First of all I want to say that I’m really hyped for this game and that it uses a lot of obscure Greek mythology pearls already!
Me being a monster-addict however, I still have a lot of names and creatures for you to eventually add to the table, some probably not the way Greek Mythology has intended them, but since Geryon already proves this isn't necessary I can play with some of the monsters appearances in the way I would enjoy them in this game.
The top 10 of monsters/titans/gods I still like to see one day in this game (from best to worst in my own opinion) is:
1:
ArgusThe all seeing Argus is a giant covered in more than 100 eyes, I like this monster to be very monstrous or even non-humanoid, probably much like a Beholder. Its abilities and powers are about true seeing and sight of course.
2:
LampadDark Nymphs of the underground, they bring madness, sadness and insanity with their torches with purple flame. They have ties with Hecate.
3:
Empusa Another unit that has ties with Hecate, these are mostly succubus like demons in the real Greek Mythology, but since there is a real-world Mantis insect called after them and since God of War uses them as mantis-women, why not turn them into half mantis and half women here as well? It really suits them as MAN-eaters. And we already have a succubus-like unit in Gorgons, so I would vote for a mantis monster in this game, greek mythology doesn’t have much mantis monsters otherwise and a Mantis-like Centaur is awesome, of course Empusa also have flaming hair, turn the flames green to suit the Mantis theme.
4:
KarkinosThe giant blue crab that helped the Hydra against Herculus, when it was crushed under Hercules boot Hera took pity on it and turned it into a star sign cancer. I miss a cool giant crab unit in this game, it can be turned very monstrous.
5:
Skolopendra No centipede in Greek Mythology? Think again, the Skolopendra is awesome, it is a giant sea centipede horror not unlike the Vietnamese Con Rit.
6:
Chrysaor When Medusa was killed her blood didn’t only spawn Pegasus, it also spawned the evil winged boar/boarman Chrysaor. This demon is coolest when depicted as a boarman with golden armor and a golden whip weapon. His greed, lust and envy is legendary and his blood spawns swarms of Scorpions. Killing this badguy without being covered with scorpions isn’t easy. His death throw move could be awesome as his heart could maybe mutate into a giant Scorpios scorpion which bursts out of the corpse of Chrysaor and attack its fathers killer.
7:
Furies or Erinyes There must be three of them like in the real myth, these angels of vengeance could be awesome like in God of War which turned them into true monstrosities.
8:
MakhaiThe demons/Daemons of war that fight for Ares. I like them to be like in the movie Wrath of the Titans, where they are deformed demonic twins, sharing only one set of legs, they dance into battle and can’t be surprised from behind as they have a body on both sides.
9:
Chrysomallus The Golden Ram of the Golden Fleece, this could be a cool living battering ram type monster with giant golden horns much like the mythological monster Musimon.
10:
CercopesTwin thieves that gave Hercules a hard time, they were punished and transformed into monkey-men. In the game they could be awesome twin-minions with a twin-mind and when one of them dies the other goes berserk, they are of course also very good thieves and their powers could resolve around that.
Other monsters that are also cool enough to use:
Amphisbaena / Dactyl / Hekantoncheires / Hippocampus / Nosoi / Odontotyrannos / Peryton / Thriae / Akheilos / Narcissus / Phobetor / Proteus / Symplegades or Plankta / Agrius / Blemmyes / Celedon / Charon / Dryad / Eros / Erotes / Eurynomos / Ipotane / Keres / Lamia / Mares of Diomedes / Orthrus / Sybaris / Telchine / Triton / Scorpios / Ceryneian Hind / Maenad / Mormo
The way I would like to see the mysterious Odontotyrannus/nos.
Thanks for reading, and I hope I didn’t make too many English grammar/spelling errors. :-)
