WhenDragon Ball Z: Kakarotplayers finish off Kid Buu, there’s a good chance that most of what the player wants to do in the game is done. Completionists, though, may try to unlock all ofDragon Ball Z: Kakarot’s trophies or achievements, and for that, they are going to need to unlock and take on the secret boss fight.
While unlocking this boss fight cannot be done until the end ofDragon Ball Z: Kakarot, players can work on it over the course of the game. It’s a pretty direct method, but even for those who don’t care for achievements, it’s worth mentioning that this secret boss fight has some serious implications for DBZ canon that diehard fans will want to see.NOTE: MOVING FORWARD, THERE ARE MASSIVE SPOILERS FOR DRAGON BALL Z: KAKAROT

That secret boss fight is none other than Mira, with him and Towa appearing inDragon Ball Z: Kakarot. To unlock the boss fight, players will need to defeat every villanous party that appears in game, which ends with a fight against evilSuper Vegito and evil Super Saiyan 3 Gotenksprior to taking on Mira (who is level 100). While this may sound daunting for the fresh-out-of-the-Buu Saga character, beating Mira and the aforementioned villainous parties isn’t as difficult as it initially may seem. With the proper items and know-how, winning is as simple as having a few healing items available.

Either way, Mira is a 5 million HP sponge that players just need to wittle down, but the fight isn’t the interesting aspect of this character: it’s how he and Towa influence canon. After beating a few villainous parties, players will see a cutscene where Towa is seemingly powering up Mira’s core and speaks of his revival. Towa then later comments on his revival, saying that defeating the player will make Mira the ultimate warrior. Goku, or whicheverDragon Ball Z: Kakarotplayable characterthe player chooses, refrains from commenting on anything throughout all of this.
After Mira is then beaten, Towa says they’ll travel to another timeline in order to get Mira the necessary power. This is where it gets interesting. In the events of the firstXenoverse, Demigra, Mira, and Towa are defeated, with Towa escaping with Mira’s core and promising to get him the power he needs. In the events of theXenoverse 2, Mira returns powered up without explanation, just having recovered from his near-death experience. And that’s whereDragon Ball Z: Kakarotcomes into play.
This secret boss fight explains just that: how Mira recovered by the events of the second game. In other words,Dragon Ball Z: Kakarotand theXenoverseseries are connected in ways players would not initially expect, and this means that it’s likely “canon” now. Of course, there’s always been a debate over how video games and TV shows cross over and whether or not canon is involved, butDragon Ball Z: Kakarotis billed as the most accurate telling of the show to date. It changes a few things, such as the moment wherePiccolo destroys the moon, but at its core, it doesn’t truly contradict canon.
In this manner,Dragon Ball Z: Kakarotbrings together the anime,Xenoverse, and evenDragon Ball FighterZ’s Android 21in a way that could be considered canonical. After all, the Cell Saga has already established that there are multiple timelines, so this ending means there’s theXenoversetimeline, the various timelines involved in the Cell Saga, and perhaps a timeline for Android 21 (though, at this time, she’s not really shown to do much in this timeline).
Perhaps this will be elaborated upon in the future, or perhaps it’ll be left to player interpretation. However, it’s clear thatDragon Ball Z: KakarotandDragon Ball Xenoverseare intrinsically connected, just as different timelines, which is a really neat way to reconcile every detail concerning the sheer number ofDragon Ball Zgames.
