Here are some great concept models and Mecha robots made from LEGOs. Complete with detailed descriptions too- Armament: Beam rifle x2 (~2 megawatt charge, stored in shoulder charging racks/weapons binders), clay bazooka (fed from 5-round clips, hand-carried). Even lighter armored than the L-Siren, V-Sirens are built for speed and agility above all else. Typically not armed with melee weapons, a V-Siren is most frequently seen slinging either its integral beam guns or a “clay bazooka”, a shotgun-like multi-payload launcher. [via] Link.
