Skull Helmet
Once you've gotten all the armors in the armory, there is a variation of the Pilot Helmet with a skull clearly seen in the visor. In order to get this helmet, every other armor in the armor and this helmet is only worth 2 credits I believe due to the fact that all other armor must be bought first. I've only seen one person with this helmet and he/she was at the highest rank Inheritor.
