They should not. And this post lacks info or reasons.
If you know why they are immune to bleed then there is no need to explain why they should be immune to poison.
They shouldn't, really. Blood is not "a must" thing to have for someone to be poisoned. Besides, they have blood. They just have an armor on their body or so. Totally should still get poisoned
they are not immune to bleed due to armor, they are immune bcz their ability is to transform their body into organic steel fully lol I am not saying that hulkbuster, warmachine or iron-patriot should be immunr to poison bcz they have armors and their whole body is not metallic so armor is not the point here.
Still ... why should they be immune to poison? You're saying they can't be poisoned just because they have an organic steel body? You can still totally poison them
lol then you can poison ultron vision and nebula too.
No ... they are robots. They are affected by a cybernetic virus, not poison. Colossus is not a robot ...
you are changing your point of view every then and now, first you said they have armors now you are saying that a steel body that can't bleed can be poisoned lol but can't bleed lol
Guess you just are misunderstanding waht everyone is saying ...
Colossus and UC are living beings, with blood. The game used an excuse that they have a steel body to give them bleed immunity. Due to being living creatures without resistance to poison, they can totally be poisoned (because again, a steel body won't do anything to protect them against poison). Robots are not living beings. They don't have blood, and then they can't bleed. In addition, due to being robots, they are also immune to poison.
if they are living beings with blood then they must not be immune to bleed.
They are protected from bleeding by the organic steel plating. However, as @will-o-wisp said, they do possess blood and therefore can be poisoned.
poison first eneters into bloodstream and if they are immune to bleed due to that tough metal then you can't poisoned them lol
Colossus can turn his flesh and bone into organic steel via psionic interface with an alternate dimension that basically swaps his carbon based atoms with his body for osmium based ones, as described in detail above by @DNA3000. He remains an organic being, despite his amoured organic steel form. As poison can only affect organic beings via chemical reactions or another similar activity on a molecular scale, it stands to reason that Colossus can be poisoned.
ok then ultron, vision and nebula can be poisoned too.
No they cannot. They are not organic, but possess robotic parts. The difference between they and Colossus is that Colussus still possesses organic properties. There is nothing organic about Ultron, Vision or Nebula.
we are talking about poison and not neurotoxin. if a steel body can be poisoned then others steel bodies can be poisoned too robots also.
Neurotoxin is a poison that exclusively affects nerve tissue, which funnily enough is organic. Colossus is organic steel and can be poisoned. The metal of Ultron, Vision etc is not organic and therefore cannot be poisoned.
He needs fire resistance, cold, and shock resistance and ability to shrug off magic. Like he's a tank and the strongest strength-wise mutant. Unstoppable Colossus is just...not like his game counterpart at all, and everyone is better off. he would easily be the best everything in the game dang near. He's immune to everything, has a 1ft Force Field and can reach speeds of 111mph. Yea, you honestly want to face that AW boss?

By that reasoning, he could theoretically have his armour broken. However, as below, it is not easy to do.
Quote from marvel.wikia: His armored form can withstand ballistic penetration, including that of a 110 millimeter Howitzer shell. He can survive temperature extremes from 70 degrees Fahrenheit above absolute zero (-390 degrees Fahrenheit) to approximately 9000 degrees Fahrenheit. He can survive a collision with a loaded, one ton flatbed truck at 100 miles per hour or an explosion of 450 pounds of TNT. He can also survive falls from great heights while in his armored body. Colossus' armored form cannot rust under normal Earth conditions.Furthermore, his eyes become steel-like and allowing his eyeballs to withstand and deflect even the impact of a .45 caliber bullet.

your logic is funnier than kabam's logic
Now I see where you are wrong. You can't use real world logic on a fictional universe. Even if you did, you would still be wrong. Plants don't have blood, yet they are totally poisoned on both real world and in this game. Some humans in the real world developed poison immunity (to some specific poisons), and the same happens in this game (the difference is, there is just one type of poison here, so no one is exclusively immune to one poison and not to another).

