First I swapped the arms with the most recent Lizard figure. Then I carved the feet off the Lizards legs and modified them to fit on the foot posts of the Darkness figure.
Then I used some Aves to smooth out the legs and center torso, and added the trim on the knee pads. I molded the green part of the costume on using Aves, and gave it texture by rolling a sculpt tool over it. The belt is made from a flipped over ammo strip. The shoulder pads are made from the shin guards of the HoM Wolverine. The gold trim was made from Strip Styrene.
The head is made by cutting out the eyes from a Venom head. Inserting eyes from a Moon Knight head and using Aves to add the black wrappings.
