Ancient Mayan Temple

Zatanna and Dr. Fate are fighting against the ancient Mayan Monsters who are guarding the Dominus Librium. Dr. Fate is fending off the Mayan Monsters by using his magic ankh beams towards the monsters while Zatanna is going after the artifact itself: The Dominus Librium. Zatanna run towards the stairs, where the Dominus Librium is right above the "pyramid".

Zatanna: (while running up the stairs) God I hate stairs...

Zatanna finally grabs the artifact, then realized whenever the artifact was taken, the temple will colapse. Zatanna quickly run towards Dr. Fate after defeating the ancient Mayan Monsters.

Metropolis

Ultimate Humungousaur and Monster Kevin are exchanging fists each other. Then Ultimate Humungousaur launches his missles hand, but Monster Kevin turns himself into a smoke; courtesy of Metamorpho's power (Monster Kevin already absorbs Metamorpho's powers). Then Monster Kevin uses Atomix's power to create a ball-shaped atomic blast towards Ultimate Humungousaur. The blast exploded towards Ultimate Humungousaur; which leaves him unconcious and turns him back to Ben, who's injured and his shirt is somewhat got shred. Finally, Monster Kevin grabs Ben while creating a blue flame from his left hand.

Monster Kevin: Don't worry, I'll make this quick.

When Monster Kevin about to finished off Ben, a red-and-blue blur knock Monster Kevin far away then catches Ben. It's Supergirl, who's worried and carrying Ben far away from Metropolis.

At a several hundred feet on the air, Ben has regain consciousness and realized that his girlfriend, Supergirl, was carrying him under his arms while flying away from the fight.

Ben: Uuugghhh... Kara?

Supergirl: Its okay, I got you...

Ben: Wait, I've gotta go back to stop Kevin. He'll-

Supergirl: I know. But you're in no condition to fight. Beside, Zatanna and Fate already got the artifact.

Then Monster Kevin are flying towards Supergirl and Ben to chase them down.

Monster Kevin: (yelling) I'm not through with you Tennyson!

Monster Kevin uses Superman's heat vision (after absorbing Superman's power) to shoot down Supergirl and Ben, but Supergirl kept on dodging him. Then Ben realized something about Supergirl

Ben: That's not like you to avoid the fight...

Supergirl: I don't but Dr. Fate have something important to stop this Kevin guy. Besides, you're more important right now...

Ben has a blush on his face, while Supergirl is carrying Ben while trying to get away from Monster Kevin.

Tower of Fate

Realizing the Tower of Fate has no windows nor doors, the portal to go inside the Tower of Fate opens itself when Supergirl flew quickly while carrying Ben, but closes when Monster Kevin is closing in. Monster Kevin tries to find a way to enter the Tower of Fate by smashing it, but it was protected by a magic barrier.

Monster Kevin: (frustrated) You can't keep hiding forever Tennyson!

Inside the Tower of Fate, Supergirl is tucking Ben on a bed to get some rest. Then Zatanna and Dr. Fate is explaining to Supergirl about the plan.

Dr. Fate: I'm going to be a middle of my spell to access the Dominus Librium. This is the only thing that will cure Kevin. But it will take time since this artifact is made by aliens

Supergirl: Great, so how are we going to delay Kevin?

Ben: I'll "delay" him...

Supergirl and Zatanna surprised to see Ben to get off from the bed quickly

Supergirl: Ben, you're in no condition to-

Ben: I'm "traught", "whelmed", and feeling the "aster". I'm going... Great, now I sound like Grayson...

Then Supergirl placed her hand on Ben's shoulder and giving him a glare

Ben: Don't give me that look. You know that I have the power to transform into different aliens to stop Kevin. He may have all my aliens' powers, but he can't "steal" those powers. You know that he'll come to absorbed more powers if he wasn't stop.

As much she hates seeing her boyfriend get injured again, she knows that Ben is the only one who can stop Kevin

Supergirl: Fine, but you're not coming alone.

Zatanna: (to Ben) plus your clothes are shred and your injured. But I can fix you up.

Then Zatanna put a spell to Ben to quickly recovers

Zatanna: Laeh mih dna xif sih sehtolc

Zatanna use her spell to heal Ben from his injuries and fix his clothes.

Ben: Thanks Zee. Now lets kick some ass...

Ousite the Tower of Fate, Monster Kevin is waiting for Ben to come out. Ben, already transformed into Echo Echo, then evolved into Ultimate Echo Echo, came out from the tower along with Supergirl and Zatanna, while Dr. Fate is working on his spell to active the Dominus Librium. Supergirl and Zatanna are both floating in the air.

Ultimate Echo Echo: This ends now Kevin!

