Costume Unlock Item
There are a number of items in Champions Online that can unlock costume pieces. Most items are specifically for unlocking costume pieces, while others are actual upgrades or Power Replace Items that can unlock costume pieces. In order to unlock a costume piece from an unlock item, the item must be double clicked (it will then disappear from your inventory). To unlock a costume piece from an upgrade, the upgrade post be equipped (the upgrade will not disappear).
Additionally, all costume unlock items have a mask indicator on them. A gray mask indicates that a costume piece has already been unlocked while a blue mask indicates that the costume piece has not been unlocked.
These costume pieces unlock for every character on an account.
Listed below are sources and types of costume unlock items. Not listed here are the Power Replace Items, since that has its own dedicated section.
