Dark Weefager is a corrupted clone of Weefager that hunts the real Weefager down and stalks him wherever he goes. When the time is right, his presence darkens the sky as he chases Weefager down for a total of 112 seconds. When Weefager becomes too fast and nimble for him to keep chasing him, he proceeds back into the shadows and waits for his next chance to strike. He is the main antagonist of WDOW.
