The Destiny Gang is a ruthless gang shown in "Finn the Human" and in "Jake the Dog," led by Big Destiny. Other known members are Tromo and Trami. They wear avant garde clothing with flashy and surreal colors, to mimic Big Destiny. They terrorize the citizens of Junktown in Farmworld. The Destiny Gang demands payment from Farmworld Finn's family, the Mertens, whom they bully in hopes of receiving the money.
In the standard timeline, a different gang called the Bath Boy Gang existed, as seen in "The Vault." It is likely that they are normal timeline equivalents to the Destiny Gang, although they bear little resemblance.
