'''First Season'''

* The first episode when the battle Drago and a Fear Ripper driven crazy by negative energy went all the way into Dan and Shuji's battle and their partnership began.
* Two for episode 2, first goes to Masquerade fro making the #1 spot in like a day, and second to Drago when his power level is so high it destroys the field.
* Dan beating Ryo in their rematch after he and Drago make up by [[BeatThemAtTheirOwnGame out-strategizing Ryo.]]
* Runo winning her battle in episode 5, because not only was it a great debut for Tigerra but she did it while still having two Bakugan in a Doom Card battle.
* Preyas's debut in episode 7 where he showed off his attribute changing powers.
* Julie beating Billy was in the Top 20 at the time after getting Gorem in episode 9.
* Episode 11 shows Shun and Skyress beating both Runo and Marucho and Tigerra and Preyas showing why they used to be #1.
* Episode 20 has Shun defeating Komba in a CurbStompBattle, without losing any of his Bakugan to the Doom Dimension.
* Episode 30, wherein Marucho battles Frosch and Preyas evolves, summoning Angelo/Diablo.
* The final brawl between Masquerade and Dan, with Alpha Hydranoid and Ultimate Dragonoid slugging it out. They stalemate ''three times'' before Drago narrowly wins, actually causing ''[[TheStoic Masquerade]]'' to finally flip his shit and vent his built-up frustration . They had the duel in an epic Stadium as well.
** For that matter, Masquerade helping Dan defeat some of Naga's minions before fading away.
* The season finale, with the six new guardian Bakugan (the brawlers) squaring off against Silent Naga.

'''Second Season'''
* Maxus Dragonoid vs Maxus Helios.
** When the system forcing Bakugan to take on sphere form on Vestroia is destroyed, their battle is prematurely terminated. That doesn't stop Drago and Helios from kicking the DuelsDecideEverything trope to the curb and slugging it out the old-fashioned way.
* Lync threatens Dr. Michael. How does Alice respond? She backhands him in the face.
* When Alice is being pursued by Shadow, she is rescued by Chan Lee. Not through a brawl; Chan Lee kicks him straight in the stomach.

'''Third Season'''
* Aranaut gets one during a flashback in episode 26. Kazarina has him strapped down to a lab table and is torturing him after she'd already [[spoiler: killed his partner Jin]]. So what does the normally reserved and composed Aranaut do? He threatens to ''kill'' Kazarina for what she's done.
--> '''Aranaut''': Curse you! You will pay for what you did to [[spoiler: Jin]]! I'll rip you to shreds!
* In episode 35, Jake breaking free of Kazarina's [[MindControl hypnosis]] and slamming into her like a football player just as she was about to kill Dan.
* Kazarina and Nurzak's sword duel (well, blade tipped staff in Nurzak's case) in episode 37, despite how brief it was.

'''Fourth Season'''
* In episode 9, when Dan and Drago getting Zenthon under control for the first time. Zenthon then helps Drago by defeating Venexus and Anubias, causing him to flee.
* Episode 14, when Drago manages to completely tame Zenthon for the first time.
* Episode 23, the summoning of Zenthon.
--> '''Zenthon''': I have been summoned by my masters to stop you and crush you where you stand, you filthy insect.
* This is pretty much a Crowning ''Season'' Of Awesome, as they fixed pretty much ''everything'' the fans were complaining about.
* During ''Blast from the Past'', an arrmy containing many of the previous seasons' Bakugan takes a stand against Mechtavius destroyer, with many of them having a DyingMomentOfAwesome. Special mentoin goes to Shun's previous Ventus guardians (Skyress, Taylean, Ingram), Preyas, and Alpha Hydranoid, who inconvenience Mechtavius and survive against him for an extended period of time, respectively. ''The'' MVP of the episode, however, is Blade Tigrerra, the last one of the army still standing. Now, Tigrerra was one of the main Bakugan in the ''first season'', and even then she honestly was playing third fiddle to Drago, Hydranoid, and Skyress. Mechtavius Destroyer, on the other hand, is the absolute final BigBad in a show where the SortingAlgorithmOfEvil is in full effect. So normally this would obviously be a CurbStompBattle, right? Nope, she [[DoNotGoGentle makes a defiant final stand]], deflects several of his attacks, and actually makes him keel over in pain. What a way to go.
* The final battle with Mechtavius Destroyer. How do they finally stop this killing machine? Drago evolves again? Nope, not this time. [[spoiler:Dragonoid Destroyer calls upon every Bakugan on Earth with a human partner to lend him their power, causing him to enter a GoldenSuperMode with ''infinite attack power''. He then channels this [[CombinedEnergyAttack energy into a beam]] that ''vaporizes'' Mectavius Destroyer. To add to this, Genesis Dragonoid, the original Bakugan and Drago's ancestor, speaks through Dragonoid Destroyer to give Mechatvius Destroyer a TheReasonYouSuckSpeech. Not only was it awesome, ''the entire world'' defeated Mechtavius Destroyer, not just Dan and Drago.]]
