What are the common themes in possessive wolverine and rogue fanfiction?

TRANSMIGRATED TO WARHAMMER 40K! Lucan, once a 20-year-old gamer fed up with bad sequels, is brutally thrust into the grim darkness of the 41st Millennium! He awakens as a dying Rogue Trader heir, but with a game-changing cheat: a System that brings his game arsenal to life! Marines to mow down cultists and heretics? Summoned! Medics performing impossible battlefield miracles? Deployed! SCVs to repair a failing Warp Engine with methods that baffle even the Tech-Priests (and might just involve a 'soothing massage' for the ancient Machine Spirit)? You bet! Ambushed in the heart of his family's flagship, suspected by wary ship officers, and with Chaos cultists rampaging through the lower decks, Lucan is the last heir standing. The legendary Warrant of Trade – his birthright – is within reach, but only if he can survive the next few hours. The voidship is crippled, a mysterious plague is spreading, and the former Rogue Trader is missing, presumed dead. Lucan must: Master his unique System: Unlock new units and uncover the secrets of his newfound powers. Prove his loyalty: Navigate treacherous Imperial politics and clear his name. Save his ship: Battle Warp horrors and repair catastrophic damage before they're lost to the void forever. Claim his destiny: Rise from a near-corpse to the head of a Rogue Trader Dynasty. His knowledge of game strategy is now his greatest weapon. But in a galaxy where heresy means death and the gods of Chaos watch with hungry eyes, can one transmigrated gamer with a game arsenal army truly forge an empire amongst the stars? His toughest game has just begun, and in the 41st Millennium, it's play to win... or die trying!

Author's Note:this is my fanfic i wanted to share it with you,the latest chapters are on AO3. Link: https://archiveofourown.org/works/70376611/chapters/182804786 Logan’s claws aren’t his only weapon anymore. After the bonding of adamantium, something in his genes changed. Every time he crosses claws with another mutant or monster, his body resonates, adapts — stealing a piece of what makes them dangerous. Predator’s senses. Hunter’s reflexes. Bone-deep claws that never break. From the frozen north with Hulk and Wendigo, through the blood-soaked corridors of Department H, to the jungles of Krakoa and the nightmare of Proteus — Logan evolves, one fight at a time. Each victory brings a rush he can’t resist, and each upgrade drags him deeper into something between survival and addiction. This isn’t just Wolverine’s story of joining the X-Men. It’s the story of a man becoming something new — an equalizer a predator who can’t stop changing, and maybe the only one brutal enough to carry the world on his claws.

=== Author: gothicjedi666 === *Disclaimer* I really liked this fanfiction so I wanted to put it here for easier reading, everything belongs to the original creator. If the original creator wants to take it down, pls leave a review below. This is where I read it- https://www.fanfiction.net/s/13854108/1/Rogue-Trader-CYOA-Story-1 === Synopsis: I've been asked a few times by reviewers to do a Warhammer 40k story, but it's not a universe I wish to find myself stuck in for any length of time, so I used the Rogue Trader CYOA to come up with a setup that could lead to a ship and people from the 40k universe going to more sane dimensions thanks to a special Dark Age of Technology drive. This drive was created shortly before the AI rebellion and the Warp Storms screwed over the most advanced human civilization that the universe ever knew. It allows the captain of the ship to go anywhere he can envision using some psyker power and cool tech that messes with the Warp. The SI has psykers powers that he doesn't know much about due to Inquisition's meddling, an IOM light cruiser which might as well be unstoppable in some science fiction universes, a Guard Regiment of veteran soldiers who will obey the SI's orders and a warrant telling him that he can pretty much do as he pleases outside of the IOM. No one in the IOM will try to stop him even if they could as long as he brings back nice stuff for the forge world that supports him and cooperates with his allies. He will have to return to the 40k universe for resupply and repair work, but that risk is manageable. Due to his rank, he has a lot more leeway when it comes to dealing with aliens than most IOM humans so he doesn't need to kill all the non-humans as long as he isn't seen to get too friendly with them. He has a battle harem, but they don't have real personalities they are more like bodyguards who can also serve as eye candy. So he might as well recruit skilled females for his crew or clone them if he doesn't mind waiting. He'll also need a few wives to provide him with heirs. Rogue Traders will often gather an entourage of hangers-on and companions, and this may contain alien warriors, mutants, and other undesirables who would normally be unacceptable in polite Imperial society, as such he has options for companions. He can fight in wars, go after space pirates, destroy entire hostile Xenos races, and save humans. He can plunder whole worlds just to make a profit. He just needs to keep his coffers full and bring back some shiny stuff. Should he bring back enough to appease the forge-world and impress his allies I'll give the SI more fun toys taken from the CYOA and maybe even a more powerful starship. Can't say that I'm happy with this first couple of chapters, but they do contain a lot of information that explains who and what Rogue Traders are, as what the Imperials will do, and the story will get more entertaining I promise. Please share some ideas with me either here or on my patron where I am also Gothicjedi666. I post draft chapters on that site you might not have seen here and I don't have many supporters even though I have lots of people reading my stories. To those that do support my writing, I want to say a quick thank you.

Tyson's confusion is palpable when he wakes up disoriented in the back of a truck. But the real kicker? He's replaced the X-Men's signature hero, Rogue, and gained her superpower, a gift and curse combined. His touch becomes a danger to all, but holds near-limitless potential.

Takeo Minamoto had transmigrated. He crawled out of a grave, reborn as a boy named Kamado Takeo. Then he learned—this world has demons. And not just that... it's an anime world. One he’s never even seen before. Ugh... I scrimped and saved, just to buy a massive TV—and for what? I binge-watched Avengers, Inception, Loki, The Wolf of Wall Street, and every goddamn Nolan mind-bender out there. And now you're telling me I should've watched anime instead? Yeah—Fuck you too, God! And then... He started seeing a familiar figure in his dreams? Takeo: "Can someone explain to me why Wolverine is in my dreams? And not just any Wolverine—Old Man Logan?" Wait, are you saying… if I earn his recognition, I can gain his powers?? After realizing this, the way Takeo looked at Logan changed entirely. Old Man Logan from Logan, 2B from NieR: Automata, the Wolf from Sekiro, Hide from Nioh, who defeated Otakemaru... By gaining the approval of powerful characters from different worlds and inheriting their abilities, Takeo gradually grows into a protector strong enough to guard everything. And so... This story begins with a boy who climbed out of his own grave.

What if Petunia saw the truth—and chose to raise a warrior, not a victim? When Petunia Dursley puts bitterness aside and opens her eyes, Harry Potter grows up not in a cupboard, but with knowledge, power, and a healthy dose of skepticism. No blind loyalty. No hero worship. Just a boy raised to see through the lies. As another child takes the spotlight as the “Boy Who Lived,” Harry watches from the shadows—learning, planning, waiting. And when the time comes, he won’t follow the path laid out for him. Because this Harry doesn’t serve the greater good—he is the darkness that will swallow it.
