Make a grupe, and they can help, brainstrom you know, and leave the name of the grupe to join in...

That why is better to only take out tech 3 to 5 years ahead its times puplic and the rest of the tech for himself, also tech for food production or agricultur is a good choice, after all hunger problems is always a problem in the world

All actors

Just like act in the abbys paths there are 2 way evil and enjoy it or the necesary evil the you do it cause the world need sometime someone to take the blame, also there is another way for acting without killing for example making people belive that you are a killler but never have kill someone is a type of acting, or taking creding for killing someone when it was someone else how did it is another way of acting, without killing.

He need scv from starcraft to build things faster... or a robot assisstens for tinkering.

How about a "terror infinity" sistem, the same things as terror infinity but he can only control the world he can go in, he has a month to prepare or can go before if he wants and he is the only player, but can add more people if he want, and can lower the difficult only by 20%.

Yes, he is from the foundation, but this might be a way to put the blame on shield or something like that.

SCP-914 - The Clockworks, can be use to create weapons or raw material at the level or close to vibranio, even the iron man armour mark 1 can becamon mark 50, or medicines too. The arc reactor too there are many posibilities.

The best way is only take things that are 5 years ahead the time, in that way you can keep taking new things,and taking things that make the world change to much like virtual reality is not a good idea, there is a moment to get use to that kind of change, take as example the industrial era, the changes create many conflctsand oportunities, in all it some tech need time and bring them little bit little.

Others tech he shall work in would be the ones already exist, but make them better, like phone batteries just making them 40% more store for enery every 2 years is enough and he only can make money from the patent.

Pretty sure there are some potions for increse intel... permanent, which is not as much the NZT give temporal but is good getting a permanent increse.

Folding tech, compress tech, and weight tech are important which has a similar effect like shinkring tech but more easy to get and use.

Something that he truely need might be scv from "starcraft" for construct anything, just think about it even to construct something like a nuclear plant it might take a year or so and the things he might need even long even if he has the tech and materials, another thing is an A.I. that is the most loyal, if yoy ask me "nier" has has the most loyal A.I. and the last thing is a robot that is good at research new tech like the one in "Astro Boy - 2003" the dr. That create astro boy did create a robot that make robots better than the ones he make.

If i can chose my cheat i eill chose to have a good teacher rather the a power or a system cause so.eone to guide you is very important, is you were a nomal person before, i will you Li Giye from "emperor's domination" just having him ad my teacher is better the any cheat or system, i can also better myself as a person and know what to seek.

Have you read "lord of the mysteries" it will be a good system even the focus can be build a tarot club, and a church, and make the world he is ready for when the mysterios world come.

He should buy the path of "mech touch" for mech designer so he can make his brain follow the path of more computation power, or any similar path, it will be nice that he get something for his friends that might stay as normal people, so they can protec themself, like a mecha, add the tech to hide the mecha or gundam in the void and come to you when call.

Stimpak is could sell pretty good to the miliar even food that can help the body keep its best state and build a better body is good to sell them

Something to note is that some tech material might not exist in marvel world, but others material do exist are better in some cases, if you want to build a gundam or mecha, sometime buying the tech of 1 world is not enough, sometimes is better to buy from 3 to 5 different tech about gundams and mechas, in that way not only can solve the problem of some missing material but making for the weakness of each tech and making something better and more powerful, also another way to solve the problem with material is, material scient where you can make some material in an artificial way, just like making articifial diamonds, and depending of how good this tech is even vibranio can be copy.

Making the mc look more human is a nice touch

Not just peter is the only spider man, gwen, miles moralis, even flash the bully of peter which he is a jerk bad always in times of crisis help in many comics, if you want you can give theses people another path to be a hero, and create a smurt account to help then and teach then how to protec their identidies, in that way getting many points, and killing many bird in the process, also another smurt account as a tech support for some heroes, giving then better equipe.
