The destruction caused by Trebol was enough to bring the attempted attack on Sugar to a stop as the dwarves were rounded up and interrogated. The dwarves however were betrayed by their naivety and revealed Usoland to them, allowing Trebol to ignite the slime they were caught in. Leo survives and lands near Usopp and Robin who evaded capture. Leo weakly told Usopp that their plan must succeed for the sake of their captain.
At the Palace, Thunder Soldier was brutally kicked out of the lift by Lao G, and has a flashback of his fight with Rebecca over the false news of Doflamingo's resignation. At the Colosseum , Rebecca lies beaten by Diamante who taunts her over the death of her mother. Seeing this, Sabo told Bartolomeo to protect Rebecca. Thunder Soldier was later saved by his dwarf squad from Lao G, and the survivors told him that he must press on.
Usopp was skeptical that they would put all their faith on a simple toy soldier, but Leo reveals that Thunder Soldier was the first to be turned into a toy and not given a contract. It is why he leads the resistance and that his human identity was the legendary gladiator, Kyros.
