Zap-cap

The Zap-Cap is an invention made by Static's bestfriend and eventually sidekick, Richie Foley, known to the hero world as Gear.

Mark I
The original Zap-Cap edition, later known as the Zap-Cap Mark I, was used by Static. They were grenades of electromagnetic energy, to be used if his powers were shorted out. At the time, Static's powers were sporatic at best, and changed upon the day, sunspots, or just simply running out of energy. When Static gained a full knowledge and controlling off his electrical powers, these Mark I Zap-Caps became outdated and ineffective, virtually useless, so Gear came up with another model that could help them in battle. He configured them to just explode. Yet, he had an idea for another configuration to make their job easier.

Mark II
Thus, Gear made the Zap-Cap Mark II, a modification to the original Zap-Cap to make them grenade-like balls with metal bands for restraining purposes. This would be used in combat to obviously restrain, and then at the end of battle could be used to keep people there until the police showed up. These proved time and time again to be a valuable weapon in the arsenal of both Static and Gear and later with their prodigy, Black Streak who uses the Zap-Cap Mark II quite frequently.
