The PPG are a clear shout-out to The Powerpuff Girls, the first show created by Craig McCracken. They're a trio composed of an orange haired leader voiced by Cathy Cavadini, with her two partners being a blond haired agent voiced by Tara Strong and a black haired agent voiced by EG Daily. In addition, the names of the characters also match the respective power scheme of the girls (Agent Pink/Blossom, Agent Blue/Bubbles, and Agent Green/Buttercup).
