Episode 676

The Thunder Soldier flashes back to his life before he was turned into a toy. At the age of 15, Kyros was arrested for the murder of two people. King Riku showed him mercy and allowed him his freedom after fighting 100 battles in the colosseum, to which Kyros agrees to. However, even after being acquitted Kyros continues to fight in the arena. After 1000 victories, Riku asked why Kyros wanted to battle so much. Ironically, Kyros sadly replies that all people will remember him as is a murderer.

Kyros' life takes a turn for the better when he meets Scarlett, who initially distrusts him but comes around when he rescues her from pirates. She even faked her death so she can spend her life with him. Eventually they had a daughter who she named Rebecca. When Doflamingo took over, Kyros attempts to rescue King Riku from Doflamingo. He cuts off his leg and lunges at Doflamingo, only for Sugar to turn him into a toy. Kyros (now Thunder Soldier) flees the palace with Riku, who does not remember him. Some day after the attack Scarlett was shot by Diamante when she went to get food for Rebecca.

Violet shook Kyros out of his flashback, when they noticed that extra soldiers are heading towards Doflamingo and with the element of surprise quickly slipping, the group prepares to attack Doflamingo.

In the Colosseum, Burgess's attacks are weakening the Colosseum's foundations, with soldiers remarking that another strong attack will cause them to break. Diamante reveals himself as the culprit who killed Rebecca's mother right in her face, leaving her vulnerable and in shock.

Franky lies defeated by the Doflamingo family and is calling for Usopp in his head to save the day. Down at the hidden harbor, all the toys are silently rooting for Usopp to succeed but he is shown to be unconscious. As a final farewell, Sugar puts the Tatababasco ball in Usopp's mouth and makes him swallow it. But this causes Usopp to wake up screaming with a horrible expression on his face that terrifies Sugar so much she fainted.

"The Operation Failed! Hero Usoland Dies!?" is the 676th episode of the One Piece anime.
