The Har-Doom

The Har-Doom is some kind of harpoon-like gun used by Darwin Archimedes upon being startled in his lair by Andrew Wheatley. Darwin later reveals that it is actually used for watering plants and thus is not very dangerous at all.

It is presumably Reloovian technology as produced by the planet Reloo.

Appearance
The Har-Doom is large, red-themed and very pointy. At one end is a dangerous-looking syringe and at the other is a compartment full of glowing energy.

Abilities
When fired, the Har-Doom projects a small stream of water which is completely useless against giant robots.
