Random info:
Ranma:
Ranma can summon things other than Godzilla, but if he summons animal it's always godzilla, and if he summons objects there is still a chance Godzilla will tag along.
Ranma at some point went berzerk and killed everyone that ever wronged him, and some who where just trying to help. The cause was the Sailor scouts from the Anime loopverse trying to summon him for sex causing him to finally snap from being considered just a fuck toy buy the female awakened.
Ranma has the best relationship with Skuld, Lina Inverse, Usagi Tsukino (manga), and Nabiki. The latter too are mostly considered friends while the former are closer to serious lovers.
Ranma has some blank space in his memeory from before the fused loops from when he was really going insane.
The numbers of the Nanoha loopverse are his adopted daughters. Note #s 1&3 are more like lovers. Note2 This is after stint as Ranma Scrya which was his first contact with the Nanoha verse.
Somewhere in the multiverse there is an Alt.Belldandy, that was called by Ranma, who is crying because everyone forgot she excisted.
