Invincible SI: Actually Invincible

It sucks that of the two Invincible Self Insert fanfictions I have found, neither reliably updates. So here I am to fix that by bringing the world an Invincible Self Insert fanfiction by an author with a proven track record of reliable updates, finished stories, and the full capacity to play with the plot however I want without twisting the traits and tone of the characters. So strap in for a good time. Fair warning, the SCI-FI will be harder than what is seen in the comics and TV show and some of the plot conveniences that get thrown out as soon as they are introduced are gone. Props to LordValmar for the cover image Massive props to SeekingRaven for funding this story. U da best, Dawg.

Rejoice

Kate proved to be a woman of surprising depth and welcome flexibility. Both combined wonderfully with her capacity to fight my raw reach and endurance with a never ending horde of the fresh female fuck flesh of her duplicates. Eventually we simple agreed to a draw as she reabsorbed the mountain of of pleasure induced coma clones and we settled down into a more…sedate threesome.

What happened next was not vigorous, athletic, or acrobatic. I wasn't trying to impress my superiority so deeply into her core that it permanently scars her subconscious and ruins sex to the very conceptual level with lesser partners. It was basically girl porn fucking until the three of us chose to stop and just cuddle with a Kate resting on each of my massive shoulders.

"What are you thinking about?" asked the one on my left as she traced the striations of my chest with her index finger.

"I am glad your tits are so big." I answered about my incredible joy that she didn't get the TV show breast reduction.

Dupli-Kate deserves her big sexy tits. She knows damn well how to use them.

"That's… it?" she grimaced.

"In the endless subset of realities, we could live in a universe where you have small tits and I am a fuck up." I sighed.

"O…kay…" she shook her head.

Kate had me fly her to the Teen Team headquarters, a multistory office building on the shore of Lake Michigan. We entered through a hidden vertical take off trap door revealing the hollow guts of the building who's façade hid the comings and goings of the super team.

We found Rex Splode playing Ping-Pong against the folded up table and when he saw us he caught the ball and slammed it and the paddle loudly down.

"Dupli-Kate and Invincible, welcome to our formerly secret clubhouse. I'm so glad you unilaterally brought your new boyfriend who we know next to nothing about." Rex shouted.

"Unilaterally. So you can learn." Kate sniped at her high strung team mate, "And Eve knows about him. Didn't she say she'd recognize his ass anywhere?"

"Don't remind me." Rex muttered.

"Thank you for bringing Invincible here, Kate." Robot stated as he emerged from another room, "I've made an early warning system in case of further incursion from the Flaxan dimension and the GDA has asked us to stand ready in the… absence... of the Guardians of the Globe. We truly need your aid for this, Invincible."

"I'd be happy to help, Robot." I nodded to the automaton, "Do you know why they began aging so rapidly yesterday?"

"Yes I did." Robot answered, "Time functions differently in our dimension and theirs. From what I can calculate, they experience three and a third years for every day that passes in our dimension. But this effect is greatly exacerbated on living matter, accelerating the aging process catastrophically."

"So they have already had almost three years to figure out what went wrong and train up new soldiers to replace their losses." I grumbled like I didn't already know that.

"Exactly." Robot agreed, "A species that has figured out interdimensional travel likely has the capacity to invent a method to counteract the effects of the differential time streams."

"Then we should hope that they are the kind of species that doesn't like hitting resistance." I told them.

"Unfortunately this is not the case." Robot denied, "My linguistic analysis translated much of what was said during the battle. The Flaxans are a warrior race and will return to fight us as many times as they need to win."

"Just great!" Rex sploded, "As if all the lasers and explosions and screams weren't enough yesterday."

I took out my notepad and pen from my utility belt and jotted down an address for Robot, "If you can send your translation to this address I'll get to studying it. It's so rare to find a species that speaks anything but English."

"What's he talking about?" Rex questioned.

"Most alien species speak English." Robot confirmed.

"WHAT? Why?" Rex shouted in shock.

"I figure English is the language of the gods and everyone not speaking it are heretics." I patted the jumpy fucker on the shoulder.

"Oh hey, I didn't see you at school today." Eve greeted as she floated down from the roof using her pink energy discharges.

