Apollo intrigues introduces Hercules to ambrosia, the food of the gods in Greek mythology. It could confer immortality to those who eat it.
Ariadne is the starter for the race between Apollo and Hércules, much like the attractive women starters in drag racing.
Kevin Sorbo is given a respite again, having only character-driven scenes. The action scenes are instead given to the Young Hercules.
This is the first time that Young Hercules appears but Young Iolaus doesn't. Instead, Young Jason takes his place.
The title Top God may be a play on the movie Top Gun (1986) which also features an unlikable protagonist who changes his ways to become a likable hero. Or it could be an anagram of top dog, an alpha male.
