Suicide Squad Isekai

Harley Quinn is captured after another crime spree with the Joker and taken to Belle Reve, where Amanda Waller adds her to a new task force. Deadshot, Peacemaker, Clayface, and King Shark are placed under the same command, with Rick Flag sent to keep them moving. Explosives in their bodies give them a short deadline and no real choice. Waller sends them through a gate into a kingdom cut off from Gotham, where magic, monsters, and armies have made the political situation unstable. The group is arrested almost as soon as they arrive, then forced into service after proving that their methods can shift battles faster than local commanders expect. Harley treats the mission like another chance to cause trouble, while the others look for ways to survive long enough to return home.

The kingdom’s war is already tangled before the squad enters it. Princess Fione wants to protect her people, Queen Aldora hides what she is using the conflict for, and hostile forces include enemies who were sent through the gate before Waller’s team. Katana, Ratcatcher, Thinker, Enchantress, and Killer Croc appear as threats tied to the other side, turning the mission into a fight against people who understand both worlds. The squad wins ground through ambushes, betrayals, and reckless improvisation rather than discipline. Rick Flag tries to keep the objective clear, but each battle exposes that Waller’s plan is incomplete and that the kingdom has its own secrets. Harley pushes Fione to act for herself, while the squad learns that finishing the mission means breaking more than one chain of command. By the end, they have disrupted the war, exposed the force controlling the throne, and earned a way back without ever becoming the obedient tools Waller wanted.
