Byeonsinjadongcha Tobot 15th Season

Ondal is often left alone whenever his older brother Ogong rushes away to protect Daedo City. His loneliness gradually draws him into a smartphone game, and the calculating Angela notices exactly how deeply he has become attached to it.

Angela wins Ondal's trust, kidnaps him, and uses him as bait to seize Tobot W. After turning W against its own allies, she forces the Tobots into a painful fight where defeating the enemy also means rescuing a friend and restoring a machine that was never meant to hurt them.
