Heroes United

***Heroes United*** is the twenty-fifth *Ultimate Alien* chapter of *Clock 10: Choose Your Own Adventure*.

## Plot

The epsiode opens with Clockwork Firefly being on a talkshow opposite Will Harange. As usual, Harange is twisting Clock's actions as a hero to make him seem like the bad guy, specifically referencing events from *Video Games* and *Hero Time*.

The talk show is interrupted by an orange portal opening up in the studio, with a large, mechanical beast exiting it. Clock becomes Rath to attack, but the creature grabs and zaps him before both are pulled back through the portal. Rath is flung towards the exit, and flies out over New York City, only for something else to come flying at him.

The thing flying towards him attacks, knocking him to the ground. Rath looks up as the smoke clears to see the silhouette be of a young man (Rex Salazar) just as his gigantic metal arms become normal. Rath becomes human which surprises and confuses Rex, asking if Clock is capable of controlling his Nanites.

This confuses Clock as well, but Rex is contacted via earpiece, and the two of them decide to team up to fight the creature from the portal. Reaching the city, they find Agent Six attempting to fight it. Clock goes Big Chill then his Ultimate form, but is defeated. Rex goes to attack, but Six destroys the creature while also knocking himself out. The two then retreat to the headquarters with Six.

Clock is then stuck within a large green tube, as Rebecca Holiday enters. She assures him he's not in trouble, just that his biometrics need scanning given his conversation with Rex. Rex then enters and asks about Six's condition, Holiday revealing that Six has been put into a coma due to the direct impact of the explosion. When Clock's biometrics finish, Rex and Holiday are surprised to find that all of the Nanites in Clock's system are freshly added, and that they've nothing to do with his powers.

After being let out of the bio-tube, Clock explains the situation regarding the Ultimatrix, though Rex is skeptical about the idea of aliens. Holiday explains the Nanites being in every living creature (aside from one White Knight) and that most are inactive. The active Nanites create E.V.O.s, which typically are giant monsters, aside from Rex, who is able to control his Nanites into his builds, as well as "cure" the Nanites of most E.V.O.s to restore their original form.

White Knight grabs their attention, leading them back to the main area. A large screen displays security footage of the fight, revealing that the beast's physical form was destroyed, but whatever was controlling it is still out there. White Knight sends Rex and Clock to go patrolling to lure this thing out. They take to the skies with Clock as Stinkfly. While on patrol, the two spot a ship landing near Steamed Ham Royalty (a counterpart to McRonald's) and Rex opts to head for it.

The ship opens up, reavealing Rex's older brother Caesar, who fires off a weapon which Rex blocks using the Block Party. Stinkfly attempts to slime Ceasar, but he blasts the slime away, and reveals the weapon's target was meant to be the E.V.O. behind them. The E.V.O. dies, and a red, gaseous creature spawns from it. As the creature inquires about the world around it, Caesar instructs Stinkfly to divert its attention away from Rex for it to be destroyed. Stinkfly attempts to distract the creature with a song, which results in it becoming annoyed and throwing him. Caesar blasts the creature, causing it to dissolve, but remarks that it won't last for long with the weapon not fully charged, and for them to leave.

As Ceasar's ship takes off, he charges the weapon, and explains that the creature is the Alpha Nanite, the first one ever created. The Alpha Nanite gained sentience after creation, and was banished to the Null Void just before the Nanite Event. Clock, as a human again, comments on having experience with the Null Void, and that leads Caesar to theorize the Null Void as being the link between their worlds. Clock offers to team up with Rex, but Caesar insists Rex stay away from Alpha for fear of it absorbing Rex's Omega Nanite.

Caesar asks for Clock to keep Rex out of trouble, but despite his concerns, leaves through an escape pod, setting the ship to self destruct to get Alpha off their tail. Clock becomes Goop and uses his body to surround Rex, protecting him from the blast before bringing both of them to the ground. Rex gets a call from Holiday telling him Alpha has arrived at the base.

The two head back to the base, with Rex saving Holiday from Alpha's grip with use of th B.F.S., sending her flying through the air for Clock to save her as Ghostfreak. Ghostfreak attempts to attack Alpha but to no avail, though Alpha's anger leads to Rex landing a hit on him with a shot from the Slam Cannon. Ghostfreak becomes Snark Tanque, attempting to distract Alpha away from Rex. This proves effective, as Alpha's attention is taken long enough for Holiday to blast him with a weapon that disperses him.

