This is the last part of the story, but this will be the chapter when Elliot learns another power that the girls and Charlotte didn't have yet.

Hope you guys like it and leave reviews. Watch out too because a GaoGaiGar reference will be used!

Disclaimer: I don't own H20. But good news: the next new episode will air this December on Nick! Watch out for it!

As Cleo and Elliot dashed to Seaworld (which was closed since it was already evening), Zane saw them and he said, "Where are you two going?"

Elliot said, "To Seaworld. Our friends were kidnapped there, and we must save them."

Zane said, "Come, I'll give you a ride."

"Thanks Zane," Cleo said.

Seaworld, 12:15 am

Charlotte said, "Now you two will no longer be mermaids because both of us (the other is Dr. Denman) will have to wait until morning, when the people will see you two as mermaids. Then we'll both be rich!"

Emma said, "Oh yeah? Cleo and my brother will come to save us three. And your plans will not take effect!"

Dr. Denman said, "I bet not. This place is secured tonight so they'll never make it through!"

"I think not!"

They looked up and they saw Cleo and Elliot, atop a rock boulder. Cleo was wearing shades but Elliot doesn't. Elliot said, "You'll never win, even if you two join up!"

Dr. Denman said, "That will change. Charlotte, stop them!"

Charlotte used her recovered powers to attack them, but Elliot and Cleo jumped to avoid it, falling to the ground (however, they landed right) and Cleo used her water power to make Charlotte and Dr. Denman stuck together and Elliot freezing it. However, Charlotte got out by heating it. Elliot then morphed water to darts and heated them and striked it to the two. Charlotte said, "I can't believe you have all three powers too, Elliot. What a coincidence."

Elliot said, "I'm not like you Charlotte, who use your powers for bad. I'm using mine for good, like how my sister and her friends use it too!"

Charlotte said, "Well then, be with your sister and her friends!" she did a tidal wave to turn them to mermaids, but when it reached them, a blinding light covered it and Charlotte and Dr. Denman were struck by it.

The three of them were struck by the light and they feel a new power. Lewis then breaks out from the rope, but he can't know why it just happened on him. Fortunately, Miss Chatham arrived and told Lewis, "The fourth mermaid to use his powers for good will get an ability to fuse with mermaids to power him up too and get armor to defend himself."

Lewis said, "Why it didn't work on Charlotte then?"

Miss Chatham said, "Like I mentioned, it only works on a mermaid with good intentions and using the power he gets to good use."

Emma, Cleo and Rikki turned to mermaids and Cleo said, "What's happening to us? We didn't even touch water either."

Emma said, "I don't know, but only my brother can explain that- or not."

Rikki said, "Ok what now?"

The blinding light faded and both Dr. Denman and Charlotte saw it, and saw the girls as mermaids. Elliot didn't however change to a mermaid. Miss Chatham said, "Elliot, time to show them another power that Charlotte don't have."

Elliot said, "What? How do I show it?"

Miss Chatham went back to Lewis and Zane and said, "You two, say, 'mermaid fusion, approved!'"

Zane said, "Um what is it for?"

Miss Chatham said, "Just say it. You and Lewis."

With a confused look, they said together, ="Mermaid Fusion, Approved!"=

Elliot felt power rising on him as well as on the girls. Elliot then said, "Ok, I know what to do now!"

Elliot shouted, ="MERMAID FUSION!!!"=

=He spun around with his arms stretched, and water shoots out from his hands and it covers them in a ball of water that is blurred; only the enemies, Lewis, Zane and Miss Chatham remain outside, and Emma, Cleo and Rikki swam around the ball. A glow of light shined from his forehead, and the mermaids fused with him one by one, with Cleo making his arms armor, Rikki, his legs armor, and Emma making his wings, helmet and upper and lower body armor.=

Elliot shouted, "Mermaid Prince, BORN!!!"

Then the water ball bursts and splashed on different directions. Charlotte and Dr. Denman were terrified, and Dr. Denman said, "Where did the mermaids go?"

