I read this scifi/Greek mythology graphic novel I read a few years back ~2013-14. The main premise was that the Greek gods were actually a space-faring civilization from a different dimension, while the Titans were criminals who were to be imprisoned in a pocket dimension. Something went wrong, bringing them all to this dimension, crash-landing on our world.
In the accident which lead them all here, they were all affected by a kind of radiation, leaving them all with unusual powers.
Titans spread out. Greek gods hunted them down, trying to protect humanity.
It is a sci-fi twist to the Greek mythology we know. It was a free web-comic/graphic novel I found online. 2013-2014 was when I came across it.