"Yeah. I dropped out." I answered, causing the girl to pull a shocked face.

"What? Why?" she demanded much like Rex.

"I told my mom I'd stop pretending to be human when I turned eighteen." I informed her, "She got to enjoy a normalish parenting experience and I didn't have to have too many uncomfortable dinners growing up. But that's over now."

"Oh… well, congratulations on finally getting to be yourself." Eve awkwardly stated.

"Thanks Eve. I appreciate the sentiment." I smiled at her.

"So wait, you're hooking up with an alien? Gross." Rex fake barked at Kate.

"He's the best lover I've ever had." Kate snapped back with a pointed look at Rex.

"Oh really!" Rex shouted back.

"What the fuck am I seeing right now?" Eve broke up their pissing contest, causing Kate to smirk.

"Rex?" Eve demanded in his face.

"Nothing." Rex muttered and looked down at his feet.

"Doesn't look like nothing." Eve growled.

"You want to get out of here and get something to eat?" Kate suggested as we watched Rex and Eve implode.

"I'm thinking Italian." I smiled at her, "Ever been to Calabria?"

--------------------------------------------------------------------------------------------------------------

"Marry me." Kate commanded after she bit into her late night dinner plate of macaroni with pork, eggplant, and salted ricotta.

"It blows my mind that one of the most beautiful regions in the world is also one of the poorest regions in this struggling country." I stated as I looked out over the Ionian Sea from our clifftop restaurant, "I hate watching people fall through the cracks, history disappears, culture dies out. This world is so easy to fix, but it fights tooth and nail to stay broken."

"I didn't take you as a big picture type of hero." Kate sighed in disappointment.

"The big picture is just a collage of all the little pictures put together." I explained, "If you keep sacrificing the little things in the name of the big picture eventually it doesn't matter anymore if the big picture is there or not because it is just a warped and rotting wreck."

"I like the way that sounds." Kate nodded her head, "Every little bit matters even when it seems like nothing ever gets better no matter how much good we do."

"I like you Kate," I told her after taking a sip of my Aperol Spritz, "But I'm not letting the Flaxan's get a third shot at enslaving this world. If they try again I won't be fighting to stem the tide, I'm going to the other side to stop them, no matter how long that takes."

"I see." she sighed.

We ate the rest of the meal in silence.

--------------------------------------------------------------------------------------------------------------

We got three whole days between the first invasion and the second, in which I brushed up on Robot's translations, but I would be relying mostly on Viltrumite Telepathy tech for the bulk of communication.

Kate and I continued our satisfying affair as we waited for the world to get invaded and when the call came I wasted no time at all annihilating the enemy vanguard, plowing through their soldiers and tanks faster than a bullet.

I grinned as I landed in front of the enemy leader, an elderly Flaxan with burn and shrapnel scars over half his face in a fur trimmed red cape.

"This is not your world to conquer." I communicated aloud because it felt right and eased the process of communicating directly with his mind as I grabbed the top of his chest plate and dragged him back with me through the portal.

We arrived to see the next company of soldiers in formation to march through the portal.

"Rejoice." I told the assembled Flaxan Army as they received the message mentally and I slowly took the master portal device of the belt of their leader and shut down the connection to Earth, "For today is the day that the Flaxan race joins the Viltrumite Empire. Many of you will resist, and for that I am grateful. I will use your blood and broken bodies as mortar with which to rebuild the wreckage of your nation into a dutiful servant to the glory of Viltrum."

"Mark?" I heard heard from behind me.

I turned to see Kate standing there clutching her head. She screamed as the six on her chest dropped to zero and fell unconscious.

"Well… shit." I sighed.

I actually started writing this chapter late last night yesterday after I posted chapter 3 and when I was reading it through today I was like, 'Dafuq was I thinking' so I ended up rewriting most of the first scene, the second scene seemed good though.

It was wierd how bad the first part was, because I feel so fucking exhausted today, way more tired than I was last night, but I guess God stopped me so I could sleep on it and not release a steaming turn of a chapter.

I think I figured out the best use for the Flaxan Dimension, so get hyped for the what comes next.
