The Series-2 BurroWeavil is the infiltrator of the nano-bug forces. Swarms of these robots are released onto an enemy ship, unbeknownst to the pilots, and can hack almost any computer in under a second. Using special electricity-sensing-radar, the BurroWeavil drills into the ship and attempts to find wires located in the walls. After finding said wires, the small spin at the tip of a BurroWeavil's drill is inserted into the wire and forms a direct link to the ship's computer. The robot then broadcasts every scrap of information it finds back to the ship which released it, sending vast amounts of valuable information without a single person knowing.
I may or may not make more of these, depending on whether I can find more Bionicle masks :P
