Ben is approached by video game producer Oliver Thompson, who invites Ben to be the star of his own video game, scanning Ben’s alien forms into a computer for motion capture. In reality, however, Oliver is in the employ of Will Harangue, who is developing a battle robot called the Stalker to target and destroy Ben by analyzing and predicting his moves. The Stalker attacks and nearly kills Ben, but Harangue holds back, wishing to exploit Ben’s battles with the Stalker for television ratings. He publicly challenges Ben to a final battle at the National Mall in Washington, D.C. Ben is able to defeat the Stalker by using Nanomech, who was too small for the computer to scan; subsequently, Ben uses Way Big to crush the Stalker as well as Harangue’s car.
