Heroic Benchmarks with Heating-up Periods

Heroic Benchmarks who may act a little differently than they normally would.

Examples include:

1. A hero who fell into despair and lose their hope because of losing their loved ones, being betrayed, being defeated or failed, having personal issues or they were being looked down by others. Usually, the hero would become hostile and refused to do anything optimistic as they would rather give up instead of standing up who they are. Sometimes, the hero would break into tears and lamenting on their problems. Under these circumstances, the hero would prefer to be alone and stay away from others. After the moments, the hero would come to get over their depression and go back to helping others (e.g. Momo). In these circumstances, the hero also temporarily lose control and seek revenge. However, they managed to regain their sanity and mercifully spared others' lives for good. Some heroes can be nihilistic in some cases.
2. The hero becomes hostile and has moments of being jerk to others. This may be because they are insecure, being persuaded by others with bad influence, being annoyed, unintentionally doing it so, or going through a phase in their character. In these moments, the hero would break out of this mentality and apologize to those whom they offended. In other moments, the heroes would learn from their behavior and not to repeat it (e.g. Ennui and Stuart).
3. The hero would lose their temper and get angry with others, mostly for good reasons. It is mainly because of something that irritates them, anyone making mistakes, getting into arguments, being deceived, or their loved ones being harmed. However, the hero managed to calm down instantly and apologized for their behavior. Sometimes, the hero would never apologize, if it's well-reasoned (e.g. Princess Daisy, Anastasia Romanov, King Rhoam, Maisie Lockwood, Skylor Chen and Marina).
4. The hero would make mistakes which unintentionally caused problems with others. The reasons for this include mischief, carelessness, and somewhat doing reckless things without consent. Despite this, the hero would fix their mistakes and not to repeat it again (Hestu).
5. The hero was exposed to toxins or forces that brought out their darkest qualities or something even worse. The heroes under these instances were either possessed, corrupted or brainwashed from an external source. However, the heroes managed to recover themselves (e.g. Rogue Cheney, Lady Olivia, and Viper).
6. The hero could temporarily ally with villains for their good intentions, on undercover, pragmatic reasons, or being manipulated by them for their own gains. However, the heroes would eventually realize it and rebelled against them for this. (e.g. the Equestria Girls version of Rarity)
7. The hero can have mental breakdown or a tantrum, such as anxiety, depression, or worse, losing control of themselves. However, they managed to get over with it (e.g. Fishy Boopkins, Bowser Jr., Anxiety, Jet the Hawk, and Tsuyu Asui).
8. The hero who has moments of antagonizing others for any reasons, including for good. However, they later reformed themselves and apologized for their actions, sometimes they don't apologize even if it's well-reasoned. (eg. Yoshi and Envy)

This is an opposite of Villainous Benchmarks with Cooling-Off Periods and a brighter counterpart of On & Off heroes.

NOTE: This category is different from On & Off because they are switching sides or committing villainous deeds from time to time while Heroic Benchmarks with Heating-Up Periods have significant amount of time where they are acting differently than doing heroic moments or did nothing heroic at all.
