Super World was originally thought to be a safe place by the humans, who still could not realize the power of the androids and thought that the Town Militia would keep them safe. However, the androids killed all of the soldiers, broke into the park, cut in line for a roller coaster and killed a security guard.
After Future Gohan and Future Trunks arrived, a battle broke out in the park. During the fight, Trunks steps in to try and assist Gohan but is nearly killed. Gohan is however able to save him and attempts to hide in the park, but Future Android 17 and Future Android 18 fire powerful energy blasts in hopes of drawing the two out of hiding. The blasts completely destroy the park and blast off one of Gohan's arms.
