The Justice League and Avengers had barely locked away Homelander and his team when the city came under siege again. This time, it wasn’t some petty villain or egotistical superhero wannabe causing chaos. It was Ultron—wielding all of the Infinity Stones and backed by new bizarre allies.
As the battle alarms blared across the Justice League’s headquarters, Iron Man found himself at the center of the scolding. Thor, in particular, was livid.
"Stark! Is this your doing? Again?" Thor's voice boomed.
Iron Man threw his hands up defensively. "Whoa, hold on! Not me! This isn’t my Ultron. This one’s from Earth-616. Not my responsibility. I haven’t even built a crazy robot yet in this timeline!"
"Still feels like your fault," Thor muttered, his hand tightening around Mjolnir.
Flash, zipping around the room, added his commentary. "Honestly, this Ultron guy’s bad, but nothing like that Yogiri we dealt with. That guy was a nightmare."
Rimuru chuckled, finishing the last bite of his beef. "Yogiri was just annoying. I’ve kicked his ass enough times, added some extra pain for good measure. Dude was always prattling on about gravity and non-existent physiology like it was some big deal. His fans really hyped him up too much."
Cyborg, still recovering from almost being hacked by Ultron earlier, chimed in. "Yeah, I nearly lost control of my system. Lucky for me, I’ve got a soul, unlike your usual robot. Managed to fight him off using my mind before he could take over."
Ultron wasn’t just any version they quickly realized he had upgraded his body with Uru metal, making him nearly indestructible. With the Infinity Stones in his possession, he was capable of traveling between realities, making him even more dangerous. Ultron wasn’t alone either; he had somehow enslaved a kid named Izuku Midoriya and some omnipotent being called Zeno, who now served him like mind-controlled puppets.
And then, there was this "Life Rider" character. Thor’s confusion only grew as this newcomer spouted nonsensical power-scaling ramblings.
The Life Rider, dressed in some weird armor, entered the scene, giving a long-winded monologue. "You see, Ultron, the concept of space-time is only 3D. I have deduced that beings who create space-time are 3D beings, at best! The multiverse? Just a stack of 3D realities. It’s all about perception!"
Thor’s brow furrowed, his confusion growing. "What in Odin’s name is he talking about?"
Rimuru, already annoyed by the Life Rider’s nonsensical logic, cracked his knuckles. "You want to explain this, Ciel?"
Ciel’s voice calmly filled Rimuru’s mind. <It’s some strange power-scaling system, master. They’ve made up classifications like 2C, 1A, and such, mostly based on arbitrary definitions of dimensionality and feats from fiction.>
Rimuru blinked. "So, in short, it’s made-up nonsense?"
<Essentially, yes.>
Rimuru’s patience had run thin. The Life Rider was still babbling about Yogiri being an unstoppable force and some absurd definitions like "2C" and "1A" when Rimuru moved faster than the flow of information particles, stepping into the Life Rider’s personal space. Before he could react, Rimuru delivered a series of precise kicks each one amplified with thought acceleration. Time stretched infinitely in the Life Rider’s perception, making each blow feel like an eternity.
"You talk too much," Rimuru said as he delivered another kick, sending the Life Rider flying across the battlefield. "What the hell is even a 2C? And what’s with all this 'Anos' nonsense?"
The Life Rider, still clutching his gut in pain, tried to rant again. "You’re just a 2C at best! Yogiri would wipe the floor with you! Anos would—"
Rimuru didn’t give him a chance to finish. With a swift kick, he silenced the Life Rider again. "I don’t care about your power-scaling nonsense."
The Avengers and Justice League watched, half-amused and half-confused, as Rimuru casually dismissed the Life Rider’s ridiculous claims. Even Iron Man, normally quick with a snarky remark, just shook his head.
"Who even invited this guy?" Tony muttered under his breath, watching Rimuru stomp on the Life Rider like a pesky insect.
Cyborg was equally annoyed. "This is what we’re dealing with now? Tin cans and wannabe philosophers? I miss the days when we just punched aliens."
Flash, still zipping around, chimed in. "It’s fine, Cyborg. This is still less weird than that time we fought mind-controlled dolphins."
Meanwhile, Thor was still trying to wrap his head around the Life Rider’s logic. "So... if a 2D being sees itself as 3D, that means we’re infinite dimensions to them? Isn’t this just basic kindergarten knowledge?"
Rimuru rolled his eyes. "Yeah, Thor. It’s all based on perspective. It’s not rocket science."
The Life Rider, now utterly defeated and humiliated, tried to crawl away, still muttering about power levels and fictional rankings. Rimuru gave him one last kick for good measure.
"Your brain rot is contagious," Rimuru said flatly. "Now, get lost before I erase you from existence."
As the Life Rider vanished into the distance, probably to monologue somewhere else, Ultron finally made his move. With all the Infinity Stones at his disposal, he attacked the city directly, sending waves of energy cascading through reality.
"Looks like the real fun’s about to start," Iron Man said, prepping his suit for battle. "This guy’s packing all the stones. We’ll need a solid plan to take him down."
Rimuru, cracking his knuckles, grinned. "Leave it to me. I’ll handle Ultron. You guys just keep his tin soldiers busy."
Thor, still annoyed at Iron Man, added, "And Stark ..no more robots."
Iron Man groaned. "For the last time, it’s not my Ultron!"
With Rimuru leading the charge, the heroes prepared for the ultimate showdown. And while Ultron may have had the stones, Rimuru was ready to show him why messing with other realities wasn’t such a good idea.
