The Light is an unused mini-boss in Cuphead that would have been encountered in the All Bets Are Off! level. The Light can only be encountered in debug mode. The design for this boss is probably a placeholder and probably would not look like this, had it been finished.
Like the scrapped boss Card, the Light's design seems to not be finalized at all and is rather jarring compared to the 1930 cartoon style of Cuphead. It appears to be a green frog or lizard wearing a black hat, drawn using colored pencils. It has six light rays coming out of its body, and has two Jareeds next to it.
There are six blue light beams rotating around the platforms. Three of the lights will turn yellow, red and then back to blue. Red lights will damage the player(s) if they are not avoided. They will get progressively faster throughout the fight. Blue and yellow lights will not do any damage to the player or players when touched. For added difficulty, there are two Jareeds on the platforms that also deal contact damage.
The player would move around the platforms dodging the Jareeds and light rays, while shooting at the boss to defeat it.
This mini-boss does not have a knockout animation. Once it is defeated it will stay as it was in battle.
- This mini-boss was probably cut because the boss wasn't fully drawn by the game's release (given that, on average, a single frame in a animation can take up to 5 minutes), or the developers could never fully decide on a final design (the developers that worked on Cuphead were known to be perfectionists), leading to it's removal, or that it's "gimmick" was considered too confusing.
- Based on the locations of the Jareeds and the Light, as well of the "lights" coming out of the Light itself, it was presumbly going to be a disco ball with the Jareeds being placeholders for dancers.
- The Light may reference either light shows performed in casinos or the neon casino night signs.