Clock and Rex relax some during a non-competitive game of basketball, discussing their pasts as heroes. Clock even goes so far as to suggest looking into other universes to make a group of superheroes. Their conversation is cut off by White Knight contacting them about something happening at the Bug Jar, which is explained as being a contained area of dangerous E.V.O.s in what used to be Kiev, Ukraine. The two go to head out, only to temporarily mix up their jackets.

Reaching the Bug Jar, Clock becomes Humungousaur, just in time for the group to witness Alpha absorb the Nanites of an E.V.O., with Alpha now in a much larger, more stabilized form. Humungousaur attacks, but is thrown about like a ragdoll. Rex summons the Funchucks, which gains Alpha's attention to the presence of the Omega Nanite.

Alpha turns his attention back to Humungousaur, and then uses his abilities to copy the Ultimatrix, sending Clock back to his human form. Alpha activates the device, becoming an E.V.O. version of Swampfire, Alpha Swampfire. Clock attempts to transform, unintentionally becoming Gutrot. Gutrot uses sulfuric acid gas on Alpha Swampfire, which he retaliates against by launching Gutrot into the air. Mid-air, Gutrot unintentionally transforms into Bloxx.

Bloxx is incapable of fighting Alpha Swampfire, but rebuilds himself after an attack. Alpha Swampfire then becomes Alpha Spidermonkey. Bloxx hits the Ultimatrix, becoming Shellhead, then builds up his kinetic energy through fighting with Alpha Spidermonkey, then knocks him into a building with a kinetic explosion.

Rex shows up and suggests that he use his cure power on Alpha's Ultimatrix, but that Clock will need to keep him down. Rex uses the Blast Caster to whip Shellhead around, building up his kinetic energy. The two are then caught off guard as Alpha emerges, having transformed into Alpha Atomix. Shellhead hesitates, believing that using his power would be dangerous against Alpha Atomix.

Alpha Atomix mixes his abilities and creates smaller, nuclear-powered E.V.O.s that rush Shellhead and Rex. Shellhead hits the Ultimatrix, resulting in him becoming Gravattack. With Rex's guidance, Gravattack pins Alpha Atomix to the ground, and Rex lands on him with the Punk Busters before curing him of the Ultimatrix copy. Gravattack's Ultimatrix flashes and sends him into his human form unintentionally, and Alpha stands up with a hold on Rex. The Ultimatrix fails to transform Clock, and Alpha successfully absorbs Rex's Omega Nanite, becoming the Alpha-Omega.

Rex fills with grief, believing to have failed. Clock disagrees, and after a little bit of messing with the Ultimatrix, successfully gets Upgrade, and merges with Rex, giving him the Upgrade Suit, and using the B.F.S. (now dubbed the Alien Excalibur) to demonstrate their combined powers. Using the Hyper Jet (Boogie Pack), the two fly off to face Alpha-Omega, blasting him with the Hyper Jet's energy rockets.

The two use a variety of Upgraded versions of Rex's builds to combat Alpha-Omega, including severing his limbs with the Alien Excalibur. However, an attack with the Blast Launcher (Slam Cannon) destabilizes Alpha-Omega into a gigantic mushroom cloud, and Upgrade and Rex are sent flying back, with the former becoming human again. Caesar arrives, calling the situation "opportune." He gives Rex a device that aims right at the Omega Nanite within Alpha-Omega, which gives Rex an idea.

Caesar connects the device to Rex's goggles, and Rex creates the Slam Cannon. At Rex's suggestion, Clock becomes Shellhead again, and is fired at Alpha-Omega via the Slam Cannon. Shellhead hits right on the Omega Nanite, causing Alpha-Omega to disperse as Rex cures him, absorbing the Nanites and leaving Alpha-Omega in a tiny dense ball. Caesar says the ball is dense enough to keep Alpha secure, and extracts the Omega Nanite. He then uses a dimensional gun to open up a portal to the Null Void, which Clock can use to return Alpha, and then return home.

Clock and Rex share a goodbye, which includes Clock giving Rex some narcotics. Clock becomes Slapback and duplicates to lift the Alpha sphere, taking it back to the Null Void before returning home.

* This is the first canonical crossover for *CYOA*.
	+ If the spin-off is counted, then the first would be *Ben X*, crossing over with the canon series.
* The Omni-Kicks were named by Grounder, as a nod to the Omni-Kix. This name was made out of necessity, as the Punk Busters did not get an Upgraded variant in the actual version of the crossover.
	+ In this version, the Rex Ride's Upgraded variant, the Swift Rocket, does not appear.