here I can agree with you but a lots of champs need so much improvement.
They should not. And this post lacks info or reasons.
I agree. Although Colossus does not need to breathe in his metal form, he is not invulnerable to poison. UC is a different matter, as in the comics Juggernaut cannot be killed by poison.
They should not. And this post lacks info or reasons.
If you know why they are immune to bleed then there is no need to explain why they should be immune to poison.
They are immune to bleed in the game because that immunity roughly corresponds to the fact that they don't have blood or other circulatory system that would cause a slicing attack to cause additional harm over time via the loss of blood. It is important to note that Colossus is immune to bleed *effects*, but not the effects of attacks that *cause* bleed. Slicing him deals damage, because the slice itself *is* damage. But there's just no further loss of health from being cut.
Poisons work by interfering with the chemical or other molecular reactions that sustain the life of the organism. Poisons do not need to enter a bloodstream to work: animals like jellyfish with no circulation system at all can be poisoned, and poisons can work without entering the blood stream of animals that have blood. They can be absorbed and diffuse through an animal to work. If Colossus was just a block of metal, he'd be an inert paperweight. Stuff must be happening inside him, even if that stuff is happening to an all metallic body. That stuff can be interfered with.
This may no longer be canonical, but I remember that in the Handbook of the Marvel Universe it was stated that Colossus transformed into his metallic form by essentially recreating his body using osmium atoms replacing his carbon atoms while maintaining roughly the same functionality but with significantly enhanced durability. If that's still remotely canonical, then while Colossus would not be vulnerable to most normal poisons that affect normal people, simply because his body chemistry is so different from normal people, he would still theoretically be vulnerable to poisons, just ones that work on his special chemistry.
This is only half correct @DNA3000. Immunity to bleed in this game happens for two reasons: A. a lack of bleed, such at is the case for Dormammu, Morningstar and Ghost Rider or B. near impregnable skin, which is the case for Luke Cage, Emma Frost's diamond form and Colossus. In the comics, not even Wolverine's adamantium claws could go through Colossus' metal skin.
I agree how difficult the comic book writers make things in order to understand the mechanics of their characters realistically. While we know Colossus does not need food, water or air to survive, nothing is mentioned about poison. In MCoC poison can range from radioactivity (Abomination), ant venom (Ant-Man), 'spirit venom' (Doctor Voodoo) to plant-based venoms (King Groot). Each can react physically and chemically different to Colossus. So maybe he is poison immune, maybe not.
You can burn steel. It isn't clear what Colossus is actually made of, since they keep changing this in the comics, but even if that material can't combust it can still be damaged by the right application of heat or other energy ("incinerate" damage in the game isn't just ordinary heat; it includes other related types of damage like Hyperion's laser beam eye attacks).
Steel doesn't burn that easily (otherwise you wouldn't use it as cooking gear). For something to combust into flames and turn to ash, it needs to cause a chain reaction that causes the material to completely chemically reduce itself. Metals however have the capability of forming a passivating metal oxide layer which protects the underlying metal: https://en.wikipedia.org/wiki/Passivation_(chemistry)
As stated in your article about chlorine trifluoride:
"It can be kept in some of the ordinary structural metals — steel, copper, aluminium, etc. — because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminium keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire."
So yeah, you can throw chlorine trifluoride to Colossus and he will not care anyway. The passivating metal oxide will protect him from further reduction.
What about heat, though? Osmium has the fifth highest melting temperature of all elements, melting at a staggering 3033 °C or 5491 °F. Colossus can swim in lava (+/- 1200 °C) if he wants to. In the comics, he is resistant to burn and electric shock.
The only mistake that is made in the comics is cold: although Colossus can perfectly go to the Antarctic for a walk, it would make his skin brittle. This is dramatised if he goes from room temperature to absolute zero, like Iceman can. For every metal, the ductile-brittleness transition temperature (https://en.wikipedia.org/wiki/Ductility#Ductile-brittle_transition_temperature) is different.

Poisons work by disrupting chemical or molecular reactions. Colossus's body needs those to function, and thus can be poisoned. Ultron does not, and thus cannot. The fact that they have metallic bodies is not important here.

So yeah, you can throw chlorine trifluoride to Colossus and he will not care anyway. The passivating metal oxide will protect him from further reduction.
Yeah, no. I think you're overgeneralizing superficial Google searches a little too much. Yes, many metals do form passivating oxide layers, and yes this will happen for certain metals and fluorine, so it is possible to passivate something like a steel container with either fluorine gas or chlorine trifluoride itself to form a metallic fluorine layer. However, if you dump ClF3 on a steel or similar metallic object the size of Colossus, it would probably just explode. The reaction would be too energetic for the metallic fluorine layer to form, or it might form and then immediately vaporize. And the slightest bit of dust on Colossus that had absorbed any moisture from the air would react energetically with ClF3 to form hydrochloric and hydrofluoric acids, which would prevent the metallic fluorine layer from forming.
The closest thing I could find generally available to read on the internet that hints at the passivation requirements is a safety data sheet for ClF3: https://www.scribd.com/doc/70607697/Safetygram-39-ClF3. See the section "System Preparation" that cautions on slowly performing passivation with increasing concentrations of ClF3 to ensure the passivation reactions don't generate too much heat too quickly.
Also, steel wool combusts. The issue isn't the oxide layer that forms during oxidation, it is the ratio of surface area to volume, which limits the heat per unit volume generated. Below a certain ratio the reaction is not self-sustaining. Above a critical ratio, it is and the material can spontaneously combust once ignition occurs.

If there would be a supervillain who uses ClF3, Beast would take the necessary precautions. Colossus would be cleaned, put in a vacuum container and then slowly treated by ClF3 gas to ensure passivating, so he wouldn't explode in a fight. Colossus would still beat the supervillain. But then again, most fire-based supervillains are entirely different.

Neurotoxin is a poison that exclusively affects nerve tissue, which funnily enough is organic. Colossus is organic steel and can be poisoned. The metal of Ultron, Vision etc is not organic and therefore cannot be poisoned.
lol organic steel can't be poisoned if it doesn't have blood.
The steel itself is armour plating that protects him from bleeding. He still possesses osmium-based blood.
then armor can be break easily by any champ which possess both qualities armor break and bleed and then they should not be immune to bleed.
