The Italy-inspired region of Purore (from “puro”, the Italian word for “pure”, and “cuore”, the Italian word for “heart”) is a vast landscape and is one of the most diverse regions in the world in terms of its Pokemon population. In addition to the region being where the new Love type was discovered and researched, the type diversity is enormous, and the Pokemon of the region exhibit a huge array of different pure and dual typings.
The leading Pokemon professor of the region, Professor Oleander, is an expert "type biologist", being the one who first defined and classified the Love type, soon made a discovery that explained this huge diversity - Purore is a hotspot for powerful Typergy Crystals.
Typergy is a lifeforce that runs through all Pokemon. A Pokemon draws its type's power and attacks from its internal Typergy. However, Professor Oleander discovered that when a Pokemon comes into contact with the mysterious Typergy Crystals that match up with their typing...they become capable of externalizing their own Typergy and taking on all new Typergy Forms!
Typergy Forms are special new forms of specific Pokemon that draw out the power of a specific type they have. They lose their other typing and become pure-typed if they are a dual-type Pokemon (for example when a Greninja uses a Dark Typergy Crystal, it becomes a pure Dark type and loses the Water type). However, this grants them access to powerful Typergy abilities, which give them different boosts based on each type they have. And here are all 19 of them!

That Pokemon also gains Affection benefits, as do all allied team members. Normal type moves become Love type.
VGC will never be the same.
Last but not least, this is an example of a Typergy Form. I'll figure out other Pokemon that'd get these forms as I go along!
