The Kraken
Reggie was explaining to Captain Lockman about how they failed to get the Kraken to get some of its blood. He then reveals Olaff Hargover is in hostage by a group of villains. Soon, at Norway, Lockman lets Steppenwolf go and keeps Meg hostage. After Meg knocks him out with a pile of dead fish, she goes to the other side of the ship and goes into Olaff's workshop and sees a submarine with a curtain. After removing the curtain from the sub, it is revealed that a bomb is on the sub. After putting the bomb on a speed boat and exploding at a far distance, a girl named Oola enters the workshop. She said that her father is in hostage by a group of villains now known as the Dagger League. Meanwhile, we see a man driving Steppenwolf to Olaff's house. The man drops Steppenwolf next to the house. As Steppenwolf enters the house, the house is wrecked and Olaff is seen tied up on the sofa with his left leg missing. He told Steppenwolf to look out. But it was too late. A member of the Dagger League has knocked out Steppenwolf out and tied him up on a chair. Fortunately, a dagger was near Steppenwolf and he grabs it with his legs and he unties himself and unties Olaff. There were about three of four Dagger League members. Olaff told Steppenwolf to get him artificial leg so they can all escape. After he crushes the first Dagger League member with a shelve with books, Steppenwolf finds Olaff's artificial leg upstairs on the bed and as he swings on a chandelier and gets back and he fixes Olaff's left leg by using the mechanical leg and he has a new leg. After Steppenwolf has killed the second Dagger League member, he and Olaff escape from the house. They then see a skylift that will take them to the other side for safety, but the path is broken. However, Steppenwolf jumps over the holes and he uses a big mallet and smashes the outside wall of the building where a piece of the wall falls and covers one of the holes and this makes Olaff safely cross over. As they cross over, two Dagger League members tried to kill them by breaking the wires for the lifter to fall. However, Steppenwolf has managed to get the lifter to safety. They head to the oil works and as they enter the workshop, they find Meg and Oola. Oola told her father to put down his project hold for a while, because she said it is becoming far too dangerous. Olaff said to his daughter that the project is exactly what the Dagger League want. But the Dagger League don't realize that Olaff has a got a bone to stick with the "creature from hell".
Soon, Olaff, Steppenwolf, and Meg are at an oil works fixing the submarine now known as Deep Blue. As Meg watches them leave in Deep Blue, the Dagger League as came and attack her. After the Dagger League members were defeated (one accidentally slips on oil and falls to his death in the ocean, one is hit by the big hook while getting distracted by the smoke coming out of the wrecked pipe, one is locked inside the building when Meg threw a wrench inside the working area and the member followed the noise, and the other one was crushed to death by the barrels of oil). Meg then went after the leader. As she knocked out the leader with a rag with chloroform, she removes the mask, revealing to be Oola. She ties up Oola and asked why was she being with the Dagger League. Oola said the Kraken is a "secret that won't be revealed" and Oola also said that she and the Dagger League took care of Deep Blue and it is "too late" for Steppenwolf. Oola said that Steppenwolf will go very deep into the ocean and will "stay" there. Suddenly, a helicopter arrives and reveals the Captain Lockman has arrived. Meanwhile, under the deep ocean in the submarine carrier, Olaff told Steppenwolf to be careful with the submarine, because he spent years building the damn thing. As Steppenwolf gets into the submarine, the propulsion mechanism is broken, but Olaff told him that it should be working, because he tested it three days ago. Steppenwolf then finds the Kraken's tentacle. He scares it away by using a flagpole that broke the giant sharp rocks. Steppenwolf then scares it away when the submarine landed on the crumbled platform, which was destroyed and landed on a big part of a sunken ship which scared the Kraken away. Steppenwolf then uses a mine and attaches it on a grid and when the Kraken touched the mine, the mine exploded and scared the beast away. Steppenwolf then uses a torpedo bomb and drops it in the trench which touches a lava tube which exploded and the lava tube shot out lava which scared away the Kraken in its home. Steppenwolf uses a net and captures three angler fish and they light up the inside of the Kraken's home, revealing the monster. He also blocks the hole with the net to prevent the angler fish from escaping. Steppenwolf uses a winch and attaches it on a small stalagtite. He was ready to battle the Kraken, but the electric stunners were empty. Steppenwolf finds a cannon and takes it. He goes back above the trench and finds a small sunken ship and bashes it with the cannon and finds a lot of working electric charges. He brings the electric charges and heads back down to the Kraken's home. The submarine grabs the winch and he swings and throws three charges in the Kraken's mouth, stunning it. Steppenwolf then uses the syringe and collects some of its blood (however, the longer Steppenwolf waits, the Kraken will recover). As Steppenwolf leaves the trench, he uses lifeboat and floats up into the submarine carrier. Olaff and Steppenwolf get out of the sea and head back to the oil works and find Meg sitting next to Captain Lockman and Oola. Olaff was shocked of his daughter being the leader of the Dagger League. Lockman then told everyone to stop the meeting. Steppenwolf then shows Lockman the Kraken's blood and he said that he could get the job faster without Lockman. Lockman said it doesn't matter and said that Reggie Donovan is waiting for their "little treasure".
