All those times I had to be reluctant, I can't swim, I was holding onto Scooby's tail to make it look like I was swimming!", Shaggy asks, "Like, have you ever had a diving instructor?", Velma shouts, "No, everyone of you can handle the mystery, I'm just going to stay in the Mystery Machine, so I won't be near any mysteries that are sea-related!", Velma storms off into the Van, while Fred states, "Okay, then, Velma, i'll substitute for you and say your catchphrase and use my wits to try and figure out who the culprit is!", Daphne confusingly asks, "Are you really going to pretend you're Velma?", as the gang walk off, Shaggy and Scooby say one last thing to Velma that anyone can be a coward sometimes even if it's a ghost, after they left, Velma gets into the Van and thinks to herself how she can be a coward for being afraid of water, and not overcoming it, as Triton oversaw the gang are not here, he uses the Compass to magically turn Velma's eyesight fully working, as she removes her glasses, and is alerted by Triton's voice that she must go into the ocean to enter a gateway that will lead her to Atlantica, Velma being reluctant decides to start up the Mystery Machine close to the docks, as she stops at the end of the docks, she just jumps into the water.

Back at the surface, Trident presents a pink crown for Tatsu, who is hesitant to wear it, she said she swore an oath of silence after her master was assassinated by Takeo, when she arrived in America, she was always silent and people bullied her and called her, "Little mermaid", making her an Outsider, Trident comforts her and says she will have her sisters, and that she may speak freely when she is a mermaid and will not worry about being bullied, reluctant, Tatsu puts on the pink crown and the magic starts glowing and sparkles start swirling around her body, her black hair waves around her to cover her schoolgirl uniform to reveal pink seashell bra, she opens her eyes just in time to see her legs become pink fins, she is shocked for a moment, but becomes amazed and elegant to see her new form, admiring it, she jumps into the ocean.

Meanwhile at Mercy Reef, Batman interrogates Durham for mocking Katana, and Black Lightning tells Batman that Katana never speaks after master's death, and when she arrived in the USA, she was bullied, no name spoken, no lips moving, just silence, Slug even took advantage of it by reminding her of how she was mistreated, which made her become an Outsider. Aquaman came out of the ocean and tells Batman he couldn't search for her anywhere in the deep and that she might've disappeared. Curious, Batman raises an eyebrow in suspicion.

Believing that he might've kidnapped Julie, he accepts.

Next, Triton gives Kitty a blue hair braid that will hold her ponytail up, Kitty states, "Daddy, I made some friends on land, they were really good friends, but they don't seem to understand me because of how I drive, and how I cook and how I do everything which they find ridiculous, I don't think I fit in with them", Trident tells her she fits in with her sisters, she looks at Velma, Tatsu and Julie for a minute, and then at Artemis, Kara and Kory, she then puts on the hair braid holding her ponytail up and the magic starts glowing and sparkles start swirling around her body, her legs are replaced by blue fins and her pink blouse is replaced with a blue seashell bra, she is shocked for a minute, but is then amazed of her new form, and she dives into the ocean.

Scott believes she could've been kidnapped.

Next Trident gives Artemis a red hair braid, she then reminces the beach in Honolulu, Artemis and Aqualad discuss the two siblings, Peggy and Randy Eiling, and fatherhood in general—Artemis posits that being a biological father doesn't make him the actual father, as honesty and parental skills have not much to do with biology.

You cared for your people in Vilgaxia", Vilgax states, "Wrong, I was only playing them to show them I "cared" for their safety, I was never a heroic ruler, I was intergalactic tyrant, I only planned a hostile takeover on the planet Vilgaxia truly was called, Planet Murray, a planet ruled by a peaceful people called, the Muranians, who wanted peace and care as I conquered their planet and overthrew their king to rule it, but they rebelled against me by the time I returned, but not before I went to Galvan Prime, to steal back Ascalon, I saw something in my head when I absorbed the embodiment of power, Diagon, a mere illusion that was faked, I learned, Diagon and I were one, his power was once mine, my true power, and this place is my dimension, my true Vilgaxia, I was a god", Ben is fed up, "Enough!", he slams the Omnitrix to turn into Fourarms shouting, "I do not have time for this!", he punches Vilgax, "There's no way you're taking the whole planet Earth as your own Vilgaxia", he charges at Vilgax, while Vilgax charges at Ben as they collide, they have the same fight in Enoch's dream world, with Vilgax standing up after being defeated, Ben shouts, "Give it up!", Vilgax states, "Remember when I held you captive on my ship, before you turned into XLR8, I was feeding to you to my Squid Monsters", he summons a Lucubra, Ben questions, "What does the Lucubra have to do with you feeding me to your pets?", Vilgax chuckles, "Doesn't ring a bell, Ben?

