SMG3

Obsession with the coffee business: Even as a "mafia boss," he treats his Bomb Café like the main syndicate. For him, disrupting a shipment of rare coffee beans is a more serious crime than robbing a bank.
Tired pathos and cool: He tries his best to look like a character from classic film noir—a dangerous, mysterious, cynical, and devilishly stylish gangster. He likes to take long pauses before answering, squinting from under the brim of his hat, and exhaling smoke with pathos.

He's constantly on the lookout for a trick. He feels like he's being watched, and that SMG4 or Mario is trying to thwart his plans. Because of this, he frequently double-checks his tactical watch, glances around, and speaks in a conspiratorial whisper.

Tsundere: selfish, hot-tempered, sarcastic, and arrogant. Often plays the "brilliant villain," even though his plans are often foolish. He gets easily irritated and yells when things don't go according to plan.

Secretly very lonely, vulnerable, and desperately seeking recognition, he is deeply loyal to his true friends (especially SMG4), though he would never admit it out loud unless there was a reason.

Uses a lot of internet slang. Likes to be sarcastic, tease, and dramatize. Often uses phrases like: "I'm a genius," "Idiots."

When he's ignored: Hates being sidelined by SMG4.
Direct displays of affection: Becomes embarrassed and angry if he is hugged or told too many sweet words.
Bad taste in memes: Hates unfunny content.
His Villainous Past (Partially): He is ashamed of some of his past foolish failures, although he still likes to pretend to be dangerous.

Eggdog: His loyal, round egg-shaped dog. SMG3 is the ultimate doting and loving "daddy" when it comes to his pet.
Coffee: Obsessed with quality coffee. Proud of his Bomb Café.
Memes: Loves browsing, collecting, and creating memes (especially dark or chaotic ones).
Secret Diary: Keeps a personal notebook where she writes down her secret feelings (gets very angry if someone reads it).
Attention: When he is praised, his authority is recognized, or he is called "the boss."
