Well, there is a chance that the Medusa is species artificially created by Scientists, but to be honest, I cannot think any reason how, unless it was only women Scientists. These Medusas are aggresive(as their mythologian counterparts) only against men, but the Entvined Soldiers are aggresive against woment too.
Maybe they were created by the scientists in Jobe. Thats the only possible explanation. But, I still believe that they are "E.T`s". They seem both advanced, yet simple, as their Enigma counterparts.
They follow their myths closely, and yes, that is one of the arguments why they are created by men. But it is clear that they ARE a threat, since so many Omni Tek Soldiers has been abducted and seduced, and turned into wicked guardians of the Medusa`s. The soldiers are wearing Omni Tek Armor, with the logo on, which makes me believe this. The armor and themselves seems twisted and modified by the Medusas.
Yes, we live in a world built upon myths. Avalon, Tarasque, The Versailles Tower(Dont remember the spelling right now), Galahad and Pit Lizards all refer to the world men dreamt of before.
Did Omni Tek create Tarasque too? Why is she the only pure dragon left?
Still I choose to believe that at least, the Enigma`s and the Medusa`s dont belong to Rubi-Ka.
