What Was Goku’s Power Level Against Broly?

Goku’s power level during the battle against Broly in Dragon Ball Super: Broly (2018) is not directly given in terms of an explicit number, like in the earlier Dragon Ball Z saga, but we can still discuss the progression of his strength and transformations during that fight.

Key Points About Goku’s Power:

1. Super Saiyan Blue (SSB):
   At the start of the fight, Goku initially faces Broly in his Super Saiyan Blue (SSB) form. SSB is a powerful transformation where Goku uses the power of Super Saiyan with godly ki. It’s significantly stronger than regular Super Saiyan or even Super Saiyan 3, but Broly, in his base form, is already shown to be a formidable opponent, pushing Goku to struggle.
2. Broly’s Strength:
   Broly’s strength is remarkable in this film because he is a wildcard—he doesn’t have the control or training that Goku or Vegeta have, but his power grows exponentially during the fight. Unlike typical Saiyans, Broly gets stronger as the battle goes on, and his power increases at an unprecedented rate, making it hard for Goku to match him with just his base SSB form.
3. Super Saiyan Blue Kaioken:
   At one point during the fight, Goku uses Super Saiyan Blue Kaioken (a technique that combines the power of Super Saiyan Blue with the boost of the Kaioken). This is a dangerous technique because it strains Goku’s body, but it allows him to briefly keep up with Broly’s increasing power. He used this during a critical moment to try to overpower Broly, though it quickly becomes unsustainable due to the damage it causes to his body.
4. Fusion (Vegito):
   Ultimately, Goku and Vegeta are forced to fuse into Vegito (using the Potara earrings), and this gives them the power to challenge Broly. However, they are still at a disadvantage because Broly’s rage continues to fuel his increasing power, pushing the fight into territory that even Vegito can’t completely dominate.
5. Final Stand and Gogeta:
   The final major moment of the fight is when Goku and Vegeta fuse into Gogeta (using the fusion dance). Gogeta’s power is incredibly high, and he is able to go toe-to-toe with Broly, who has reached an almost god-like level of power due to his rage and exponential growth. In his Super Saiyan Blue form, Gogeta delivers the finishing blow to Broly.

Goku’s Power Level:

• Super Saiyan Blue Goku was initially at a disadvantage against Broly, even though he was extremely powerful by normal standards.
• As Goku transforms into Super Saiyan Blue Kaioken, he becomes much stronger but suffers from the strain.
• By the time he becomes Gogeta, his power level is off the charts, much higher than anything Broly has faced before, though Broly’s unpredictable growth still challenges them.

In conclusion, Goku’s power level against Broly varies, but by the end of the movie, with Gogeta’s power, it can be assumed that Goku (as part of the Gogeta fusion) is vastly stronger than anything seen in earlier Dragon Ball arcs. However, Broly’s immense power—thanks to his rapid growth and raw strength—made it a truly intense and difficult battle.
