The Human Blender (Doom's Level 3 Hyper Combo Doom's Time in MvC series) is what Doctor Doom uses to finish off an enemy, although less frequent than his other trademark move, the "Finger Lasers".
Assist Me! Featuring Wesker Part 3Edit
The attack's first appearance, after weakening Wesker with the Finger Lasers, he used this for the first time on camera and outside the game to finish off Albert Wesker in his fight against him.
Assist Me! Featuring Taskmaster Part 2Edit
Doctor Doom used this to finish off Taskmaster after M.O.D.O.K. and Deadpool were incapacitated.
