Entire figure: Depth Charge with SpyTroops Shipwreck face graft
Mask and harpoon gun: JvC Wet Suit
Scuba gear and fins: Depth Charge
Knife: VvV Heavy Duty

I'd call this an LBC if it weren't for the ridiculous amount of work that went into removing the face from the Shipwreck figure and creating an appropriate-sized recess for it in the Depth Charge head.

I know lots of folks hate the fact that Shipwreck joined the SEALs, but honestly it makes sense to me that he'd cross train with those guys and go on missions with them. After all, the Joes only have so many Navy guys.

Anyway, Shipwreck's officially part of my Joe dive team, pictured below.
