What's up everyone?! Ace Xavier here with a story inspired by a fellow fanfic writer, Hunter41963801. It will show the main character gaining a device similar to the omnitrix, allowing him to change into all different kinds of powerful beings. Now, on with the show.(I spin around quickly in my chair, before stopping, clearly dizzy.)

My name is David Hall. One minute, I'm enjoying a a nice day out. The next, I find myself in this weird shadowy place. "Shadowy place?! This is my home your talking about! Or thinking about, more accurately." A voice from behind me says.

I turn around to see a man lounging in a chair that looked like a mix between a throne and a recliner. Honestly, it looked pretty cool. "Thanks. Cool's what I was going for." He said. I grew more confused. "I can read your mind sometimes." He explained as he stepped into the light. He was 3 inches shorter than me and had black hair and glowing eyes. He wore a simple t-shirt, blue jeans, and grey tennis shoes. On his left wrist, there was a silver watch that I could swear looked high tech.

"Um? Who are you? Where am I? Am I dead? Are you God?" I asked. "Hey, hey! One question at a time, Hotshot. You aren't dead. And I'm not God. But, I do have a few tricks that could be considered godlike. One of which is bringing you here. The name is Xavier, Ace Xavier." He introduced himself. "Oh, James Bond reference." I said, a chuckle escaping. Xavier chuckled as well when he started to glow which flashed for a sec and in his place stood a young Sean Connery in a tuxedo and I think I heard the James Bond them faintly playing in the background. "Shaken, not stirred, Mr Hall." Xavier said in Bond's famous British accent, or was it Connery's Scottish accent. "You can shapeshift?" I asked, both as a statement and a question. He nodded and then changed back. "Who's to say that what you see before you is even my true look." He explained.

I then decided it was time to find out why I was truly here. "So what do you want from me anyway?" I asked him. "Well, my good man. An ally of mine, Hunter, occasionally sends one of his creations to pick a champion from an earth go out and do stuff in the multiverse, either help protect it or mess around or yada yada yada, you get the picture. So, I decided to get in on the fun and choose a champion of my own. And the lucky winner just happens to be…" He explained.

"Me?" I guessed. "That's right! He can be taught!" Before I knew it, he placed a graduation cap on my head and a certificate in my hand like Genie did to Aladdin. "Amber, show him what he's won!" Ace said in a game show host like voice.

In walks a female orangutan in a red sparkly gown, blonde wig, and high heels. If I wasn't confused as heck right now, I'd most likely laugh at this. She pushes something tall covered by a tarp. "You just won…a brand new face." Ace said as he wore a sparkly tux and uncovered the tarp to reveal a full length mirror.

I approached the mirror and stared at my reflection. Except the person who stared back wasn't me, it appeared to be the late Jason David Frank. "What the hell is this?!" I turned to Ace, who was back in his original clothes, while pointing at my reflection. I then realized I sounded like Jason David Frank as well. How did I not notice that before."Maybe it helped set up the reveal?" Ace gave his input. I didn't bother asking at this point.

"So, why do I look like Tommy Oliver?" I asked him. "Well, the champions of Hunter usually resemble actors from our worlds and I wanted to include that as well. So, Hunter suggested Jason David Frank." He explained. "Speaking of which, you may want to know of two you'd might run into." Ace added as he tapped on his watch and brought up two holograms. One appeared to be Tom Hardy while the other appeared to be the actress for Jean Grey in the original X-men trilogy. "These are Jason Krueger and Trinity Viper." Ace began. "Jason, also known as Mega Avenger, is a protector of his multiverse. He's strong, fearless, selfless, and loyal. He'd be quite the ally if you two were ever to meet." Ace informed me before he turned to Trinity's picture, and shuddering. "Trinity, however, is a killer running on pure evil. She calls herself the Demoness. Do not engage her unless you have absolutely no other choice." Ace said.

"But we're not here for them, we're here for you." He told me. "If you're going to be a guardian, you'll need a suit." He said with a grin as he brought me over to another tarp, which he immediately uncovered, and my jaw dropped and my eyes practically burst out of my head.

