Goku, the Saiyan warrior

New champ idea, we need something from dragon ball Z

I was thinking along the idea of sticking with Goku

Skills:

Passive: while stationary Goku charges his power bar (similar to the power bar of tryndamere or renekton). - set rate ? Timing delay before charge starts? Possible stages of charge? Super saiyan 2? Slower movement when no energy is charged?

Q- K.O cannon - dashes to target dealing area damage along with a % of attack damage (consumes energy and, upon impact slight hp cost)

W- kamehameha - 2 second charge time to release an energy blast controllable by mouse movement. Goku cannot move during the attack. Deals damage in a direct line behind first target hit. Consumes Energy (possibly only cast as super saiyan 2?) scaled with attack damage?

E- dash - dashes to mouse decided area becoming untargetable for 0.5s. Energy consumed (no damage on this skill)

R- Spirit bomb - can only be cast during max energy. Consumes all energy to generate a large blast (similar to zigs ult) hitting with area affect and igniting all enemies affected. Once discharged Goku looses all movement for 2 seconds. If an enemy champ is killed by spirit bomb, Goku gains half his energy in return. (Scaled with number of nearby friendly champs present? More champs more damage? )
