Essence ofGodzilla

You gain a free age and appearance change to whatever you want.

You have a database containing all the technological developments made by the various iterations of Godzilla humanity, such as the Oxygen Destroyer and Mechagodzilla.

You have also gained psychic powers.

Optionally, you may become a type of Godzilla/Toho Kaiju of your choice and gain their iconic powers and abilities of that type of Kaiju, such as Godzilla or Ghidorah. You can freely transform into your previous form and back if you want.

Optionally, you may have Kaiju appear in your world and worlds you go to. This may or may not include a Hollow Earth, up to you.

You may have any Godzilla characters or Kaiju of your choice become your companions and may choose what relationships/history you have or will develop with each of them (being lovers, friends, etc.), if any, meeting them in positive circumstances. You may also give companioned Kaiju human(oid) and human-sized forms as you wish (they can freely transform into Kaifu form and back). Yes, you may make them waifus if you want.

Optionally, you may Self-Insert into Godzilla or a variant (like a fanfic). You may choose when, where, and what world. The specifics are up you; maybe you get dropped in (default), maybe you insert yourself into or replace a certain character, maybe you get reincarnated, maybe you get merged with a local counterpart of yourself, etc.

If you Self-Insert into the above via an Essence or other means, you are guaranteed to meet the chosen companions in-universe (resurrecting them if they are dead by the point you enter the story, which may draw attention).
