoverse 2', it is good to choose one that does not greatly affect their Basic Attack. As much as possible get something that even increases it. If possible, find one that also improves their super.
