Head, harness: DTC Interrogator
Everything else: 25th Crimson Guard

In the early days of the 25th Anniversary line, this was a common recipe for an Interrogator custom. It was done several times by different customizers. For my custom, I did not stray too far from the established recipe and for a few years, this was the main representation of this character in my collection.

When the Small Playsets Group Project came around, I updated the recipe for my Viper Lockdown. Pictures are available in the Group Projects menu.