We were in the same missions, you, me, Kevin, your boyfriend?", Gwen ruthlessly stating, "Yes, by the time you put back on the Omnitrix since the day Grandpa Max "disappeared", I was the one responsible for the DNAliens by using aquatic animal DNA, and after the Highbreed Invasion was over, I caused many events such as the Lechorian Virus in the Omnitrix", Ben shocked at that confession, "Gwen, you are a Lechorian Robot", Gwen violently states, "That's not all I've done, one year after you took the Ultimatrix from Albedo, I was also the one responsible for Aggregor and Kevin's Mutation, and I took Vilgax's embodiment of power from his body to pretend Diagon was real", Ben shocked, "So, you created the illusion of Diagon? And Aggregor was actually Will Harangue", Gwen maliciously states, "There were many other incidents with you and Rook, when I left for College with Kevin, I was the one responsible for the events you and Rook participated in such as Malware A.K.A. Ship", Ben saddened by this, "Gwen, why? Why would you do this?", Gwen reveals, "Because Kevin created me as a way to play you for a fool, to make you think he changed his ways, he discovered me when you left the Mega-Cruiser by Slix Vigma, after Technorg left beating him, Kevin discovered me as my leech went through his temple absorbing him to encounter your stupidity", Ben shocked at this questioned, "So all this time, Kevin was the dragon George fought, and he took Vilgax's true power from him to create the illusion of Diagon, and I've fought Vilgax's son?!", Ricoronis states, "Yes, my father was a great warrior then you came along, with the ability to conquer worlds, when Kevin, or should I say, Val Khan, confronted him as a dragon, he was tryinh to strip him of power, enabling him to remain underwater until he could find a way to look more humanoid, Val Khan was a Dragon Lord who wanted to please his biological mother, and he did that to play you for a fool by stealing her robots, the Lechorians, as your Uncle Frank Tennyson wanted a better daughter, knowing the imperpections of control", Robot Gwen stated, "We've done enough, now release me from your control", Ricoronis states, "But wait, it gets better, Khan and Professor Paradox altered the worlds by using the Clock stolen from a Time Emperor, and Paradox wanted to give you the same future by marrying you off to Kai Green, by using your son, Kenny as the Chrono-Spanner", Ben fell to his knees in humiliation, "Paradox altered the worlds? My son was his pawn and you mean to tell me Kai was supposed to his mother?", the Robot shouted, "Release me!", Ricoronis states, "Yes, in fact, sending Billy Billions posing as that French photographer to keep Julie away was brilliant, and Kevin knocking out Argit to prevent you from knowing you were going to marry Princess Looma, as a way of distracting you, and Elena Validus was created by Kevin, Jennifer Nocturne was probably Captain Nemesis' daughter, knowing how her blonde hair was actually dyed, Ester dating your cousin Sunny's ex-boyfriend, or maybe Sunny was a replica of the Robot, and then your half-cousin, Eunice Tennyson, made from probably the Robot's DNA to preserve all Omnitrix Alien DNA to help adapt the Lechorians become stronger and removing peace from the world, yes, the Robot's one true goal", the Robot shocked at Ricoronis exposing her plans, "NO! This isn't supposed to happen, you were supposed to free-", the Robot was having a headache from Ricoronis' powers, "I know all your tricks now, abomination, I know what you were trying to plan, double crossing me, well, this time it won't work like you double crossed the other scoundrels such as and the truth of the Lechorian Robot", the Robot was smoldering from Ricoronis burning her head and she is blown up, "Such pain to suffer, doesn't it, Ben?", Ben was kneeling in his humiliating defeat as tears fell down his eyes in anger, having been hurt by Ricoronis' taunting and Paradox, Kevin and the Robot's revelations, he angrily shouts, "NNNNNNNNNOOOOOOOOOOOOOOOOOO!!!!!!!!!!", as he slams the Omnitrix to turn into Way Big, who starts trying to crush a shocked Ricoronis, only stepping on the Robot's destroyed body and head one time, and Ben shouts, "I'm going to crush you so hard you'd wish you'd never taken your father's place!", as he starts wrecking his city, Ricoronis then touches the water from above and starts absorbing it's powers to take his true form, only different, he gains a body to destroy Ben and fight him in a clash of titans like how Ben fought Albedo as Evil Way Big, having both packed punches and blood slipping from their lips, they start activating each of their powers to defeat each other, Ben uses a hyper beam, while Ricoronis uses his eye beams, and they both end up defeated as an explosion destroys much of his city, as the smoke clears, Ben is bleeding from his lips with his clothes nearly torn, while Ricoronis, stuck in his true form is weak without Ascalon and tries to take it, while Ben limps over to get it, both try to their best to reach the sword, and Ben puts his hand on the sword and touched it to stand up straight and he picks it out of the ground in triumph, Ben tells the Omnitrix to take him to Galvan Prime, as it did, he then sees the saddened looks of Max, Rook and Azmuth, who saw everything Ricoronis said and was True.
