I know Hercules has some respect for Zeus as both his father and king and often boast about being the son of Zeus, but I sort of have to wonder how much. Zeus isn't exactly the type of father you can look at and say with pride "This guy is my dad!" Whenever Odin disappears, Thor more often than not has searched the entire universe and beyond looking for him. As much as the two butt heads Thor a deep love and respect for Odin (at least under most writers.) When Zeus died, Hercules knew exactly where he was yet was content to leave him there. None of the Olympians including Hera or Athena were eager to retrieve Zeus. And those three are probable the closest and most loyal to Zeus of all the Olympians. Hercules respects Zeus, but how much seems to vary much more than the Thor/Odin relationship.
