She doesn't possess any great ability other than she can become an underwater breather. But she is one to be most coveted by those who oppose the transcenderis.
Ambrosia is a very high spirited girl, her life was pretty normal for she doesn't possess any extraordinary abilities until:
a)they discovered that by consuming her hair, a mere mortal can turn into any type of transcenderi with seconds that can last up to 24 hours
b) her ability to breath under water can only be triggered if she consumes her own hair, but unlike its span time effects on mortals, her ability to do so can last until she decides to leave the body of water.
nothing special, just the study on her thesis
Her life was pretty normal, she never suspected herself of being one of them, her parents even treat "their kinds" like trash. but her opinions have always differed from her family.
When she was in College, she even based her Final Thesis on the possible genetic make-up of Transcenderis, though she wasn't able to finish it like she wanted it, her thesis received notable awards and some scientists and gov't officials offered to buy it from her on plans to continue the studies, she refused.
And the day that she begin to find a cure and save her life starts.... now!
