Here is an overview of the character, via the game’s official website:
Venom (voiced by Junichi Suwabe in Japanese, Howard Wang in English)
Easy to Use: ★☆☆☆☆
He is a gentle and honest man who can barely bring himself to lie. There is a rigidity to his speech that suggests he favors reason above all else, but in fact, he places high importance on emotion, empathy, and humility.
During the battle with Bedman, the leader of the Assassin’s Guild Venom dies—to the outside world, at least. After Robo-Ky saves his life, he attempts to fund his repairs by taking any work he can get, until Zato gifts him ownership of the store where he opens his bakery.
Through his new life as a baker, Venom learns of a new and unfamiliar “battle.”
He grows fond of the townspeople who fight not to take the lives of others but for their own pride, and swears to protect their “battlefield.” And so begins his new battle: baker by day, mysterious punisher “Phantom” by night.
