JoJo before JoJo: or Fabulous Magic Kung-fu Goblins and Weaponized Life Force

Some of you may or may not be familiar with JoJo's Bizarre Adventure. The early installments are summarized as huge muscled martial arts striking bizarre and almost impossible poses while using life energy to punch vampires and SUPER vampires. This is a JJBA image macro:

Now compare the above to this, from the Deities & Demigods supplement for Advanced Dungeons & Dragons;

 

As you can see, Maglubiyet is also pretty fabulous in the posing department. As the creator of Goblins, it seems like his creations would take after him.
So what about Goblins that are some form of bizarre magical martial artists? If based on JoJo's concept of weaponized life energy then Goblins could perhaps be a race apart from all others, supernaturally linked to a plane or dimension of life force.
Maybe they never die of old age like Tolkien's Elves. They could be walking bombs of "positive energy", anathema to the undead. Maybe they have innate healing powers.
Another thing worth considering is if non-Goblins can learn their mysterious martial arts. It could just be plain impossible, making Goblins the kung-fu race of the campaign world; it could be partially available but Humans/Elves/Dwarves/whatever lack the link to the mysterious "life-force" and must content themselves with mundane techniques; or it could be possible for anyone to learn with a healthy dose of hard work and guts.
