Alright, I've been reading this forum for a while now, but I've never actually posted anything, so here's my first go at setting up a fight.
Edwin Jarvis
vs.
Wong
This is Wong as he currently appears in The Oath miniseries, making the fight more even,(not currently on the top of his fighting game due to his symptoms)
Wong is a martial arts master on the level of people like Shang Chi. Even though he is sick, he still took out like 5 grown men with weapons in less than a second without even trying.
Wong does not know any combative magic; plus, Jarvis has fighting experience. He was an undefeated Royal Airforce boxing champion for two years. I personally imagine Wong would win this, but I don't think the fight would be immediately over.
