Name: Brand Hue
Villain name: Apacol
Photos:

Age: 41
Seeming to have the traits:
Abilities: Telepathic abilities, Toxins he can release from his mouth, ears, nose that can be posionus to breathe. The toxins are visible as a gas that he controls where it travels, it doesn't have to be posionus however, and can be simply used to create other gases such as helium, methane (to create a spark/fire), and others such as that.
Known weaknesses: Has been defeated only twice before by being attacked by multiple heroes by encasing him in a room/place without his mask. Getting him to breathe in his own toxins. (When he breaths in his toxins he passes out, but never dies). Wearing a gas mask, and ear plugs can also be used to not breathe in his toxic air.
Job: Unknown
Alliance: Never known to play fair
Backstory: A former student gone rouge after a classroom incident that left half of the class critically injured. He was then expelled, and thus outcasted. In encounters with the villain heroes have remarked him saying a few things;
'The end of the world in nearing'
'I think it's time for your extinction'
'Are you getting sleepy? Maybe it's best you sleep...permanently'
'I was chosen for a reason'
This has led many to believe with the addition of his name that the male wishes to being upon the end of the human race, and create a new one in his own image. No
Whereabouts now: It's unknown if where his lair resides
Other information: His symbols are a gas mask, drama mask, and cursive letters in green or red blood on the wall. Also a expert chemist, having gone to a normal school and getting a degree. Interesting fact is that depending on the chemical, his eyes will change color

Quickly the two fell in love, and with it they hit it off quite nicely. Her bright nature mixed with his dark one created a well balanced team. Together they signed up for the space program, and with that the went off to fight more universal villans. However a few years down the line things got heated with her now husband, and after the fight they broke up resulting in one of the longest earth eclipse in history. Leona didn't get away from the relationship free however, she had became pregnant around the same time they broke up and for the 8 months she carried the horror that was her and Sean's baby. She couldn't hate the baby no more when it was born though after seeing the little baby girl.
