Something interesting in Primal (2019 animated TV series)

For those of you who didn't watch any episode of Genndy Tartakovsky's Primal (2019), this will contain spoilers for episode 5 "Rage of the ape-men". I do recommend the show if you're a fan of Genndy Tartakovsky. The show itself is brutal, I love it.

What exactly happens in episode 5:

So in episode 5, a caveman named "Spear" and a female T-Rex named "Fang" reach oasis and decided to rest there. They are soon captured by the tribe of ape-men and are taken away. Sometime later, Spear wakes up all tied up in the fighting area where gorilla warriors fight and the champion is given a drop of the black substance by the elder, which mutates him and enhances his strength. They release Fang into the area, Fang tries to fight but she is no match for the gorilla champion. Spear frees himself and tries to help but is knocked away. Spear then climbs at the top where the elder is, throws elder away and drinks all of the black substance. Apemen attack him, but he quickly mutates, knocks them away and jumps into the area. Gorilla champ attacks him but Spear sends him flying with a single blow. Gorilla champ recovers and charges at Spear, but Spear tears off both of his arms and beats him to death as other apemen watch in disbelief. They all jump into the arena and attack Spear but he obliterates them all. Sometime later, he mutates back into his normal form.

What I find particularly interesting about this certain episode? It's the black substance that caught my attention, it reminded me of the black goo from Prometheus. And as soon as I saw gorilla and Spear mutating from the substance, I thought of mutated Fifield from Prometheus and the mutated Yautja from AVP Fire and stone by dark horse comics.