In front of us was a silver battle suit. The mask/helmet resembled a mix between the Mighty Morphin Green Ranger helmet and the 2017 ranger helmets, except without the dragon theme or mouth imprint. The torso was similar to the bat suit from the Dark Knight trilogy without the bat logo. A black cape, similar to Henry Cavill's in the DCEU, hung off the back. A black utility belt around the waist. His arms were similar to Iron Man's or Max Steel's, while his legs were more War Machine with BatFleck's boots. It looked undeniably badass.

"While you're busy trying to catch a fly, you should try the suit on." Ace said as he snapped his fingers. The suit immediately began to dissolve until the only thing left was the left wrist. A closer examination of it showed some kind of watch face. The watch floated over to Ace who had it hover over his hand while spinning it, before he shot it at my left wrist, turning it into a gauntlet of some kind. It almost looked like a silver version of the ultimatrix from Ben 10.

"Wow." Was the only thing that could escape my mouth. I pressed the dial down and in a flash of light, the suit formed around me. I had a HUD system like Iron Man, which made everything look even cooler. I then retracted my helmet and looked at the gauntlet. "So, to help the multiverse, you gave me the power to change into Ben 10 aliens?" I asked Ace. He grinned. "Not quite. This watch will grant you the form of any hero or villain, along with any weapon or vehicle from any movie, cartoon, tv show, anime, or video game. Along you moving you between dimensions. And a bunch of other cool stuff you can check out later." He said, baring a huge smile on his face. I struggled to contain my excitement.

"Observe, my champion." He said as he tapped on his watch as many small glowing orbs floated out of it, soon surrounding us both. The orbs glowed brighter and expanded a bit. I looked in some of them and saw what they held.

In one, I saw Fire God Lui Kang facing off against Elder God Kronika. In another, I saw the Snyder cut version of the Justice League vs Steppenwolf. The battle between Ash's Pikachu and Leon's Charizard. Obi-Wan vs Anakin on Mustafar. Sam and Mikayla meeting the Autobots. The Arrowverse heroes against the Dominators. Aang in his final battle against Ozai. And one even had that one Bugs Bunny cartoon where he was pretending to be a barber fixing up Elmer Fudd.

"How is any of this possible? They're supposed to be fictional." I asked him. "Have you ever seen the Ducktales reboot?" Ace asked. Okay. Weird time to ask that question. "Yes? Why?" "Well, in the show, they explain that television shows are sort of windows into alternate universes. My champion, I've discovered that to be true. Along with movies and video games as you can see." He explained. "And what do you want me to do?" I asked. "I want you to help protect the multiverse. Protect the innocent. Knock the arrogant down a few pegs. Maybe even annoy a few people. And most importantly, have fun. You don't need to be a hero. You don't need to be a villain. Be the protector the multiverse truly needs. Be the Omni Defender." Ace explained.

"The Omni Defender?" I repeated, first in amusement, but then I thought about it. "That does sound badass." I told him. "Glad you think so." Ace said before a portal appeared behind him. It sorta resembled a cross between the vibe gates from The Flash and a groundbridge from Transformers Prime.

Ace stepped aside, gesturing toward the portal. I stepped into it and then turned back to him. "Will I ever see you again?" I asked. "If it's continent." He chuckled. "Then I guess this is goodbye for now." I said. "Yes. Goodbye." He began before changing into a young Leonard Nimoy with pointed ears. "And live long and prosper." He finished with the Vulcan salute as the portal closed.

(Wipes sweat off forehead) Phew! That took longer than expected. But I'm finally down with the first chapter. I hope you enjoy it and feel free to check out Hunter41963801 and his stories, they're the inspiration for this story. Now, here's a thing to know about David. With his watch, he'll be traveling the multiverse, which contains different movies, tv shows, and video games, so make sure to give plenty of suggestions for which worlds you'd like to see David go to and who you'd like to see him change into. As much as I don't find them to make since David will have a harem, so include who you'd like to see(just don't include anyone to young or old, David's in his 20s-30s).
