The fact that we humans obtain viruses from other animals is very true, but its honestly not the best justification for us contracting alien viruses and vice-versa. The fact we contract viral diseases from other animals is because of a simple logical reason, because both humans and other animals have evolved in the same eccological plane, so viruses have evolved to affect the creatures that exist around them. More so, other animals are naturally much more closely related to us than other creatures, and ideally, more related to us than aliens. We naturally share a bunch of pathogens and diseases with animals like chimps, more than we do with less related dogs, and we share even less with birds, and even less with fish, and even less with jellyfish, and even less with plants. In theory, aliens would be the organisms that would be least prone to be anywhere affected by an Earth pathogen, even if they show themselves some amazing convergent traits with Earth life, in this case humans. The thing is, they evolved in a completely different environment and Earth viruses have evolved to affect native life, rather than aliens with a completely different biological composition, be it biochemical, metabolical, cellular, etc.
There is obviously lots of leeways, such as Thanos, being so convergent to humans, could have evolved amazingly convergent immune systems, so much that Earth virus just so happen to be formatted to affect Thanos. That would just imply a lot of luck. Another easier way for it to work, would be to assume Thanos, for some reason, is closely related to humans, or shares a relevant and recent common ancestor, so to allow a virus from Earth to somewhat affect him.
Another thing to remember is if Thanos has the infinity stones (Especially the mind and soul stone) he could pretty much counter Kilgraves mind control powers. The mind stone can also be used to mind control although I know he got the mind stone last in the movie.
Soul Stone able to do mind control? I do not recall anything that would indicate that.
Miguel Evaristo, I see where you're coming from. However, we have seen that aliens and humans can contract at least one virus in common, the Chitauri virus that Simmons gets. While Thanos isn't a Chitauri, he is even more biologically close to humans. Titans appear to reproduce sexually, have closed circulatory systems (given he bleeds), are intelligent, and seem to spend longer in development of features than Chitauri. If a virus can go from a Chitauri to a human, I feel confident the same can be said about Titans.
The thing is that Thanos is also much, much stronger than humans. Who's to say the same thing can't be said for his immune system?
Immune systems aren't determined based on strength. Assuming the inner workings are similar (he bleeds the same we do and seemingly reproduces similarly), then the immune system would need to have gotten and fought off a previous version of the virus in order for it to work. Is it possible that Kilgrave's virus wouldn't work as strongly on Thanos as it would on us, the same way the common cold is less deadly now than it used to be? Absolutely. However, he would still be affected, the same way we still show symptoms when we get the cold.
@Mdsb759 well the soul stone can be used to control souls and essentially manipulate anyone with a soul.
Its certainly a good counter-argument the Chitauri virus, as I have mentioned. Though the Chitauri virus might be genetically engineered specifically to be able to affect humans, while Kilgrave's virus wasn't formatted to affect alien beings, and probably nothing really outside of a human being. The Chitauri virus is also completely peculiar, in the sense it infects the host through electrostatic fields, which should be a method of transmission much more universal than relying on biological matching. Maybe I am overlooking some aspects that may not help corroborate this, but at least there's one proper point to consider. However, I do recognize that there really isn't any indication the Chitauri virus was created for that effect, and it probably only affects humans because they have been evolutionarily unperfected to withstand electrostatic shocks caused by the viral infection.
The virus of Kilgrave is constantly released into the air, and inhaled by surrounding people, up until he gives a command. In theory, if he was around Thanos, he should be able to give him a command. Although there is a point to be made on Thanos being very strong. He is virtually immortal, like an Asgardian, more properly, he ages slowly, most likely. This most certainly should indicate that Thanos must have an immensely powerful immune system, so the Kilgrave virus would probably have a lot of trouble infecting him. Even Jessica Jones eventually gains immunity after a time, so we can already guess the low effectiveness of the virus at a certain point. Thanos can still suffer mind control, of sorts, as evidenced by Mantis, but even she was struggling to keep Thanos in line, and lets not forget Mantis is immensely powerful in her capacities, being able to keep an entire celestial in line. Overall, I'm afraid that, taking into account the scale, Kilgrave's virus would probably not be the best offense against Thanos, under my opinion, regardless of biological accuracy.
this site's page tells that the Soul Stone can manipulate souls; not necessarily control them.
Regarding the Chitauri virus, while it is possible it was specifically engineered as a weapon, I find it unlikely. And while the transmission is strange, Simmons is able to create an antiserum just like she would any human virus, so it should be taken that it largely behaves like any other human virus.
Yes, Thanos would have a stronger immune system than Jessica, but it took a lot for Jessica to overcome. Reva was the first person Jessica had ever killed, and it was that trauma (the psychological aspect) that caused her to start producing antibodies. In the case of Thanos, the only thing a stronger immune system would really do is cause Thanos to potentially create antibodies on his own and faster. So Kilgrave's control wouldn't last long, but it would happen long enough to get Thanos to do what is needed to save the universe, like destroy the stones.
What do you think?
