Detective Conan
Shinichi is forced to ingest the lethal poison APTX 4869 after an encounter with Gin and Vodka, agents of the mysterious Black Organization, while they were having a secret deal in an amusement park. Due to a rare side effect, the poison did not kill him. Instead, it shrinks him into a child and he adopts the pseudonym Conan Edogawa to hide from those who poisoned him.
Conan is a small and fast character with rapid attacks, optimal for a speedy playstyle.
