When photos of Sigma Strike Duke first surfaced most people were seeing visions of customized HALO Master Chiefs and Starship Troopers.  Me?  I saw the perfect base for Deep Six, one of my favorite Joes.

Base Figure: Sigma Strike Duke w/ modified head
Accessories: Sea Ops Duke air tank and hoses and DSV / SSDuke helmet, Switchfire and holster

Deep Six was one of my favorite Joes as a kid and when I saw Sigma Strike Duke I knew he'd be the perfect base for a Deep Six custom.  I based it off the version 2 figure as its more futuristic than the big bulky suit of the first version.  With some simple smoothing out of Duke's hair and a little paint I had my Deep Six.  I did have to glue the visor on the helmet though as its original fit just didn't cut it.  The hard part was finding a suitable accessory for him.  So I used the SODuke DSV as the base, added the bendy lights from Tunnel Rats sled, an extra SODuke air tank and mask and harpoon gun, and a scope from a 1/6 rifle and had what I like to call the Dolphin Rescue and Recon Drone.

Code Name: Deep Six
Real Name: Willoughby, Malcolm R.
Deep Sea Diver

Primary Military Specialty: Master Diver
Secondary Military Specialty: S.E.A.L.

Deep Six enlisted in the Navy and underwent S.E.A.L. training.  After serving 6 months with the teams he realized that group operations weren't his specialty and applied for dive school where he found his true calling.  Excelling in deep sea excercises where all he had to depend on and worry about was himself was perfect for the solitary soldier.  Its not that Deep Six didn't do well with groups, he just prefers to work alone and deep sea diving is about as alone as you can get.  He set several dive records and served as an instructor before joining Sigma 6.  During a routine dive training exercise, Deep Six and his trainee stumbled on a Cobra operation. They were ambushed by Cobra EELs and the trainee suffered severe injuries and equipment damage.  Deep Six improvised a way to share oxygen with the trainee and managed to get both of them back to their sub base.  The trainee survived and when Hawk heard of this act of bravery and self sacrifice he invited Deep Six to join Sigma Six.  He serves as the teams primary dive trainer and works at perfecting his Dolphin Rescue and Recon Drone, an unmanned DSRV that houses an extensive sensor and camera package and an emergency air tank and mask.  It also carries a single torpedo launcher and can be programmed with a specific mission or controlled from a voice activated remote implanted in Deep Six's dive helmet.  Deep Six is extremely solitary almost to the point of being anti-social.  He spends his down time working the New York Times crossword puzzle alone in his quarters.  While he may seem distant and detached Deep Six is the first to volunteer for rescue missions and the team holds him in the highest regard.
