About this creation
At DEFensive CONdition 5, it's a party, with drinks and decadent desserts!
At DEFCON 4, Robbie shares the abundance of essential foodstuffs, like fruits and grains.
At DEFCON 3, with the threat of violence, Robbie is supplied with a riot shield and stun gun.
At DEFCON 2, when the situation gets worse, so does the damage that Robbie can dish out, with a flame-thrower and sniper rifle.
At DEFCON 1, in the worstest of worst case scenarios, e.g. a zombie Armageddon, Robbie goes full tactical!
Ready for operation on land, in sea & air, Robbie is equipped with a jet glider, dive flippers and armed with missiles, a sonic blaster, a high-power green laser, a chain saw AND a buzz saw. Rip 'em up, Robbie!
