DRAGON BALL: THAT TIME I GOT REINCARNATED AS YAMCHA

Based on Dragon Ball by Akira Toriyama
Story and Art by dragongarow LEE

This goofball manga was published in Japan in 2017 and received an English-language release from Viz in 2018. I read it via "scanlations" when it was first released, and liked it so much that I bought Viz's digital edition. It's the story of a Japanese teenager, who happens to be a huge DRAGON BALL fan, and who is accidentally killed when he falls down a flight of stairs -- only to wake up in the DRAGON BALL world, reincarnated in the body of Yamcha, circa the end of the initial DB story arc, the "Pilaf Saga".

Our protagonist pretty quickly adjusts to his life, and what follows is a three-chapter storyline in which he uses his meta-knowledge of future events to his own advantage. The story skips straight past all of DRAGON BALL (after establishing that Yamcha is going to train with Master Roshi alongside Goku rather than travel to the Western Capitol with Bulma), and jumps to the Saiyan Saga. We learn that Yamcha has climbed Korin's tower and trained there, and has even borrowed Piccolo's spaceship to fly to planet Namek, where the Great Elder of Namek unlocked his hidden power and he trained with the warrior, Nail. Because of all this, Yamcha is able to fight alongside Goku and defeat Vegeta.
