Firey is the cool winner of BFDI! He's a living flame and can burn people. Firey is rather dim-witted and forgetful. He loves to win but he also loves to be complimented, but he's hard to pin down. He's afraid of heights and crying, can run fast, and loves chocolate. Firey hates Coiny and always slaps him every day. Firey also has a secret crush on Leafy but doesn't know how to tell her. He also owns an island.

I'm a living flame who won BFDI.

You was launched in a big gray box.

Firey Jr. usually tries to be thoughtful and is protective towards his friends such as Bomby and Spongy. However, when talking to people he does not particularly know or care for, he has been seen to show insensitivity and borderline rudeness. He also seems to be very observant and an analyzer. When insulted, Firey Jr. gets very defensive and may talk before thinking.

I'm a kid!

The ghost is a floating ghost that can go through walls, the ghost cannot talk (cuz it's an Spelunky enemy duh), and if it touches you, you could disappear, so the ghost has 9999 health, you can make it lose a health by using a UFO from the Ice Caves or lava from the Temple. But the UFO only shoots one laser at a time so the ghost is impossible to defeat. Where did it come from? But from YASM a.k.a (Yet Another Spelunky Mod* It said "A Ghastly Voice Calls Out Your Name... Let's get out of here!"

The ghost is invincible and noclipable.

Firey and Coiny is always slapping each other

Four is a host of the show BFB, season four of BFDI. Although Four seems to be calm most of the time, they do get angry. They seem to be childish. They act like a control freak because they want everyone to stay with him forever. Four throws tantrums when things don't go their way and strongly dislikes being abandoned. They use their powers to harm the contestants just for their own fun. Four can screech at people and stun them, he can also shoot beams out of his hands. He likes X and hates Two.

Powerful, mysterious, best known for hosting BFB.

Two is hosting The Power of Two, a show where the prize is their limitless power. They usually show a friendly and optimistic disposition. They also like to show off their powers to the contestants, and even promises to give their powers to them only if they join Two's show. Two isn't devoid of negative traits as they can also be arrogant and somewhat sadistic. They grin smugly when the contestants leave Four, using their powers to attack them. Two is a more easygoing and casual host than Four.

The host of TPOT who stole Four's contestants.

X is Four's friend

Teardrop's personality has been shrouded in mystery as she is either completely mute or prefers not to speak. However, she is portrayed as competitive and is fairly intelligent.

A lot when she is lost, and the Damsel is a blond woman in red with yellow hair, and she kisses the player, giving the player an extra live.
