Intros

The Intro is the beginning of the episode in which the theme song plays. It has been altered over the course of the series.

BFDI
The intro starts with all the contestants standing in the plains, looking toward the camera. The camera then pans to Dream Island, as the BFDI logo appears. It then cuts to black and shows the credits.

BFDIA
The intro is identical to the BFDI intro, except the landscape is a different shade and Dream Island is now gone. The logo apears like normal, but instead of cutting to black, "again" appears  below the logo and the credits fade in.

The intro was changed in Zeeky Boogy Doog, and read "Battle for Nothing" instead, with exclimation points replacing "again".

IDFB
The logo stars with the contestants outside of the LOL falling against a white background, changing between 1-3 different expressions. It shows their names above them. The LOL then shows the contestants still inside. The shot changes to the original layout, with the contestants standing in the foreground before the camera pans into the background, now showing Yolye City instead, with the IDFB logo appearing. The theme song is a remix of the original theme.

BFB
The intro starts with Four, before quickly showing all the contestants, who are organized by color. The camera then zooms out to show the contestants now on an unknown, monochromatic landscape, with Four and X standing in the background. It then cuts to the logo, with a picture of Four and X.
