This was all done by my friend and it all makes sense in a way.

Basically cypher in game has a voiceline stating "I am Prometheus and you are just a god" a little bit of background knowledge Prometheus was a titan who sided with the gods in titanomachia because he can see glimpses of the future. This looks to be a fun little detail because Cyphers ultimate helps predict the future movements of the enemy.We can also take prometheus bringing fire to the humans as a symbol of cypher bringing knowledge about the enemies to his team. But if we pry deeper we see him talk to the radiants as they are gods. We can take this as the radiants being gods and the agents who rely on radiant tech to be titans. We can use this to correlate each agent to a god or titan. Also Cypher being prometheus also makes sense to why he dies every cinematic. He has to live in suffering just like Prometheus with his liver being torn out. This may also go past greek mythology and spread to different mythologies as well.

Right now the agents I think that are correlated to gods and titans are:

Cypher-Prometheus, due to his voiceline, him dying all the time, and giving information to his team

Omen-Hades, Omen has been strongly associated to with death and darkness with his abilities. His ult also lets him teleport, but he is in a shadow-like form. His blind and smokes create darkness and his teleport unravels him like shadows and re assembles him from the shadows again. He also has this voiceline to sage, "Sage the life you give do you ever wonder where it is taken from?" This shows that omen may have seen the realm of death and the dead souls just like hades who rules the underworld.

Skye-Demeter, Due to skyes power being with nature just like demeter. Demeter can also be cruel during the winter and Kay/o tells us that he has seen the future where skye grows and just like demeter skye may become even more deadly.

Sova-Artemis- This is an interesting one because Artemis is a half titan born from Leto and Zeus, Sova has been related to the hunt such as him stating, "I am the hunter" Artemis also being the goddess of the hunt. Sova also has radianite in him with his eye which gives him the "half god" aspect and uses radiante tech giving the "half titan" aspect. Sova also uses a bow the preferred weapon of artemis.

Brimstone-Atlas- This is mainly because of the ways brimstone is depicted in the die for you video, he is shown holding a sphere of something on his back. Atlas being cursed to hold the sky is a direct comparision to brimstone.

Jett-Hermes-This was a quite simple one because hermes is known for being fast and the gods messenger. Jett also has the wind and what can be faster than the wind

Neon-Zeus-A simple one again uses lightning who else uses lightning in the gods but Zeus

Phoenix-Apollo-This was a tricky one because using my previous logic phoenix cannot be apollo since he is a pure radiant no tech involved, so I was wondering could phoenix perhaps be hephaestus due to hephaestus also using fire, but then remembered phoenixs ultimate. Due to phoenix rising from the ashes after dying like the sun after setting he should be Apollo. Also because the sun has a set cycle every day it makes sense why his ult expires since the sun doesn't just hang in the sky. Another fun fact phoenixs have a place in greek mythology as being a symbol for the sun so even more proof.

Chamber-Hephaestus-Chamber contradicts my previous logic as well because chamber is not a radiant. But the support for chamber being Hephaestus is strong. Chamber as you know is an arms dealer and he selles weapons. Also hephaestus is known as the gods blacksmith. Hephaestus does hate some of the gods though and this might be why he is represented by a non radiant. But I have read somewhere that chambers real name translates to young blacksmith which adds on the the theory of him representing hephaestus or going the other route, chamber could be a cyclops due to him not being a radiant and not one of the "gods". The cyclops are also master blacksmiths, but going with the greek mythology the cyclops' helped aid the gods so this may mean chamber works with the radiants in the radiant war.

Edit: as many people pointed out in the comments neon isn't a great fit for Zeus and we realize it was quite a stretch. I will update some of the current agents and add some more to the list as well.
