Abi had a secret, a secret that no one knew, not even Optimus. Abi had just walked out of school, she saw Jack and Arcee drive away, She also saw Bee and Raph drive off, but as she looked around she saw that Optimus was not here, he was supposed to pick her up.

She waited for ten minutes before she finally decided to walk home, just as she began to walk Optimus drove round the side of the school and parked in front. Abi walked towards the truck and climbed in.

"My aplogies for being late Abigail"

"Its okay"

Optimus began his drive and Abi got a head start on her homework. It was a long drive and she completed her homework, now she could have a worry free weekend. Optimus drove into the base and parked, Abi got out and went up and joined Jack and Raph.

"What took you guys?"

"Optimus was late, no big deal"

Raph and Abi began to play a video game, he would usually play with Bee but he was busy with Optimus.

"Its dangerous Optimus" said Ratchet

Abi paused the game and walked towards Optimus "What dangerous?" she asked

"A cybertronian relic is at the side of what you call the mareana trench and we must get to it before Megatron" explained Ratchet "But we bots are not build for water"

"Right, you would sink to the bottom with no way of getting back to the surface"

"Precisley"

"Only the power of a prime can disarm the device, I have to go Ratchet"

Bee beeped, Abi had no idea what he said But Raph did

"No Bumblebee you will stay here, I will go alone"

Bee beeped sadly

"How much water pressure can you guys handle anyway?" asked Abi

"We can go precisley six thousand meters down" said Arcee

"The trnch is much further than that if you fall you'll get crushed and besides its a shark breeding ground"

"Still I must go"

"But how will you get back?" she asked worried for Optimus

"I will find a way Abigail" he said leaning down so he was face to face with her "Do not worry"

"Ratchet open the groundbridge above the location"

"I hope you know what you're doing Optimus" said Rathet as he opened the portal.

"Be careful Optimus"

Optimus looked back at Abi and smiled, then he walked through the portal.

"How long until he gets to the relic?" asked Jack

"An hour"

"Can we speak to him?" asked Raph

"He can hear us but he cannot talk but we can see what he sees"

"How?"

"This" he said as he pressed a button

"Did you just Hack Optimus's eyes?" said Abi

"In a sense yes"

"Cool" said Jack

An hour later the others saw that Optimus had reached the bottom of the ocean floor, they could see the entrance of the trench, Optimus began to walk around with his lights on trying to locate the device, when Abi noticed something on the radar.

"Ratchet what is that?" she asked pointing at the sceen

"I'm not sure, Its big what ever it is"

"Optimus watch out, something big heading towards you" said Abi over the comms

The team noticed that Optimus turned around, what they saw scared them, It was a giant great white shark.

"Optimus!"

The shark rammed into Optimus and he grabbed on trying to steady himself but the shark was pushing him towards the trench.

"Ratchet open the ground bridge in the same location as before!" exclaimed Abi

"Excuse me?"

"OPEN IT!"

Ratchet opened the bridge and Abi ran through, she was falling towards the ocean, she used her magic to become what she truly was, a mermaid. Her black tail seemed to sparkle in the sunight. She swam as fast as she could towards Optimus, it took her mere sceonds to arrive at the bottom on the ocean, she could see Optimus still clinging to the shark. She swam towards it and used her magic to create a bubble wall between it and Optimus.

Now the shark was coming for Abi, she did the same thing again but this time the wall was around her self and it scared away the shark. Abi watched as it swam away, she turned around to see Optimus staring at her, she waved at him and swam closer to him. He was shocked to say the least.

Abi noticed something in the corner of her eye, she swam over to it and picked it up, it was the cybertronian relic he had been searching for. She swam back over to Optimus and placed in his open hand.

His chest opened and a bright green light emerged and the relics lights tuned off. Abi looked at Optimus who's eyes went wide, she turned aorund to see a pod of Mermaids. Abi swam up to them and they seemed to be talking to eachother. 

Minutes later the pod surrounded Optimus, Abi postioned her self infront of the bot, the mermaids used their combined magic to lift Optimus, they swam up towards the surface of the water.

When they reached the surface Abi saw a ground bridge open and an arm that resembled Bee's was sticking out, Optimus grabbed the hand and Bee helped him through the ground bridge, but before Optmius went through fully he scooped up Abi. Abi and Optimus landed in the base, Optmius opened his hand and Abi had legs again. Optimus put Abi on the gorund and stood up.

"Abi!" SHouted Raph as he ran up to her and hugged her

"Hey"

"Are you alright?" asked Jack

"Yeah but I still hate sharks"

"Why didn't you tell us you were a mermaid?" asked Raph

"It wasn't just my secret to tell, I'm sorry I lied to guys"

"Thank you for saving me Abigail" said Optimus

"Anytime, I wasn't gonna let you get crushed by water pressure"

"How did you swim down that far?" asked Raph

"Water pressure doesn't effect me and I can breathe underwater"

"Cool"

"So what exactly does that device do?" asked Abi

"It can turn any solid Material into any other solid material" said Bulkhead

"So like it can turn Rubber into Gold?" asked Raph

"Exactly"

"Cool"
