Key Episodes:

Analysis: This is the horror-themed arc. Episodes lean into darker visuals and body horror (Malware’s assimilation). The standout is “The Color of Monkey” (S3E10) where Ben transforms into a new alien, Whampire, for the first time. The arc ends with Ben temporarily losing control of the Omnitrix due to a DNA splice. ben 10: omniverse episodes
