Whomper

The Whomper is a fictional Nerf blaster that appeared in Nerf Arena Blast.

Details
The Whomper is the strongest and slowest-firing blaster in Nerf Arena Blast. It is also the only blaster in the game to be an energy-based weapon, running on Whomper Batteries rather than traditional physical ammunition. The Whomper will have a default charge of one blast, even if the player does not have a Whomper Battery in their inventory.

Primary fire
When the player fires the blaster, it goes into a two second "charging up" animation before releasing a large, slow moving sphere of energy. This detonates on contact with anything, causing a large explosion that knocks out everyone in range, including the one who fired the blaster.

Alternate fire
The Whomper's alternate fire makes the blast larger and stronger, but at a very risky trade-off; if the player is hit while in the two second "charge up" animation, they will "explode". This represents the weapon getting damaged during the charging process, causing a chain reaction that detonates the weapon, taking its wielder with it.
