1 A sailor moon story with a slightly different adversary: There was a
parallel dimension that was being decemated by a incredibly deadly plague.
There was no cure, no way to protect against infection, just the entire world
dying slowly. However a scientist working on a cure accidentally opens and gets
pulled through a dimensional rift, and since this happens at the same moment
Princess Serenity used her Moon Healing Escalation to destroy Metalla he is
cured in the proccess. Not knowing about Princess Serenety he dives into the
question of duplicating the cure, and as fialures start to mount he gets more
desperate. Naturally he accidentally discovers that Human Energy slows the
progress of the plague early on, but he needs to find the cure which is the
Silver Crystal.
2 Genma seemingly is possesed. As it turns out he was actually a deamon
all along who simply sealed himself in the most unlikely shell he could visulise
to hide from deamon hunters. Thing is he had left a triger to release him and
it's just been trigered. Ranma has to stop him, but most of the power he
unknowingly inherited from his father is sealed by the Nekoken.
3 A concept for 3x3 eyes and the Xena/Herculese universe. The Sanjiyan
origionated in another dimension. Long ago there was a great civil war there,
and the world was reduced to a lifeless burnt out husk. The survivors fled to
different worlds, and one group arived on earth. The earth of the
Herculese/Xena storylines. Anyways at first the gods just tried to observe the
refugees, then they started trying to incorperate them into ther games. Then
they discovered that when the Sanjiyan were pushed they could push back. Hard.
This eventually escalated into a war which explains why the gods have so
thoroughly butted out of human affairs.
