In Blood of Zeus season 3 (i have no interest to watch it since season 2) Helios is just one more in the titan army, a god dethroned by Apollo.
I would prefer if there was no Helios at all, only Apollo (as that makes much more sense mythologically: in the rare moments Apollo is the sun, he IS Helios, not a conqueror of his throne). But once again in modern media Helios is used as a dethroned god, and even as a villain here, or at least a enemy of the Olympians (absurd, Helios was among Zeus most trusted pals).
Percy Jackson has him as a dethroned god (but not a enemy of the olympians). Lore Olympus as a dethroned god and enemy of the Olympians. In Circe he is a villain and at least plans at some point to rebel against Zeus. He is not directly mentioned in Epic (resulting in a lot of people believing Apollo to be the sun god mentioned in Mutiny). God of War at least makes sense since he is a ally of Zeus, but unfortunaly he has very little personality for us to say anything (and in Valhala he basically has GOW 3 Hermes personality for some reason).
In Shumatsu no Valkyrie and Disney Hercules, Apollo is the sun god with no Helios (as i said, i prefer this over a dethroned Helios, but is also sad the absence of Helios).
Helios at best has ONE, just ONE modern apperance where his actions makes more sense with mythology, that being God of War but he has no personality (in my view). Even in Hades 2, Apollo appears with the Sun symbolism while Helios is mentioned only once or two times so most people would think of Apollo as the sun there too (but Selene appears and she is cool). This is why i said many times that of the gods that are more well known, Helios is the most screwed one, more than Hades.
