Basically a lot of marvel universe figures.
My X-Men team is formed by Angel, Storm, Iceman, Beast, Shadow-cat, Colossus, Warpath, Polaris, Havoc, Psylocke, Rogue, Gambit, Nightcrawler, Wolverine, Banshee, Cyclops and Jean Grey.

Jean Grey was made from a Lady Sif and a Rogue with lot of sculpting for the hair.
Dagger to make Rogue, Mara Jade and the legs of snake eyes to make Psylocke
Cyclops was made from an Spider man bag head
Storm is made from a Black widow.
For Iceman I used a GI Joe’s Duke.
Another Duke to make Havok.
Han Solo was the base to make Banshee.
A Padme´s head in a Black widow’s body made the trick to have a Kitty Pride.
And a Loki’s head to custom my Gambit.
All with black gloss, brown and gold paint.
