Start the Dr. Aeon Strike Force on Malicious (1 star) Advanced Mode setting or higher. This allows King Midas to summon Ripple Singularities, with the appearance of blue beams, in the seventh and final mission. Do not allow any team members to take any damage from these blue beams.

The blue beams will always target the player furthest from King Midas, but never the same player twice in a row. Two people alternating allowing themselves to be targeted usually works. However, sometimes the beam starts to fire as the team is being teleported into a ripple (when Midas is at 75/50/25% health), so everyone will have to move as soon as they are able when this occurs. A good way to avoid this is for the team to make sure they're not about to hit one of those HP thresholds when a beam is due to spawn.
