Explanation for clone usage for chakra development

1st sorry needed to Slow down story for real life stuff and research. I think there would not be that much changes until the next movie shows up so will things will start speeding up

but there are just some years where everything seems to be happeningjavascript:;

like 86-89.

Reasons for not using other stuff to develop chakra(for now)

Based on MCU with logical background(hopefully logical)

------

Extremis

still needs development. To map bio-electricity in order to harness it, you need equipment that can keep up. Tony can build it but it would take up a lot of space ,test subjects and time.

Also need the biological process simulations before testing. Those need a Quantum Computer and not just Super Computers.

Even real life latest Super Computers still not capable of accurately simulating most chemical molecules

Quantum computer still needs way too much tech from the future that it is a VERY BIG security risk. I can't exactly miniaturize it with Pym Particles since it will probably affect quantum stuff. Just enlarging things would be possible. So no way to hide. Imagine aliens knowing there is a human made quantum computer in that primitive world. Earth cannot protect itself yet.

JARVIS during Iron Man 3 was powered by Quantum computer since the visual simulation of JARVIS and Ultron were not just some basic stuff. Mapping a brain with complete simulation is hard enough even for Super computers.

AI's would have probably already be running the world properly if they are powered by Completed Quantum computers IRL due to the amount of simulations it can do.

(AN: Simplifying quantum computers feels weird and I am not sure I am completely correct)

Also

Extremis regenerates the body at the current state

- not sure what it does to a growing human body other than BOOM

-- does it stop the human from aging or something? that's just sad to always be a kid so at least will happen in his 20's

TLDR:

Quantum Computer not yet built so no way to safely test without human test subject

---------------------

Super Soldier Serum

- Still no proper Secured Secret Base other than Wakanda. And Wakanda was just supposed to give him Vibranium + tech until T'Chala and shuri gets born. Also Wakanda still has the traitor problem.

Primarily. very volatile. (Hulk and Abomination are failed outcomes of SSS) so needs a very secure space to complete the transformation. Which is hard when it is peaceful times and espionage is the primary focus of everyone.

2nd Never trust the enemy completely or some humans for that matter

-Zola may be under control but the living agents is a different matter. They are the human factors that need to be gone.

-Unfortunately, Humans don't care.(Humans cannot be fully controlled, unless it is of their "own free will") Hail Hydra haha

-- Winter Soldier should already be active so any rouge HYDRA with control over him might mess the process up.

3rd. Can use a space shuttle for completely isolated space and building one is easy but procurement with the amount of materials used would be hard to conceal .

It needs to be done in short amount of time without Hydra's connection for maximum secrecy.

There was still no internet and too early for full automation of stuff so things still had humans in the transactions. One way or another, someone will notice metals and other stuff being ordered at large quantities. One random gossip and Winter Soldier might be sent for recon

4th miniturizing before operation may cause some side effects since Ant-Man technology has harmfull effects even to Hank Pym later on.

TLDR:

Basically no environment safe enough to undergo process yet

------------------

Arc reactors to chakra stuff

1st of all, They are NOT for everything.

Howard designed it to produce electrical energy. Sure they might be able produce almost unlimited energy but still in the range of electrictrical + light + magnetic. Still need something to convert it to biological/chemical which is usually only through food.

I can use it for assistance but not still not yet available as a direct chakra source.

Plenty of stuff from electricity but converting it to biological energy/magic energy is not something sorcerers seems to be focused on.

Electricity -> Magic -> electricity might work like Yoda absorbing electricity from the force. But he may still get shocked from those electric coated weapons if he ever got hit.

TLDR:

No direct transformation available.

--------------

Magic

-needs to be learned but later

-can be used to outsource the energy but will work differently since chakra is a personal type of energy. You can collect it from surrounding but you still convert it to your own.

-Since sorcerers are depicted as humans who channel energy from another dimension through their body. At Best, it will be is like nature chakra.

TLDR: Nature chakra equivalent not internal chakra

--------

There are some possible ways though that I was preparing to use later on but I won't be adding them here since it might spoil more than necessary
