The giant in the golden armor with a lizard skull on its hand reminds me of Saint George. Saint George is a military saint as he was a member of the Praetorian Guard for emperor Diocletian. The Legend of Saint George and the Dragon comes from tradition that tells of the mighty feat of killing a Dragon (in most depictions it's a Serpent) that was terrorizing the city of Silene (Libya) with his lance named Ascalon. https://imgur.com/EUXLRma

The most interesting part of all these is that Saint George is one of the Fourteen Holy Helpers that are attributed for helping, with their prayers, the defeat of illness, desease or epidemic most probably Black Death. (relating to all his talk about the vials with viruses or bacteria)

Further down the line, as part of the Fourteen Holy Helpers saint George was given patronage for the health of domestic animals, against HERPETIC diseases, and patron of soldiers. The most obvious herpetic disease is Herpes Simplex or commonly Herpes but what matters here in relation to the story is the actual word.

Herpetic/Herpes. Herpetic comes from Greek "Ερπετό"[Ηe-rpe-to(without pronouncing the H, Erpeto)] and from Proto-Indo-European Serp which pretty much means Serpent in English (see lingustic progression Serp, Ερπ(Erp), Herp, Serpent). Herpes also comes from Greek and shares a relationship with Herpeto and derives from "Έρπω"[He-rpo(without pronouncing the H, Erpo)] and pretty much means "Moving, volunteraly, with my whole body in contact with the group". The most accurate translation in English is crawl, which is what Reptiles/Serpents do.

Pretty fun correlations between all.
