This is a Bandai 5055737 HG 1/144 R08 Calamity Gundam Seed

Celebrating the 10 anniversary of Gundam Seed (and the rerelease of the anime on Blu-ray) Bandai has released their 'remastered' versions of their great HG kits from years gone by. Calamity Gundam is identical to the initial release but now comes in colors matching the Blu-ray anime, marking stickers, and an extra part that lets you attach Calamity Gundam to an action base 2 (sold separately).

This is a posable, high-grade or better injection-plastic kit of an item from the Gundam universe.
