Resurrect Past Villains

Given that the completed Infinity Gauntlet will grant Thanos control over reality, there is every chance that he could bring back villains who had seemingly perished in order to have them work as his henchmen.

In particular, he could bring back those villains who had previously sought out or utilised the Infinity Stones – the likes of Red Skull, Malekith, Ronan and Ultron.

Of course, in Red Skull’s case, he probably isn’t even dead, so Thanos could just bring him back from wherever he is. And in Ronan’s case, Thanos might bring him back to life just to punish him for his attempted deceit. Malekith seems unlikely for commercial reasons – he just wasn’t very interesting – but there are rumours that Thanos actually masterminded the creation of Ultron, so even the robot could be brought back to operate at the Mad Titan’s side. It’s a frightening thought!
