Biokinesis is not the change of DNA, it is the alteration of cell's, often i say to people, that if they want to be a mermaid, this is literally there only option. ALthough i do not believe in it, as it i have seen no proof. I don't believe in the kinesis, but i advertise to spread the options.
I myself do believe in that anything is possible. But that it may just take a greater amount of needed requirements in order to achieve it. Theres not much said for Biokinesis, indeed probably the most difficult kinesis to understand.
