For Experiment#666 (giant one) I used BAF Ultimate Goblin arm and head. Swapped feet with Superior Spiderman. Hand from Tomas Jane Punisher. Vest from Sigma 6 Duke. For X I used MU Series 2 Grey Hulk for arms, FF Spider- man for head(a little paint added to head), a buckle thing from Age of Thunder Thor, and for the legs I used MU Drax. X is the one who took RockFeller(if you haven't seen him, check him out!) to his planet and experimented on him. X has many dangerous experiments but Experiment#666 is the most dangerous of them all. These characters are also pulled from my imagination so I hope you like them! As always let me know what you think!
