[Western Crossover] Lex Luthor Kicks the Plot to the Curb

This is... a very complicated world. Basically, all kinds of movies, comics, TV shows, and games have been mashed together to create it. It's the magnum opus of a “World Forger” who loves making fanworks, though it's falling apart. In a panic, the World Forger tries to save this harmless little hobby one more time. So some unlucky guy is chosen to become the world's only hope, though he has no idea. All he knows is that he's been reborn into a world full of all sorts of gods and monsters. There are superheroes, aliens, and local gods... And he's also the exclusive nemesis of a certain alien superhero. Lex stares at his childhood friend. “You? Me? Nemeses? Seriously? I'm supposed to fight Superman?” Clark is even more distraught. “Who? Me? You're my nemesis? Seriously? I'm supposed to fight Lex?! How am I not going to get killed without even realizing it?!” At this moment, they are standing on ground that could be called Lex's city. As far as the eye can see, or rather, as far as Superman can see, LuthorCorp's businesses spread and cover the area. Luthor's tentacles reach every corner of the world, whether or not someone else has already claimed it. This is Lex without Superman to occupy his attention. This is Lex, the transmigrator with both parents alive. So he really is powerful. Superman still has one hand pressed against the assassin's hidden blade, but doesn't take the assassin seriously at all. He's still arguing with Lex about which of them would make the more terrifying and outrageous enemy. Sweat slowly runs down the assassin's temple. He knows he may not make it out alive today, but they knew this could be the outcome the moment they set out on this path. What surprises him is that Superman would side with the Templars. Lex at three and Clark at five argue for ages, until our esteemed secretary hero, Caroline, wearing a “Mercy” name tag, bonks each of them on the head and drags them back to the point. “Boss, if you don't pay attention to this guest, LuthorCorp is going to be branded with the Templar label. Some of the chuunibyou types in the company might not mind, but please give me less work. You don't want to see the integrated industrial park attacked a second time, do you?” Lex's eyes instantly clear, and he shakes his head furiously. Superman shudders and shakes his head like a fan, too. Assassin: “? We don't attack places where we could cause large-scale damage! That's a slander! An absolute slander!” The second Lex story explores the possibility of Lex transmigrating into an ordinary DC-Marvel crossover world (is it really ordinary?), featuring DC, Marvel, Assassin's Creed (staying true to the roots), Watchdogs (here I go again)... Mainly DC and Assassin's Creed. This idea came about because I really wanted to write one particular scene. Lex sees an Assassin kill everyone in their way whom they consider guilty, and, don't ask why the Templars are the enemy, just know they're getting killed (especially in the modern-day storyline): “That's insane.” Then he turns and sees the Templars: “Fine, you're insane, too.” Theme: Walk the path I choose, and sing as I go.
