Reincarnate story similar to dcmcu: kaiju system by wiz161 but focused on the monster hunter series our main character is able to use only the monsters from the Monster Hunter series as Transformations that can level up and evolve  just like in the Kaiju system story another fanfic that is similar to my idea is My monster hunter academia (monster hunter X my hero academia) by Raptorix though the story hasn't been updated for over 3 years, but my idea is a multiversal travel story though, our main character gets the Monster Hunter system he starts off just like in Monster Hunter with access to all of the weapon types but only their base grade just like how you start in Monster Hunter but unlike them he's able to switch between them on the Fly so one second he can be using the sword and shield the next second he's swinging at you with the Greatsword he also has access to all the equipment that you're able to use in Monster Hunter world and Monster Hunter rise so he has the scout flies, the slinger as well as the wire bugs from Monster Hunter rise for allies he will have at the start and will always travel with him will be two palicos so he can use the techniques from all the monster hunter games like the 3ds game monster hunter 4 ultimate like the cats rocket and the little tank they can get but he has to unlock them through special missions or purchasing them through the store or something like that the cats will also have the abilities in Monster Hunter world but for all of these you will have to purchase the equipment for them as well so they can use the techniques or unlock them, at first they'll just have basic equipment so all they can do is just help them like normal he will also have the palamute from Monster Hunter rise as well as the cahoot to help for tracking monsters and people as well as being able to help you later in combat once you purchase skills or unlock abilities for it but the scout flies will help in dense areas where the cahoot cannot help, the system will be similar to the Kaiju system like the missions it give will be random but they'll also be permanent missions that have to do with monsters that are present in the worlds that he goes to his starter world will be danmachi where he'll stay fo a little bit and get used to his abilities since that world's kind of like a decent tutorial world I believe it feels like one where he can be an adventurer to train his abilities by hunting in the dungeon before going off to other worlds for Missions as well as exploration or it can be his main hub where any allies he makes in danmachi and any other world can join in his adventures, an example for the permanent missions would be constantly killing let's say 30 goblins every time he kills 30 goblins he'll get a bonus amount of EXP as well as money and maybe a little low level loot box obviously once he gets further up in levels this mission will give too little exp for what he needs and then for every new monster he slays there will be a new permanent mission for that monster and they're also be missions pertaining to the stories of the world that he goes to or other things he comes across the World Travel won't be just one and done he will travel to that world stick around for a while gain strength gain items each new world he'll go to unlock new items that he can purchase like if he travels from the world of danmachi to marvel he can then purchase modern weaponry or items from the Marvel Universe if you had a ton of shop points you could purchase the Infinity Stones some items in the shop can be bought with shop points some items can be bought with the gold or money he received from the system he can also Exchange money from the current world he's in into shop money but the money he has can only be used to buy equipment like weapons, armor, vehicles but anything that has to do with largely increasing his strength will have to be bought with shop points which can only be received through missions or loot boxes so as not to give him easy access to God tier crap to easily. So he can get loot boxes from Mission Rewards, use shop points in the store for random gacha or from new monsters. skills can be learned through doing it, bought in store, rewarded from Missions and loot boxes and then leveled up with skill points which can be earned through leveling up and Mission Rewards and random chance in loot boxes, money and equipment can be received from missions enemies and loot boxes for every new monster he slays he'll get an initial bonus exp money and a equivalent loot box to how strong the monster was or enemy captured the captured rule will apply to the world's like the DC Universe and Marvel Universe since killing is bad in those universes in certain cases like for human Crooks or sentient beings it's fine. If he goes to Worlds where it's okay to kill people like Bandits if he goes to Medieval World like swords and magic and stuff like that I would also like him to travel to Worlds like besides the DC Universe and Marvel Universe to travel to different anime universes his first other world mission will be High School of the Dead where he can train his skills against low level zombies that way he can up his skill level as well as gain access to modern day equipment like vehicles and a couple allies as well like the gun nut Kohta Hirano with his knowledge of weapons and military training would make for a great back liner the sword user Saeko Busujima with her high level combat skills as a front liner as these 2 would probably thrive in danmachi then gain enough strength for other worlds and the other protagonists