Monster Kevin: Couldn't disagree...

Monster Kevin uses Black Canary's scream towards the three heroes, but Ultimate Echo Echo uses his Sonic Waves from his hands which his more powerful the Black Canary's scream to counter Monster Kevin.

Monster Kevin got pushed away by Ultimate Echo Echo's scream and hits the trees on the forest.

Ultimate Echo Echo: Supergirl! Zee! Whatever you do, don't let Kevin touches you

Zatanna: Got it! (then she look towards Monster Kevin) Egnahc eht sehcnarb otni sgnidnib!

Zatanna uses her spell into ensnare Monster Kevin with branches.

Monster Kevin: (smiled) You think you can hold me with trees? I'm not impressed...

Monster Kevin released green spored-gas from his hands (from Swampfire's power) to control the trees and pull Zatanna to the ground and ensnare her.

Zatanna: Sehcnarb, emoc - Hmph!

Zatanna was tied and gagged by branches ensnared by Monster Kevin, which makes her unable to use any magical spell.

Supergirl was flying towards Zatanna to help her, Monster Kevin uses Gravattack's power; using his gravikinesis powers to plummented Supergirl to the ground. Then Ultimate Echo Echo flew towards Supergirl and Zatanna to help them both, then Monster Kevin uses Brainstorm's electrokinesis from his forehead to blast Ultimate Echo Echo and knock him away.

Despite Monster Kevin is using Gravattack's gravikinesis power, Supergirl is struggling and crawling toward him. Then Monster Kevin give a little smile on Supergirl, knowing that she's just another "meal to devour". So Monster Kevin quickly grabs Supergirl and absorbs her powers, then released green spored-gas from his hands again (from Swampfire's power) to control the trees and ensnare Supergirl after losing her powers.

Both girls are out of the way, now its only Monster Kevin and Ultimate Echo Echo.

Monster Kevin: Now, no more distraction! Its just you and me.

Monster Kevin uses Diamondhead's crystal shards towards Ultimate Echo Echo, but Ultimate Echo Echo uses Sonic Force Fields to blocks the crystal spikes

Monster Kevin: (while shooting crystal shards) You've turned me into a freak! Now you've come back to Earth to become a world famous superhero!

Then Ultimate Echo Echo's Sonic Force Fields breaks after no longer able to hold off the crystal shards.

Ultimate Echo Echo: I never ask to have this "hero life". Between you and me, I thought you and I can be friends instead of being a jackass..

Monster Kevin: My heart bleeds for you! And now, you've just bleed!

Monster Kevin is using Lodestar's Magnetokinesis power to control Ultimate Echo Echo. Ultimate Echo Echo resist it but caused his "skin" got cracked due to his vulnerability to magnetism. Had enough, Ultimate Echo Echo make his final move.

Ultimate Echo Echo: I'll make this as painless as quick as I can...

Then Ultimate Echo Echo throws his sonic disks, then it duplicates itself and surrounds circles around Monster Kevin

Ultimate Echo Echo: Sonic DOOOOOMM!

The Sonic Doom unleashed circles around Monster Kevin. Cannot withstand it, Monster Kevin screams in pain and fell down unconsciously.

Then Dr. Fate teleports himself through the Golden ankh shape, then finally able to uses the Dominus Librium to cure Monster Kevin, while Ultimate Echo Echo pressed the Ultimatrix dial to transformed into Diamondhead then free Zatanna and Supergirl from the branches bindings.

The Dominus Librium works; it cures Kevin to turned him back into human again, but still unconcious. The cure also released all the energies that Kevin have stolen, and all the powers stolen by Kevin have been returned to their owners.

A few hours later, after the authorities came to pick up Kevin. Then Supergirl approaches Ben.

Supergirl: Ben?

Ben: Yeah?

Supergirl: There's somthing that I would like to tell you.

Ben: What is it?

Supergirl: I've made my decision. (then taking a deep breath) I... I want move in with you...

Ben: Wh... What? (then blushed super-hard) A...Are you sure? I mean do Clark and the Kents don't mind if-

Supergirl: I've already talked to them... Clark will help me to bring my stuff to your apartment..

Then Zatanna gave a nudge on the shoulder towards Dr. Fate, showing a "signal" that they shouldn't bother Ben and Supergirl. Deep down, feeling exited after overheard that Ben and Supergirl are taking their relationship to the next level

Zatanna: (to Dr. Fate, while smiling) I think we should leave...

Dr. Fate open an ankh-shaped portal then goes through it along with Zatanna.

Ben: Kara, I never get the chance to say this... but uhmm... (still blushing). I. Love. You.

Supergirl: (also blushing) I love you too...

Then Ben and Supergirl shares their kiss...
