Kryptonian genes are technologically locked; if others research them, it's easy to create Doomsday.
One could even say Doomsday is a protective measure for Kryptonian genes: the speed of super-adaptive evolution plus an indestructible body equals the embodiment of destruction!
This is enough to destroy any enemy attempting to research Kryptonian genes.
As for how Alex can clone... that can only be attributed to plot necessity.
Alex had no interest in the Marvel plot; his mind was entirely focused on researching himself to achieve breakthroughs.
At the very least, if he could gain Doomsday's super-adaptive evolution ability, he wouldn't fear any enemy.
Unfortunately, these Doomsdays are just ordinary Doomsdays, not the truly indestructible Ancient Doomsday; they can still be killed.
Through his hypnotically controlled Military and Department of Defense connections, Alex obtained various high-precision instruments.
Even with his Super Brain and super vision assisting him, Alex still needed these instruments for operations like cultivating Kryptonian cells.
In addition, Alex also acquired a large amount of valuable knowledge and technical blueprints.
These were originally sealed World War II black technology blueprints, belonging to 'theoretical science' that humanity has yet to achieve.
"It's a pity, if I had a Kryptonian spaceship, I wouldn't need to start from Zero like this, not knowing when I'll break through Zero and reach 1."
Alex worked day and night... he didn't need to eat anyway; just basking in the Sun was enough.
He tirelessly researched Kryptonian genes and cells, and studied.
With the help of his Super Brain, Alex spent less than an hour learning all of humanity's knowledge in genetics, and he also completed programming studies, creating his own artificial intelligence.
"Megatron, how are the samples?"
Alex asked his artificial intelligence.
"BOSS, all ten thousand samples are currently reacting normally, with no abnormalities detected,"
Megatron said calmly.
"...Destroy all samples and cultivate new ones."
Alex rubbed his forehead; why did it fail? If the reaction was normal, then it was a failure.
What he wanted now was to get some Doomsday cells out and study Doomsday cells!
Therefore, normal cells held no meaning for him.
Megatron strictly carried out Alex's command, inactivating and completely destroying all Kryptonian cells.
Kryptonian cells have extremely strong vitality and survival capability; unless the Kryptonian himself experiences mental death, they can revive just by basking in the Sun.
However, that doesn't mean they can't be completely destroyed; if the power is sufficient, anything can be destroyed.
Alex sighed, enjoying the sunlight.
The energy in his cells was also fully replenished.
Then Alex's brow furrowed; he had awakened a new superpower!
This was not surprising; even if Alex had awakened all of Superman's movie-version abilities, it didn't mean he wouldn't awaken other superpowers.
After all, even the Universe was different now; who knew what the Kryptonian laws were like here.
Alex's brow furrowed because this meant the appearance of an uncontrollable variable.
All the Kryptonian rules and information he knew might be overturned.
"The ability is... teleportation?"
Alex's eyes widened; teleportation?
Teleport to where?
Is it like Super Kryptonian H'el, who can travel through time to the past or change the future?
Or is it the kind of teleportation he knows?
If so, where would he teleport to, the DC Universe?
Could he return after teleporting?
Alex knew none of this; the uncertainty of this superpower was too great.
"It shouldn't be World teleportation, right? My current energy and magnitude shouldn't be able to support the power of World teleportation... at least not until I'm single-Universe level and Skyfather level, right?"
Alex scratched his head, deep in thought.
However, he was very curious.
So curious it was almost unbearable.
"Let's try it; it's better to find out than to keep wondering about it; otherwise, I won't be able to concentrate on my research."
Alex made up his mind.
Just in case, he made himself a battle suit, with ample solar energy built-in, not for protection, but simply to allow him to replenish energy at any time.
What protection does a Kryptonian body need?
With the dual protection of Steel Body and Biological Field, that is the best protection.
As long as there is Sun, as long as the energy in the cells is not exhausted, then for a Kryptonian, nothing is a problem!
"Come on, teleport!"
Alex activated his superpower, and accompanied by a blender-like sensation, he felt as if he was shoved into an extremely narrow passage, his entire body squeezed to a pulp.
The powerful Kryptonian Steel Body and Biological Field were as fragile as tofu.
In an open space, with a "splat," a pile of minced meat appeared out of thin air and fell to the ground.
After the warm, bright sunlight shone on the minced meat, a bizarre thing happened: a skeletal hand emerged from the minced meat!
