Based on Beerus's own statements, his hardest opponent is Monaka.
Beerus, the God of Destruction from Universe 7, has consistently promoted Monaka as the strongest fighter he has ever encountered. This declaration has been made on multiple occasions, notably when Monaka was introduced as a key member of Team Universe 7 for the Universe 6 vs. Universe 7 Tournament.
Beerus's Assessment of Monaka
Despite Monaka's seemingly unassuming appearance and true nature, Beerus goes to great lengths to maintain the illusion of Monaka's overwhelming strength. This charade is primarily used to motivate and challenge Goku and Vegeta, pushing them to strive for greater power by believing there's someone even stronger than Beerus himself.
Why Monaka?
- Strategic Motivation: Beerus intentionally portrays Monaka as an unbeatable force to drive Goku and Vegeta's training and power growth.
- Perceived Strength: From Beerus's perspective, for the sake of inspiring his Saiyan pupils, Monaka fulfills the role of the ultimate challenge.
To summarize Beerus's public-facing assessment:
Opponent | Beerus's Stated Assessment | Context | Reference |
---|---|---|---|
Monaka | "Strongest he's ever fought" | Publicly promoted to Team Universe 7 for the tournament. | [Monaka |
This narrative, though a deception orchestrated by Beerus, establishes Monaka as Beerus's hardest opponent according to Beerus's own words and actions within the Dragon Ball universe.
