Would you believe I got the Dark Sea Shadow and Dark Stealth Elf from Activision as compensation for a glitch I'd been having problems with? Cuz it happened, Just leveled both up fully today. I already had the Nitro Stealth Stinger, so I got Nightfall for the Dark Sea Shadow and leveled them both to max. I now have a complete Dark Variant collection, of ALL Skylanders that were dark.
