This is an interesting personality, playing the role of the enigmatic and elusive puppet master.
Alchemy is an interesting name for an individual in this position. Alchemy, once upon a time, was a set of spiritual beliefs combined with primitive chemistry that held several very outstanding goals. Of those goals was to develop what is called the panacea; an elixir of capable of ridding the imbiber of all diseases, and granting everlasting life.
This is not unlike the goals held by Evoke's Alchemy. He seeks to be the catalyst of a global panacea. A grand remedy to the troubles that plague our world. Enshrouded by a veil of mystery and a pair of really cool sun gla****, he guides his agents to their missions in confidence. But where does this confidence come from?
Another goal of the Alchemy of old was the transformation of various mundane metals into gold(or silver). This was fueled by greed, but there is a certain sense of selflessness to Evoke's Alchemy. Instead of metal, he works with mundane people, turning them into extraordinary innovators using the skills they already possess, and by partnering them with an entire network of other agents possessing a plethora of other abilities.
Alchemy, such a fitting name for an empower-er of people.
