@guijojo Yes, it actually was. I had a lot of ideas for how it would end up going. The reader and Weiss would end up connecting in the elevator when she was going to make a call in the CCT Tower. They'd get together in the prom. At the end of Volume 2, the reader would turn into Godzilla Terrestris and stop the Grimm horde.
At the end of Volume 3, the reader would turn into Godzilla Ultima to fight and kill the Wyvern.
Throughout Volume 4, the reader would be travelling to Atlas in order to reunite with Weiss. Afterwards, he'd follow her throughout her adventures, occasionally using his Godzilla forms to save the day.
At some point, it's revealed that there was a prophecy. Ozpin and Ironwood were afraid of the reader because, according to the prophecy, he would assist Salem in destroying the world, and he would eventually be defeated by a Schnee. It's also revealed that he never had a past or a family. He's just this thing that exists.
After discovering the prophecy, Weiss would be afraid that she would hurt the reader in some way, leading to her eventually breaking up with him in Volume 7. This would lead to the reader meeting up with Salem, and her using his emotions to get him on her side. Throughout Volume 8, the reader would be rampaging as Godzilla.
At some point, Weiss would manage to talk to the reader and reconcile with him. It's realized that the prophecy never specified how long the reader would help Salem, or how a Schnee would defeat him, so the reader goes back to fighting alongside Team RWBY, and his relationship with Weiss is nothing but wholesome moments from that point onward.
