Pokémon Blaze Black and Pokémon Volt White are edits of the regular Pokémon Black and White versions which self-contain all 649 Pokémon, allowing a player a large amount of variety. In addition, BB/VW also have edited trainers, an increased difficulty level, improvements to many Pokémon and more. They are the spiritual successor of my two other hacks, Pokémon Fire Red Omega and Pokémon Spirit Gold. Blaze Black and Volt White were also - with one minor exception - the first of their kind to be made.
I should mention that with the exception of things normally different between Black and White such as Black City, White Forest, the legendary focus and the appearance of Opelucid City, the two games are identical.
