Big Boy

```
"A giant missile controlled by an AI, it's Nega Rainbow beams and command over laser planes make it a hardy foe."- Big Boy's Bestiary Entry.

```

**Big Boy** is one of the three bosses the player needs to defeat to access the Deepest Sector. The battle itself takes place over 3 phases:

**Phase 1** has the player attack Big Boy while avoiding it's Laser Planes and the Nega Rainbow Beams it fires out. **Phase 2** has the player warped below, having to either climb their way back up while taking down Laser Planes or using a tunnel to get back up. Either way, the player has to attack Big Boy while trying not to fall back down. **Phase 3** warps the player is warped to the very bottom. They're confronted with several Gunnoid-M02s which can easily be taken down before a climb to the top and the last attack against Big Boy.

## Appearance

Big Boy is a cycloptic machine shaped like a nuclear missile. His body is black with light grey spikes and dark plates with 3 screws in them. At the bottom is are dark grey drill-like grooves with a white orb at the bottom that fires Nega Rainbow Beams. His eye has a white sclerae with a grey square iris with an inner black iris; his eyelid is black with the Mechanto emblem on the upper half.

## Personality

Big Boy appears to be a reasonable individual who seems bored due to the constant victories against previous Gunnoids. He also seems interesting in knowing if Gunnoid-0 is really as skilled as he's heard or it was just an error in judgement. After being defeated, he takes his loss well and tells his opponent that he looks forward to serving them in the future. Much like the other boss machines, he is loyal to his master and intends to prove to them that Gunnoid-0's existance is justified.

## Story

### Gun

Regardless of which order the player goes, they'll encounter Big Boy. If the player defeated War Machine or the Diamond Dogs first, he'll remark that news travels fast and wishes to see if their skill is genuine or an error of judgement. If Big Boy is the first boss the player fights, he'll reveal that you're another Gunnoid born and another to be destroyed. Either way, Gunnoid-0 partakes in a 3 phase battle against Big Boy.

After Phase 1 ends, Big Boy warps Gunnoid-0 to the second floor and tells them to ascend in order to prove to his master that their struggle was worth it. Once Phase 2 ends, he warps them to the bottom which resembles a scrapyard. It's then revealed that Gunnoid-0 is to become leader of the Gunnoid-M02s assuming Big Boy doesn't add them to the scrapyard.
After a climb back to the top, Gunnoid-0 defeats Big Boy. He then proclaims that with Gunnoid-0 on his side, they'll win. Gunnoid-0 is then warped to the Boss Data Server and obtains the Big Boy's N.R.B (Nega Rainbow Blaster). After this, the player is free to return to Purpose and refight Big Boy.

## Trivia

* All 3 phases of the fight use Heavy Press's A.I, and Cibryll helped King (2.0) script the fight.
* Big Boy is the only boss in the main story whose boss title stays the same in all phases. The Taboo don't count because all 3 are separate bosses sharing the same title.
* Big Boy's boss fight went through several changes throughout development: originally, the boss fight would've taken place on a single floor and would have lava rising for the second and third phases. Later on, when the fight changed to have multiple floors, Phase 3 was originally going to have rising lava but King (2.0) was unable to implement it and it was dropped.
* The fight with Big Boy was created as a test of taking the same Cave Story boss and giving them multiple phases.
* Big Boy (the main antagonist of Gun v3)'s name is derived from the lyrics of 10CC's I'm Not In Live, particularly the lyric: "**Big Boy**s don't cry".
