Batman

Oh god this is gonna be a long one, why you may be asking? Because batman is quite possibly the oldest villain to debut in ze rp aside from thanos and other OG's. For the sake of not losing 50 years of my life i will mainly summarize main events he's taken place in and how he's changed as time goes on while of course adding in the occasionally gag moment which contributes to his character as well.
Batman started by simply fighting heroes in the beginnings era around his debut time, he'd jump at people and yell, "NAIR." Despite being a villain though his relationship with classic was seemingly up and down as at (10/21/2021) classic talked to batman about how inklings wanted his dong, where batman responded with, "don't blame them lmao," then they parted ways. Though he did haunt classic and ink a day later making them almost lose their minds (i presume batman was dead but to be honest even i don't know what was going on in the beginnings era.) 
Moving on from that, batman has participated in like every huge event ever, specifically the gacha wars in which he often aided classic and the heroes before going back to his usual schemes. There was a strange time at (01/28/2022) where spy tf2 was tryna buttsecks meggy and batman was tryna stop him (like i said, OG batman was not all that bad sometimes.) On that same day batman convinced meggy that classic was a villain as batman continued attacking classic and meggy. Meggy came up with some dumb equation classic=badguy=jerry, because meggy is a retard, regardless she kicked classic out of the house and classic just kept fighting in the gacha war. 
Goddamnit i'm already getting sick of how much documented shit batman does, right... so batman has a lot of super suits that he designed himself to take on many heroes like at (02/10/2022) where he fought miley in a gacha war i believe, and apparently classic was helping the villains at the time to kill meggy and her kids (he was bipolar in the old days.) 
Fast forwarding a lot to 06/16/2022 batman usually harassed natsuki and kale until natsuki "bit off batmans dick while saying, fuck you, batman!" She did this because batman suggested kale x ella as a good ship, (typical natsuki.) Regardless, after that batman let out an "old man scream," then presumably died. Batmans also worked with quan and other villains to fight koby and chara a couple times (its failed every time.) Batman also somehow found his way into laqnesh to attack natsuki (06/19/2022) then was killed by kale. How did batman travel through to a completely hidden universe? Well probably due to the random nature of the villains, sometimes allowing them to bypass plot points. 
That same day batman... killed thugs who were going to rape an old women. Ah yes, this is where koby began to control the villains (despite supposedly being weak at that time.) Next at (07/01/2022) batman came outa nowhere and broke a rock over hu's head as she and kale were banging due to a love potion. Kale proceeded to, "break batman and fucking slaughter him," (simp.) Batman did try to distract him with pics of hu naked but it failed and he died. Despite dying it seems batman killed hu as well, after kale revived hu tao, batman apparenlty, "was alive," and snapped hu tao in half. Kale then threatened batman with dying forever like classic was at the time, batman then just made hu suck kales cock however kale kicked batman off the building then allowed it. The next day koby and batman worked together to kill angel as she bullied ella and was being a bitch. 
Jesus there's so much documentations i mean uh, right, so, at (07/10/2022) batman analyzed a crime scene and made the deduction that james had kidnapped chara after angels death because he's a piss baby. Of course batman was right, (he is the worlds greatest detective after all.) Batman also unsurprisingly was able to lead the heroes to james exact location within a short timespan. Batman also arrived after james had shot koby in the head and chara had died, he had joker heal kale to the best of his abilities. Batman also talked about how chara was a half demon so she couldn't actually go to heaven and yeah... they went through a bunch of stuff like that.
...You're still here? You must really like batman, or you just wanna hear what happens next, fine, i'll heed the demands. (07/17/2022) batman tries to hold ganyu hostage, but koby has golden freddy's giant floating head crush him. A day later at 8:16pm, batman grabbed caleb and threw him into keqing's titties. Keqing sidestepped caleb and said, "didn't think you needed help, hehe~" Caleb pulled himself to his feet and responded, "hey, i don't need help, i'm fi-" batman had bashed caleb, interrupting the sentence. This must've pissed caleb off though, as he then kicked the shit outa batman somehow.
Then at (08/02/2022) batman dropped down beside peter who was recording koby and ganyu fucking, sadly the moaning was too loud and uhh killed batman somehow (don't ask me bro.) Not like it matters anyways, as minutes later batman fought and killed squidward who was acting crazy towards kale, squidward tried to shove a spear up batmans ass, but batman dodged and used martial arts to subdue and dispose of the tentacled menace. Batman then went on to rape and assault some locals... why? i have no idea. 
2 days later nukemaster attacked and batman decided to assist classic and the heroes although kale stated it was pointless and they would all die. After some drama with kale dying due to koby's stupidity and coming to terms with stuff, batman approached kale and said, "the villains have agreed to help... the enemy of our enemy is our friend..." This was probably one of the most epic moments of ze rp, the heroes and villains teaming up to fight nukemaster for the first time, during the fight batman helped take down ganyu who had become nothing more than a pawn of nukemaster. Batman stopped ganyu from manipulating koby and proved to be far stronger than usual (likely due to the collaboration happening in the moment.) After the heroes won the fight, batman announced that the villains would return to their normal behavior soon, but would keep it to a minimum as he said himself, "the villains serve a purpose, whether that purpose is stupid in terms of common sense or not is irrelevant, fighting the heroes is our thing period, but i think most of us now understand each other better." 
Batman has made many more appearances in ze rp after that major event and continues to be a OG villain who's been alive since the very beginning. Despite all the documentation that as ze rp progresses i think all the stuff that has been laid here is more than enough to understand the dark knight, and his role in the story.