Elliot said, "They're inside me now, so you can't hurt them!"

(Just to note: Elliot's Mermaid price armor is a blue and white variant of Genesic GaoGaiGar.)

=Charlotte attacked with her water powers but Elliot shouted, "SPLASH SHADE!!!" and a pond of thin water appeared from his palm and deflected Charlotte's attack. Dr. Denman gets a harpoon and attacks him but dodges.=

Miss Chatham said, "Elliot, time to rely on your sister and her friends' power. Try it." (Note the girls now act as his armor parts, so they can't move but can pass Elliot the weapons from the back armor.)

=Elliot nodded and said, "Emma, I'll need your help." Emma said, "Got it Elliot. Try this." Emma transferred him a part and Elliot shouted, "FREEZE KNIFE!!!" the part went to Elliot's left hand and reveals an ice knife and uses it to break her spear and freeze her hands too. Dr. Denman was shocked and said, "How can he do it?"=

=Elliot said, "Cleo, time for your turn." Cleo said, "Ok, try mine for size." Cleo transferred him a part and Elliot shouted, "MORHPING DRIVER!!!" the part went to Elliot's right hand and reveals a tube-like weapon and Cleo says, "Here's the tip." The tip of the weapon shoots out from Elliot's forehead and connects with the weapon, as Elliot flies upwards and dives downward to give a shocking attack to Charlotte. Charlotte later said, "That's not fair! How come you get them and I don't?"=

=Rikki told Elliot, Now use the grand finisher- mine." Rikki transferred him a part and splits in pieces, as the other parts go back to Elliot's back armor, and the little integrates on Elliot's hand to act as gloves and he shouts, "BOILING TIDAL AND CALM!!!" then, his left hand glows pink and the other hand yellow.=

=Elliot chants, "Gemu Giru Gan Go Gufo..." as he struggles to bring his hands together, and as he manages to bring them together, a horizontal whirlpool tunnel engulfs both Elliot and the two girls. His wings lift him up, as he was hovering, and he flies (still with two hand together) going towards the girls. He shouts, "VIIIIITTTTAAAAAAA!!!!" and the two girls get thrown away from the force of his attack.=

As he finishes his attack, everything fades away to normal, and both Dr. Denman and Charlotte were nowhere to be found. Elliot then said, "Wow, Did I just got rid of them or what?" then, his armor glows and it becomes a armor of light that separates in three which, after the light fades away from the three, reveals Emma, Cleo and Rikki back to normal (not mermaids).

Emma embraced Elliot and so did Cleo, and Emma says, "Thanks for saving us. I knew you'll do the right thing."

Elliot said, "I know Emma. Now I know why I was destined to be like you and your friends- to do the right thing. And that is to use our powers for good."

Cleo said, "Good to know. This deserves a kiss." She then kissed Elliot and Lewis said, "Um Cleo-"

She kissed Lewis too and she said, "Well I'll take both of you anytime. I love both you and Elliot. Unlike someone here who don't want it…" Rikki just said, "Ok you got me Cleo."

They all laughed, and Emma said, "We should all go home now. We might get searched for."

The next day

Emma, Cleo, Rikki and Elliot went to the beach. They saw Zane, Lewis and Ash and Elliot said, "Well we're off to swim. Care to join us?"

Zane said, "We're on it, but we'll just use the boat."

Emma said, "Well, ready to swim, little bro?"

Elliot said, "Well, last one to Mako Island is a smelly fish!"

Cleo said, "Oh Elliot you jokester!" with that said, and the girls giggling, they dipped on the beach and they began to swim. Now, they're not the only ones who's swimming as three of them, Elliot's joining in.

All four of them swim peacefully to Mako, this time, with their first merman in the gang, Elliot.

At last, this is over! If you guys read it right, the ones with a = means a GaoGaiGar reference was used in the story. Hope you guys enjoys it so review ok?

However, Emma won't be in the 3rd season of H20, so I made this a conclusion to the last episode as a connection to season 3. Hope you guys liked it!
