Techno-Barbarian

Most techno-barbarians are slaves that have been enhanced to provide a bio-mechanical wrecking ball for their masters. While most techno-barbarians are slaves, there are some exceptions to this. Some professional warriors take these enhancements on purpose to become more aggressive in a fight in order to gain an upper hand. Rigged with a mechanical pump filled with dangerous artificial hormones, these warriors can activate a crazed state that significantly enhances their physical abilities. Whether by choice or force, you have become a raging warrior fueled by a concoction of chemicals.

Chem-Fury

At 3rd when you choose this path you are fitted with a hormone pump that fuels your rage on command. Whenever you are raging you deal extra damage on all melee attacks equal to your Constitution modifier. 

Ambient Rage

Starting at level 6 you exude an aura of rage. Subtle twitches, sneers, and growls are a manifestations of this. Whenever you make an intimidation check you can add your Constitution modifier to the roll. Also, during combat while you are raging, you can roll an intimidation check as a bonus action against all enemies in a 10 ft radius. On a roll of 17 or higher all enemies in the radius roll disadvantage on all saving throws and attacks until the end of your next turn. You can use this ability in combat once per rage.

Trace Chems

By level 10 your continued use of chemical stimulants has left residual chemicals in your system that boost your physical abilities. You can a +1 bonus to all attack, damage, and Strength checks while not raging and your speed increases by 5 feet. 

Chemical Endurance

By level 14 your body has learned to react to the stimulants in your chem pump. Whenever you activate your rage you gain temporary HP equal to your Barbarian level plus your Constitution modifier until the rage ends.
