Amarantha sweet and faire,
Ah brade no more that shining haire!
As my curious hand or eye,
Hovering round thee, let it flye.
Amarantha was born in 1954, to Roger and Rose Bellamy. Roger was a biologist, and Rose was a botanist. She spent most of her childhood always travelling around with her parents, who were always in some jungle or remote part of the world studying plants and such. When she hit puberty at the age of 12, her powers started to come in, at first her parents were a bit shocked, but as they were botanists, the idea that she could control plants, kept them from allowing her to go to Xavier's institute.
At the age of 16, her parents were working on a top secret project for the government, although Amarantha never understood the details, there were numerous groups who desired to steal the projects. As her and her parents were on an expedition deep in the rain forest, a group of mercenaries came upon them, some bullets were exchanged, but soon one of the mercenaries had Amarantha's mother at gun point, demanding they give over the results of their research. As the tension increased, Amarantha suffered a psychotic break, loosing total control of her powers. Plant life around them, vines, etc started growing out of control. Amidst the plants happened to be a fairly large quantity of belladonna and Abrus precatorius, or Rosary Pea, both highly toxic, between the vines and the poison, it wasn't long before everyone around her was dead, the use of her powers caused her to loose consciousness. Shortly after, Professor X, sensing what was happening, sent a team to recover her. While at the Institute recovering, Professor X put a wall up in her psyche, blocking out the painful memories, so that she could learn to control and develop her powers. Professor X also found, that due to the sudden burst of her powers along with being subjected to the various poisons, slowed her ageing process. He deduced that she ages roughly 1 year to every 10 to 11 actual years.
For years she was quite happy with the x-men, even falling in love with another member, Nathan. That was until 3 years ago, when Professor X was killed, her grief was enormous, not even Nathan could console her and caused the wall keeping her memories back to come crumbling down. She ran off, seeking vengeance on anyone who had ever hurt her or her loved ones. Poison ran through her veins and her physical appearance changed. She killed any and all who got in her way, with no regard for collateral damage. After months, a team of X-Men was sent to track her down, Nathan did everything he could to make sure he was on the team, still convinced she could be reasoned with. When they finally tracked her down and cornered her, she lashed out, and a fight ensued. The team outnumbered and outpowered her, seeing her helpless and injured was more than Nathan could take, and he intervened, giving her the time she needed to get away.
For the last two years, she has laid low, learning how to control her emotions and her powers on her own, she has returned, but still has vengeance in her heart, so instead of seeking solace back with the X-Men, she has chosen to seek out and join the Revengers.
