ULC: masked man

These ulcs have been discovered in Europe where the Black plague has taken place; only 3 have been discovered. They all wear gas masks and toxin repellent clothing of a dark colour, protecting them from all toxic gases and liquids. They never remove their clothing or masks.
They fortunately speak English and French. They were arrested for supposedly letting toxins free to the air of the planet before the black plague took place. It is confirmed that they caused the plague. It wasn't to kill but it was to evolve humanity to their fullest.
It ended up failing, killing many in the process. The police officers sent them to us to contain them and they were all contained in a large prison cell with a bed, toilet, bath tub and sink. We made sure to keep them alive.
New toxins would be found in their cell and they were all taken and researched on; many of them were dangerous and deadly. Recently we've decided to remove their masks with gloves. We found out that these humanoid beings had 3 eyes, one on their foreheads and two more where normal human eyes would be.
We decided to collect some of their blood to find out why they have 3 eyes and we found out that their blood each was filled with toxic liquids, the same ones we researched.
We made sure to do further research on their blood and we contained them once again. They were making these toxins with their own blood. These beings aren't human as a normal human being would have died.
They refuse to stop their toxic creations until they are able to create the one to evolve humanity.
