Double Soul (MMBN5)

Double Soul (ソウルユニゾン Soul Unison) is the main transformation system of Mega Man Battle Network 5, it can only be used by Good MegaMan.

How to Use

To Double Soul, the player must sacrifice the respective element chip to unite with MegaMan (the chip cannot be a Regular Chip). The transformation will last 3 turns or until it is overwritten by another Soul. However, the Navi Customizer part SoulTime+ and some Patch Cards have the ability to increase or decrease the number of turns.

• Each Soul can only be used once per battle.
• If MegaMan attempts to use a DarkChip while Double Soul, he will first lose the Double Soul form before executing the chip.

Changes from Battle Network 4

• The Souls' B Button PowerAttack value are now dependent on MegaMan's buster stats.
• MegaMan's B+Left ability can only be used in his Normal form. When in a Soul, it is disabled (or replaced if the Soul has one).
• The A PowerAttack for x2 chip attack has been changed to double the base attack power before any plus chips, instead of the attack power sum.
• If a "Unite" eligible chip is selected; when the cursor is on the bottom row of the Custom Screen, press left while on the leftmost chip or right on the rightmost chip, then it will slide the cursor to the "Unite" button. In BN4, doing this will still take the cursor to "OK".
• The Unison takes place before the BATTLE START text instead of after.
• Losing the Double Soul is now during a dim before the BATTLE START instead of when the player regains control of MegaMan after it expires.
• Search Soul now unites with Cursor element chips instead of Invisible element.
  • Search Soul now allows the player to see how many chips an enemy is holding in Network Duels.
• Proto Soul no longer removes flashing from Sword chips. Sword chips now retain their flashing properties.
  • Proto Soul now steps forward with a charged Z Saver.

Chaos Unison

Battle Network 5 introduces an extension of Double Soul in Chaos Unison (カオスユニゾン). To Chaos Unison, the player must sacrifice the respective DarkChip to unite with MegaMan. The transformation will only last 1 turn and cannot be extended. Chaos Unison counts as a different form than their Double Soul counterpart, so they can be used with their counterpart in the same battle.

They share the same abilities as the normal Souls except their B Button PowerAttacks become Dark Chips. The fully charged attack will alternate between green and purple.

• If released at purple, the Dark Chip will be used. Each successful use of the Dark Chip power will make the charge time take longer.
  • If the button is released during pausing, it will use the charge when it was paused.
• If released at green, MegaMan loses his form and Dark Soul spawns on the enemy side using your most used chips during your playtime. The Dark Soul cannot be hit and will disappear after some time.

The negatives of the Dark Chips are also nullified, so MegaMan won’t be affected by bugs. However, if the attack damages the enemy they’ll receive a weaker variation of the bug you would’ve received.
