One Piece Season 20 Episode 137: The Straw Hats Sail Straight into Trouble

The Supernovas Strike Back! The Mission to Tear Apart the Emperors! understands that a One Piece adventure becomes memorable when spectacle and character choice arrive in the same moment. First released on 24 July 2022, it places Kaido and Big Mom within the Wano Country arc and explores battle. The premise is clear, but its impact comes from the reactions, promises and difficult choices surrounding it.

⁠

The setup connects Kaido and Big Mom with akazaya, take and orochi, then lets competing priorities create the pressure. It is a flexible structure, moving between private emotion and wider danger without losing direction. The escalation works because every new obstacle asks a more difficult version of the same question. What seemed simple at first gradually exposes the values that the characters are unwilling to trade away.

⁠

The episode understands that Kaido is most compelling when strength and need appear in the same scene. Big Mom supplies resistance without becoming a convenient obstacle. Their interaction has texture, and the supporting players add pressure without stealing the centre. This is character drama built from competing loyalties, which gives the action a reason to matter beyond who lands the final blow.

⁠

There is a satisfying physical rhythm to the episode. Moments of stillness gather pressure before motion releases it, and the larger images are anchored by expressive faces. The world of Wano Country contributes more than scenery because its spaces influence strategy and mood. Even when the animation reaches for impossible scale, the scene remains connected to the immediate fear or promise driving the characters.

⁠

The wider world building remains carefully connected to the present conflict. Information about Wano Country Saga is valuable because it changes how a character understands the next decision, not simply because it expands a reference guide. That distinction keeps the mythology alive. The seas feel enormous, yet the episode provides one clear emotional doorway into them, allowing history and politics to deepen the drama rather than pause it.

⁠

What holds the episode together is its attention to strength, strategy and the difference between winning a fight and earning a victory. The subject appears through grand gestures, but smaller reactions prevent it from becoming empty melodrama. A weaker version might deliver a neat answer. This one allows uncertainty to remain, which suits a voyage shaped by incomplete history and impossible dreams. Progress matters because it is chosen without any guarantee of comfort.

⁠

The chief reservation is that the escalation briefly becomes broader than the emotional setup can comfortably carry. A couple of beats repeat the same point, and the final shift is tidier than the preceding conflict suggests. Yet the episode recovers whenever it returns to a direct exchange between the central characters. Those scenes preserve the honesty that the busier material sometimes threatens to bury.

⁠

The Supernovas Strike Back! The Mission to Tear Apart the Emperors! earns its place in the voyage through character rather than novelty alone. The premise is memorable, but the reactions give it shape and feeling. I appreciated the willingness to let Kaido and Big Mom be brave, uncertain and occasionally unreasonable at once. That complexity, delivered with adventurous confidence, makes the episode worth returning to after its immediate question has been answered.
