[Marvel] Could Thanos nullify Thor's attacks by using the reality stone to make him not worthy to wield the hammer?
gpt
Currently, Storm Breaker doesn't have an enchantment on it, and it can be assumed that after Odin died the enchantment he placed on Mjolnir also faded (as the magic he was using to imprison Hela also unravelled). 

BUT assuming that Odin is still alive and Thor is facing Thanos with Mjolnir, I'd say probably Thanos could make Thor unworthy. Odin doesn't have great feats, especially for his magic, the Reality stone is probably much more powerful than him.
