Coolest Godzilla Monster Besides Godzilla

We've got a topic asking which Godzilla monster had the worst design and purpose, so I thought I'd ask a similar question, but asking what everyone thinks is the coolest Godzilla monster besides Godzilla himself. For me, my all time favorite monster besides Godzilla has always been [b]Gigan[/b]. He is one of the Monsters I feel was short-changed many times when facing Godzilla. I think given a realistic scenario, [b]Gigan[/b] could very well come close to putting an end to Godzilla's reign. A Giant cyborg with scythe blades for hands, a buzz-saw on his chest, an Alien energy projectile and the ability to teleport and fly! Suffice to say, [b]Gigan[/b] is one bad mother.
