<weewoo! weewoo! weewoo!> Giant Dragon Alert! We have Giant Dragon Alert! But, this one's probably not going to just destroy us for no reason. That's because it's the generally-gregarious Adult Silver dragon from WizKids as part of their D&D Icons of the Realms line. Pre-orders are being taken now.
From the website:
The friendliest and most social of the metallic dragons, silver dragons cheerfully assist good creatures in need.
A silver dragon shimmers as if sculpted from pure metal, its face given a noble cast by its high eyes and sweeping beard-like chin spikes. A spiny frill rises high over its head, tracing down its neck to the tip of its tail. As the dragon approaches adulthood, its color gradually brightens until its individual scales are barely visible. As a silver dragon grows older, its pupils fade until its eyes resemble orbs of mercury.
