[Funny Trope] Evil, intimidated looking characters but actually very polite and have normal guy voice
Gorthan (Tom and Jerry: The Fast and the Furry): Aka The Destroyer of Light. Despite his intimidating appearance, Gorthan is actually gentle and shy person who owns a flower shop and greeting card store in mysterious land of Niltor. His car is charged by a thousand souls btw and he also love his mom, aww.
Hedoro (Gintama): The parody of my neighbor Totoro but instead of getting a cute fluffy character, the main cast got this beast as their new neighbor. Despite his appearance, he actually very polite and runs a flower shop, and he values all life and will stop people from hurting nature (though sometime he couldn't control his strength which could make people break their bone for stepping on a bug)
Red Death (The Venture Bros): Tbf, he only did his evil voice in his work time lmao. But outside work, he will be a normal suburban dad and pretty much chill and polite unless you try to mess with his family, that's all