as well like Rei Miyamoto with her spear skills would make for a good front liner, Saya Takagi would make for a decent strategist as well as a mage if she awakens it with a falna, Shizuka Marikawa for her medical knowledge and probable awakening as a healer with a falna and her friend Rika Minami for her sniper skills for scouting and as a back line attacker, and Takashi Komuro for his well rounded melee and shooting skills and his leadership abilities would make for a great vice captain who can lead the group while the Mc goes to other worlds with or without other people Asami Nakaoka I would also like to save she could become a combatant or non combatant, Alice Maresato would also be saved with her father and zeke they would join the group in danmachi as non combatants with the characters families and other survivors except for the bad ones you know them if you research joining as well to get away from the zombies and will help with Familia stores or other things our main character can help them join a decent familia like Hestia, Loki, Hephaestus or any of the other decent ones to help them get on their feet and learn how to deal with the dungeon to get them started he can then go off on other Adventures or stick around for a bit until some of the people of the group who wish to join him are strong enough to join him and go to other worlds other allies that will probably join him at the start

Can be Bell and his Familia and the Loki Familia, our main character will kind of create a hunter's Guild where the hunter system can influence things it'll mostly be him who has full access but he can also give other people controlled access to the store like certain weapons, gear and items as well as access to world travel quests if he wants to that way he doesn't have to always be with the group they can take on Quests similar to how Monster Hunter does and they can travel to low level worlds to hunt specific monsters or find specific items it'll be same in this sense, where his allies or people he deems trustworthy go on short missions where they go and hunt down certain things or go find certain items in specific locations similar to how monster hunter does it random missions created by the system or created by other worldly beings who knows allies can go and complete the quests in which they can gain strength to help the MC in the future or make there life easier in Danmachi and anything they catch hunt or gather that's not part of the mission requirement they can keep so like Hephaestus can help the hunters Guild and sate her blacksmith blood with new materials and such but most of the things that pertain to the hunters guild will be Side Stories the main focus will be the main character and other characters that join him in his adventures

This way we can add some flavor to his journeys different allies at different times joining the fights allies will be able to stay in there world and still have access to the hunters guild and have the ability to move between worlds that the mc has established a hunters guild in or for reasons like if the world is apocalyptic like High School of the Dead they would leave and go to a different world like mc main base of danmachi or other worlds to live and take quests if they want to. Starter world will be danmachi next High School of the Dead sticks around until near the end to get the before mentioned characters other anime world's will be mostly other monster and magic worlds to slowly gain new items strength and skills like the anime "knights & magic" for possible Guild allies and the Silhouette knights tech i would like for our mc to go to certain worlds like one piece he can stay for the whole story helping luffy from the start of his journey to the end or at least upto a certain point, or just a mission that sends him to one piece for The Summit War of Marineford where mc helps to save Ace and Whitebeard but thats just what i want and it would give the store devil fruits. Most items and gear that will be available through these worlds like the devil fruits, weapons and other combat items like grenades will mostly be used by his allies our main character will stick with the equipment and items from Monster Hunter and his monster transformations and skills but depending on the world he goes to so as to not stand out to much like if he goes to RWBY he would try to limit his powers and fake that its a semblance and focus on monsters who have similar abilities like the Lagiacrus and Zinogre with their lightning abilities as a form of training unless its necessary to use his full powers so he can join the story and help the characters grow and keep them alive like Pyrrha Nikos only using enough strength to change the story then after salem he will reveal himself and the allies he might have brought and ask the characters of RWBY if they want to join him as allies to his hunters guild. He would also purchase vehicles to travel around like if he doesn't want to walk all the way to a town far away he can purchase a motorcycle or car depending and a boat to travel the seas depending on the vehicle the system will modify it so he can operate it solo and will impart the knowledge about the vehicle like what the specs are how to use the weapons if it comes with weapons as well as just how to operate said vehicle so if he's never flown a plane the system will give him the knowledge so he can fly it and can maybe turn into a skill it'll also be the same if he has any allies with them the Allies will choose certain stations that must be manned and will gain more specific knowledge to help them do it
