Arc Zero

Arc Zero is an arc of the Thunderblaster D series and serves as the series' prolouge before the actual first arc.

Summary
The prolouge focuses on Doryu Kaminari growing up with his foster parents the Sturm family, after his father Shiro Kaminari goes missing while fighting Raiki 7 years earlier, and how the said protagonist starting to use the Thunder Crystal of his late mother to transform into the feisty, outgoing superhero. For now, he can only use boomerangs, as he's too young to use any other weapon nor he can fly at this age. Raiki remains as the series' antagonist, along with a young child named Fievel, who mimics anything he sees from television and video games.

Trivia
There was going to be a sprite comic based on Arc Zero, but eventually turned down due to the lack of ideas, it was later revamped as "Multi-Dimensional Children" as a seperated entry and a crossover. It does not interfere with the actual Arc Zero.
