Gundam - Perfect Grade - Unicorn Gundam 02 Banshee Norn

The PG Banshee Norn shares the same frame with the PG Unicorn Gundam but instead of the Unicorn's Gatlings and Bazooka you get that massive Norn backpack as well as the giant shield and parts to make the launcher for the rifle.  The Banshee comes with that giant display base and Detron stickers for markings.
