# Mega Man Battle Network/Soul Unison Guide

This guide will cover the basics of DoubleSoul and Chaos Unison (here, collectively referred to as Soul Unisons), introduced in Battle Network 4 and Battle Network 5, respectively.

## How to use

Firstly, Soul Unisons must be performed while MegaMan is in either normal, angry, or full-synchro emotions (curiously, this also means you are unable to use Chaos Unisons in dark mode). To perform a Soul Unison, select an appropriate chip and use the "Unite" option. The unison cannot be undone by pressing B. The chip sacrificed cannot be used for the remainder of the battle. Note that Soul Unison is effectively a chip that you send to MegaMan with no particular coding, so you can send four more chips to MegaMan, as normal. Before the battle resumes, the Soul Unison is performed, and the Emotion Window changes to show DoubleSoul MegaMan. Chaos Unisons require the sacrifice of a DarkChip, but are otherwise performed the same as regular DoubleSouls.
While in Soul Unison you will not gain some benefits from the Navi Customizer (most notably, Shield and Reflect cease to work until you lose the unison). You can only unite with a soul once in battle (ie. you can use Soul Unisons up to six times, one for each soul in the game), and you cannot sacrifice your regular chip for Soul Unisons. You also cannot go into Full Synchro while a Soul Unision is in effect. DoubleSoul lasts for three turns (but can be reduced or extended in Battle Network 5 with the use of the SoulTime+1 Navi Customizer part and various e-Cards), while Chaos Unisons last for only one turn and cannot be extended.
While in Soul Unison you will gain particular benefits, including a change in charged shot, BattleChip bonuses, and the like. Chaos Unisons replace the normal DoubleSoul's charged shot with the DarkChip sacrificed (but without the negative effects of the DarkChip, although you get the DarkChip glitch whenever you lose the Chaos Unison). However, the charged shot must be released when the charge is purple in color, or an indestructible Dark MegaMan will appear and generally wreak havoc on you (on top of losing your Chaos Unison). Having said that, some say that this is the only real use for DarkChips.
Here's a list of Soul Unisons that you can perform.
| Chip type | MegaMan Battle Network 4 | MegaMan Battle Network 4 | MegaMan Battle Network 5 | MegaMan Battle Network 5 |
| Chip type | Red Sun | Blue Moon | Team Colonel | Team ProtoMan |
| Fire | FireSoul | | | NapalmSoul |
| Water | | AquaSoul | ToadSoul | |
| Electric | ThunderSoul | | | MagnetSoul |
| Wood | | WoodSoul | TomahawkSoul | |
| Sword | | ProtoSoul | | ProtoSoul |
| Wind | WindSoul | | | GyroSoul |
| Cracking | GutsSoul | | | |
| Breaking | | MetalSoul | KnightSoul | |
| Aiming | | | | SearchSoul |
| Invisibility | SearchSoul | | ShadowSoul | |
| Summonings | | JunkSoul | ColonelSoul | |
| Recovery | RollSoul | | | MeddySoul |
| Plus/Minus | | NumberSoul | NumberSoul | |

## Unisons and DarkChips

DoubleSoul improves your karma, while DarkChips lower them (thus, Chaos Unisons do not alter them). In Battle Network 5, if you use a DarkChip while in Soul Unison, you will be immediately brought out of Soul Unison, and you will suffer from the effects of your DarkChip. Curiously, you are unable to even Chaos Unison while in dark mode.
