Viltrumites live for the heat of combat, and when enraged can unlock their true potential. When you are below half of your total hit points, you gain a bonus to your Strength score equal to your Proficiency Bonus. This bonus can raise it over typical natural limits. 

Viltrumites are trained as incredible martial warriors, generally relying on their bare hands to tear enemies to pieces- which mixes well with their unnatural strength. Your unarmed strikes deal 1d6 bludgeoning damage. 

Your Strength score increases by 2, and your Constitution score increases by 1. 

As a Viltrumite, you slow your aging processes as time passes. You reach maturity at approximately the same rate as humans but live for approximately 1,000 years. 

Viltrumites are largely sent out as military units of a conquering empire. Typically, these scouts are lawful neutral, but many skew in favor of good and evil. Very few deviate from the philosophies of dominance and obediance.

Thanks to your highly advanced smart cells, you heal at a supernatural rate. Even without resting, if you have at least 1 hit point, you heal 1 hit point per round. This property doesn't function if you were hit by fire damage this round. 

You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.

You naturally adapt to hostile environments. You have resistance to negative effects of extreme temperatures ranging from -60 to 140 degrees Farenheit.
