SPOLIER: Bad Endings
-Thanos gets too emboldened by use of the Reality Stone and starts acting like his Sacred Timeline self.
-Hela returns to Asgard with her revived Fenris and has become the vicious warrior her father wanted. He immediately regrets it.
-Steve Roger's gives the Power Stone to the USSR but they use it to power weapons.
A spell known as the Hand of Agamotto can allow Infinity Stones to work outside of their universes; unlike how Infinity Ultron could only use his on himself. Thus allowing the Hero of the Multiverse their full power.
