Which version of Tyrant? RKT beats depowered Tyrant. Fully powered Tyrant is near the equal of Galactus and therefore way above even the most powerful Skyfather.

Full powered Tyrant would destroy him. If its the depowered version then id give the edge to RKT using Thanos' bouts with Odin and depowered Tyrant as a means to decide.
