He is a genetically experimented upon alien. He's not a Homo-Sapien Superior, like the Sentinels are designed to detect and adapt to based off Mystique's HSS, self-mutating DNA.
So yeah, they shouldn't be able to copy his powers or adapt to them.
On the reverse, they're vulnerable to physical damage. And his HV can really kill a lot of them at a time considering the X-Wing bomb took out a decent chunk.
What kind of thread is this... So they have no adaptive powers... So what offensive powers do they exactly have then?? Most of the finishing moves we saw were based on their foes powers and adapting. What do they have now?
To be fair if they do have adoptive powers, then it's a non-fight the other way, because then that becomes like 100 Doomsdays vs 1 Doomsday. Either way it's a silly match up.
They can do what they were designed to do. They just don't have unlimited adaptation potential. They're built and based around mutants from the FOX X-Men verse. Mystique's DNA is at the center of their creation. They can mimic mutant powers when that mutant is nearby or in contact with them. Otherwise they're just sorta durable, strong robots with Destroyer face lasers and spike arms.
And while yes, Doomsday is a mutant technically. He's a Kryptonian that was altered post-mortem in a lab. He's not homo-sapien superior that they can copy off of.
So yeah, Doomsday basically just rips them all apart and uses his HV until there's nothing but scrap metal left.
First, DD is mutant. Second, they OP never said they can't copy his powers... he didn't WANT them to be able to his power for the purposes of this thread. Hence the lame part.
If you watch the X-Men movies, you know in that universe "Mutant" is a term meaning a person with an extra genome(the X-Gene) that gives them their "mutant" powers. It's not just a broad term for someone who is mutated in any way, like having an extra toe or being altered to become Doomsday.
They explain this very clearly in pretty much all 5 main movies, and the 2 Wolverine ones.
They also make it clear in DoFP that Trask's Sentinel's use Mystique's adaptive DNA that allows her to mimic people to somehow adapt to and mimic mutant abilities.
Doomsday is not a Homo Sapien Superior(Mutant). Which is a human born with that gene that gives them their powers. He's not like Cyclops or Colossus or Nightcrawler or Mystique. He is a Kryptonian(alien) that was artificially modified in a laboratory.
This means that while he is a mutant due to being forcibly mutated in a lab, he's not a "Mutant" in the terms that are necessary for his power to be copied. He doesn't even have an X-Gene, so what would they copy from him?
OP is keeping things standard. They can't copy his powers because their tech doesn't work on him. You're trying to give them abilities they don't have.
