Gilthunder is highly skilled at utilizing Thunderbolt, using the power to greatly increase his physical capabilities and allow him to move at extraordinary speeds.
The power is remarkably versatile and can be used in a number of ways, allowing him to perform such feats as creating rings of lightning that bind and paralyze his opponents or imbuing his sword with lightning and stabbing it into the ground to seal off an underground water source. By imbuing a weapon with lightning, its destructive potential vastly increases. In addition to being able to channel lightning through weaponry, he can discharge large amounts of it from his body.
