Evolved elemental master

When an elemental master evolves, their powers become stronger and more violent. They only evolve when they unlock their true selves and who they are as a person. Cole is the first character to evolve. At the end of the first book, Cole dies but is brought back because he evolves, which obviously wasn't known until the end of the second book. Jay evolves during his fight with Nadakhan at Chen's Island in Blast from the Past 2. His powers become strong enough to kill the djinn forever. Jay and Cole both have special powers now, like creating forcefields to protect the ones they love. For example, in the third/fourth book Cole creates a forcefield around Ben to keep him safe from the explosion. It is has not been mentioned how Jay was also safe in the storyline just yet but Jay was also protected, not from a forcefield made by himself, but rather by his mother, Libber, who is also evolved.
