Behemoth

Can you imagine yourself on a futuristic battlefield, adrenaline pumping after a small exchange with an enemy mech and exhausted from a long war, just to see this thing bearing down on you? Obviously with insanely superior firepower and size advantage, camouflage is completely optional. In fact this one by Moko says "Hey guys! Check me out! I'm coming to destroy you now!"

Steampunk Gundam

Mashups are all the rage, you can't go anywhere without seeing a Star Wars this or a Doctor Who that. But just taking two or more beloved franchises or themes and mashing them together isn't enough, there's got to be a clever hook, some humor or in the case of this Steampunk Gundam by M<0><0>DSWIM, totally badassery. I want to see this thing storming the battlefield, I want to hear the chuff and joints squeal, I want to smell the coal burning. This thing is awesome.
