Back under the surface, Rastapopoulos was still questioning Haddock if he was willing to relinquish his power in order to get Tintin back. Even though Haddock was not following with the contract's orders, he still did want Tintin to come back home.

"Now, have we got a deal?" Rastapopoulos sneered. Sighing with hesitation, Haddock gave in. "I will relinquish my power…and you give me back the boy," he said. Raising his trident, Haddock then signed the contract. "The deed is done," Rastapopoulos said. He then thrust Tintin forward, who in turn embraced Haddock. Suddenly, without warning, Rastapopoulos sent a bolt of lightning toward Haddock, causing him to wither away into a worthless soul.

From afar, Yan and Chang watched in unspeakable horror. "No! Please, no!" Tintin cried out. Yan could do nothing but stare listlessly into the eyes of the once beloved king. "Oh, Your Majesty…" she muttered. "Haddock?" Tintin whispered. "I'm sorry…"

The friends did not happen to notice Rastapopoulos grabbing the crown. "At last," he muttered as he was about to place the crown on his head. "The power is mine…" "You…you beast!" Tintin shouted angrily, pushing the crown off Rastapopoulos's hand.

"Now don't fool with me, you worthless, little brat!" Rastapopoulos thundered. He forcefully grabbed Tintin's arm and was ready to strike. "Contract or no contract, you still belong to…Aaaaaahhhhh!"

Before he could berate Tintin, a harpoon came out of nowhere and struck Rastapopoulos's arm. Tintin looked up and gasped. It was Alex! "Why, you sly witch!" Rastapopoulos exclaimed. Alex then tried to swim for her weapon and grab it. "Alex, be careful!" Tintin exclaimed.

"After her!" Rastapopoulos ordered. Tom and Allan then began catching up to Alex, ready to attack. "Come on, let's get out of here!" Yan cried out as she and Chang fled. Igniting the trident, Rastapopoulos aimed it straight toward Alex. "Say goodbye, fair maiden!" he said.

But in the nick of time, Tintin pushed Rastapopoulos, causing him to send a bolt of lightning toward Tom and Allan instead! The two eels were then caught in a twisted knot. "My minions!" Rastapopoulos cried out. "No, no!" Tintin then grabbed Alex and swam up to the surface as Rastapopoulos began to grow in size.

Tintin then got Alex back up to the surface just in time. The sky was beginning to grow dark as night gave way. "Alex, leave now," Tintin said. "You have to get out of here while you still can." "No, I won't go without you," Alex said. "You have to! It's the only way!" Tintin said.

"YOU PITIFUL, INSIGNIFICANT FOOLS!"

Suddenly, Alex and Tintin were lifted from the ocean as a now giant and massive Rastapopoulos towered over the sea. Now that Rastapopoulos assumed total power, he was more powerful than ever. Grabbing tightly onto Tintin's hand, Alex tried not to let go. But, from underneath them, the surface rumbled and shook, making it seem unsteady. "Look out!" Alex cried out, but suddenly, her hand slipped, causing Tintin to fall back into the sea.

"NOW I AM THE MOST POWERFUL RULER OF ALL THE OCEAN!" Rastapopoulos thundered. "THE WAVES NOW OBEY MY EVERY WHIM! AND THE SEA AND ALL OF ITS SPOILS SHALL BOW DOWN TO MY POWER!"

With a wave of the trident, Rastapopoulos began to raise shipwrecks from under the surface and cause chaos all around. But he was not through with his victims yet. As thunder and lightning crashed everywhere, Rastapopoulos decided that he still had one other pest to deal with. He then summoned a giant whirlpool…and then he began pulling Tintin straight toward it!

"ALEX!" Tintin shouted as he was being sucked further into the whirlpool by the strong currents. Alex, with a sense of despair, then swam up to the nearest ship she could find. Climbing on, she tried to steer the ship toward Rastapopoulos. Rastapopoulos knew that the whirlpool was getting nowhere into getting rid of Tintin. It was then that he decided that the only way was to kill Tintin. Raising the trident high, he sent waves of lightning toward the boy. But Tintin was quick enough to avoid them.

"HA, SO MUCH FOR YOUR ONE TRUE LOVE!" Rastapopoulos exploded. As the trident began to glow a deep red, he aimed it toward Tintin! "NOW, TO FINISH YOU OFF!" he thundered. "SAY GOODBYE, YOU WORTHLESS, PITIFUL SOUL!"

And just as he was about to strike, Alex was quick to steer the ship straight toward Rastapopoulos. As she did, she rammed the ship's broken mast right into his body! After getting impaled by the broken mast, Rastapopoulos uttered a horrifying cry of pain and sank to the bottom of the ocean, thus meeting his untimely demise. A massive wave was sent forward and sent Alex's ship toward the beach, crashing onto the shore.

Down below, the trident fell toward the withered creature in front of Yan and Chang. Suddenly, the trident glowed, and Haddock transformed back to his old self. Yan and Chang cheered as they embraced their king.
