For these reasons, it’s ultimately hard to predict the outcome. After all, fluctuating power levels and new transformations are a constant part of the “Dragon Ball” universe, and the underdog does occasionally come out on top in certain fights by finding a hidden drive with themselves or an emotional epiphany that signifies a new change to their self-understanding.
With this in mind, it is possible that Jiren could still beat Beerus, but it is still ultimately unlikely. This is because Jiren is an incredibly stoic character by his very nature. Though he did have an outburst of emotion when he was defeated by Goku, for instance, it wasn’t enough to change his abilities in any substantial manner during this part of the conflict. Since most transformations in the “Dragon Ball” franchise seem to hinge on some kind of emotional revelation or event, this seems like it could also be a detriment for Jiren reaching a higher form. Still, since we have yet to see Beerus or Jiren at full power, there is some wiggle room here.
For this reason, it seems that as far as power rankings currently go in “Dragon Ball Super,” Whis (Masakazu Morita/Ian Sinclair) is at the top, with Beerus likely next in line. All the same, with even less pivotal characters, like Piccolo (Takeshi Aono/Christopher Sabat), evolving into new forms after all of these years, the ranking may not stay that way forever.
