COSTUME: Handmade
Mysterio's head is actually a 'petrol' coloured marble; doesn't show up too well here but there are some gorgeous golds, greens, purples and blues in there. It is too spherical though... hopefully I'll find a better dome amid the Xmas tree baubles this year.
Drew the grid onto the material before cutting and assembling the outfit. His cloak's clasps were made from milliput. the gauntlets? Craft foam - 4 pieces to make an open top/bottom box around the arm. Bits of wire were pushed into the twirly ends of the gauntlets, to try to keep them at an angle... an experiment about 70% successful.
He also sports Iron Man's boots (with more craft foam as the 'boot cuffs') and the Green Goblin's hands,
