Grenadier allows its user to charge a ball of condensed energy in their hand.
As stated above, users of Grenadier can condense energy into spheres at least one of their hands. These spheres glow in the user's signature colour.
Strengths and Weaknesses Edit
What these energy balls do is unknown except that they are probably destructive and might be explosive.
The larger the size of the energy sphere, the more time it takes to charge one. Other limitations are unknown.
