Emotion Window

The Emotion Window is a mechanic introduced to the MegaMan Battle Network series, starting from MegaMan Battle Network 4. Depending on how the player performs during virus or Navi battles, the Emotion Window can change to reflect MegaMan's current mood, and this will affect the player's performance as long as the changes are in effect. If MegaMan is inflicted with a bug from the Navi Customizer or other sources, the Emotion Window will flicker to reflect this.

Full Synchro

 * Main article: Full Synchro

Full Synchro is obtained when the player manages to perform a counter hit using a non-dimming chip attack. MegaMan glows bright blue and a pink spinning ring surrounds him. In this state, the player's next chip attack has double power, and attacking enemies will flash during the timings when they can be countered, encouraging the player to remain in Full Synchro.

Full Synchro expires when the player is hit by an enemy attack, or when the player performs a chip attack. It cannot be accessed when MegaMan is using a Double Soul or Cross, but can be used while he is in Beast Out. Full Synchro can also be initiated while the player is controlling another Navi.

Anxious
MegaMan turns Anxious when he takes multiple hits without successfully retaliating. While Anxious, MegaMan is unable to perform Double Soul. In Battle Network 4, Dark Chips also become available for MegaMan to use, and if MegaMan has used enough Dark Chips, he can start the battle in Anxious state, with the Dark Chips already available for use. The Anxious state is unavailable in Battle Network 6.

Dark Soul
Dark Soul is obtained when the player has used a Dark Chip. MegaMan turns dark, gains access to the DS Navi chips and other Battle Chips exclusive to Dark Soul MegaMan, but is unable to use SP Navi chips and other chips such as Sanctuary. If MegaMan would be deleted, he remains at 1 HP and turns completely black, becoming invincible but uncontrollable for several seconds. He then moves and attacks randomly with Buster shots, loaded chips, or any chips and Program Advances which the player has previously used.

If MegaMan has used enough Dark Chips, he can start the battle in Dark Soul state, with Dark Chips already available for use in Battle Network 4. Dark Soul is unavailable in Battle Network 6.

Rage
If MegaMan takes over 300 damage in one hit, or just broke free from a status effect without any effort in reducing its duration, he enters a Rage state. Here, he gains Super Armor, meaning his attacks cannot be interrupted, and his next chip attack has doubled strength. Unlike Full Synchro, Rage does not expire when MegaMan gets hit, but instead dissipates over time, or once he uses a chip attack.

Pinch
Available only in Battle Network 5 DS, the Pinch state triggers if the player performs poorly in battle, like taking a large amount of damage and falling to low HP. The player can then blow into the microphone to give the current Navi a few buffs, ranging from a 100HP Barrier to instant Full Synchro to a restoration of 300 HP. This state can be obtained while controlling any Navi.

Tired
Replacing the Anxious state in Battle Network 6, the Tired state is obtained once MegaMan's emotion counter reaches 0 due to use of Beast Out. Much like the Anxious state, MegaMan cannot enter Full Synchro. If MegaMan attempts to initiate Beast Out a second time during battle, he instead enters Beast Over, where he goes completely berserk for a turn.

Double Soul, Cross, Beast Out
When MegaMan enters any of the above transformations, his Emotion Window changes accordingly. While the transformation is in effect, MegaMan cannot enter any other emotional state, except for Beast Out, which is capable of using Full Synchro. Crosses also have their own sprites if they are used while MegaMan is Tired.

Double Souls and Beast Out use a timer on the right edge of the Emotion Window. Once said timer reaches zero, the transformation expires.

Exhausted
If MegaMan has yet to finish off the opponent after entering Beast Over in Battle Network 6, he enters the Exhausted state. MegaMan suffers from a severe HP glitch, his Buster stats are all reduced to 1, and he cannot initiate any transformations.
