yes pretty much, everything mixed together for insanity, action packed, epicness.

By true form, i mean some beings under certain mythologies have a different form. Example: The Egyptian mythology deities usually have an animal type head along with a human body. While others have themselves being bigger and fully armored out of no where and etc... Now of course all the demi-gods can change their appearance, to fit what ever they wish, but only in their true form will they be at full power, which would be dangerous near humans, because they might be killed by their presence. Not to mention some Deities have special weapons that they created or had someone create for them.

When the event happens their bodies will be changed to fit this form. Which could turn one who was originally human into a Huge beast, or maybe turn what was a creature into a humanoid/human appearance. which again will depend on the character themselves.

There is a high chance depending on amount of people, a big chunk or all mythologies may be represented. now i personally don't know everything about every mythology so i can't speak about everything. i mainly know of Greek/Roman, Norse, and Egyptian.

hm.. lol you are very thorough which i like some. hm.. i don't have everything planned out as of yet, like the launch location or anything, though i should before to long, hopefully. If this can make it i'd be happy as heck, though i do have planned the beginning of the roleplay to take 2 years after the event. so they've had 2 years to get use to their new bodies, which some could of just not understood what was happening and complete avoided anything to do with what happened so lol.

For powers themselves, i will judge what will be allowed and not. mainly because can't have something that is entirely Unfair against everyone else, some may end up being a little unbalanced but it wont be entirely one sided if they was to run into each other.
