Thanos's infinity stone gauntlet is left-handed. The one that the Avengers make in Endgame is right-handed. Is there a significant or symbolic reason for this?
I'm interested in in-universe or out-of-universe answers. And I completely understand the answer might simply be random or even unconscious decision making by the film-makers. I just found it curious and wondered if there's anywhere that it is mentioned.
If you look closely at the scene where Hela is next to the (fake) infinity gauntlet in Odin's vault, you'll see that the gauntlet is right handed.
I'd say that there really isn't anything significant about the gauntlet being left or right handed, Tony was right handed and so it was probably a natural decision for him to put the stones on the right hand of his armour.
It's most likely down to personal preference, as A J♦ suggested, maybe Thanos really was left handed and preferred to have the gauntlet on his left hand.
Talvez the dwarves made the gauntlet left handed because that was the mould they had, or it could have been the only mould left for the gauntlet after they made Odin's right handed gauntlet.
Either way, Tony, Bruce and Thanos were the most powerful beings in the universe when they had the glove, I highly doubt they were paying attention to what hand it was on.
Marvel movies have been playing at Tony's left arm constantly getting hurt. Pretty much every movie in phase 3 has it written in the script along with him babying it. The gauntlet is obviously mostly his design, I'd like to think he wanted it to be right handed just in case he had to use it himself. I've only seen Endgame once but they don't seem to reference his left arm in his last movie at all. (unless i'm right about the right handed gauntlet)
Also most people (Avengers) are right handed...
