He first appeared in the episode April's Artifact, where April tells the turtles that her uncle loves to travel, but then mysteriously disappeared. April had no clue where her uncle had gone. But then April and the Turtles get teleported to a weird dimension where Giant Wasps live via a strange artifact that had belonged to Augustus. April and the Turtles discover that August was teleported to the same dimension after finding his journal, having accidentally activating an artifact he was looking at. April and the Turtles got out of the dimension, but no sign of Augustus. Apparently, the wasp queen interrupted him when he was attempting to dial Earth and instead went to another dimension.
