Barry (Amphibia)

Background
Barry appears in the episode segment "Cursed!" as the main antagonist. He is first seen carrying a bucket of blue moon berries, which grows every ten years, until Anne and Sprig bumped into him. This caused Barry to drop the bucket, spilling the contents of berries in the process.

Later, he was discovered by Anne, Sprig, and Maddie in his secret hideout and revealed to the trio that he was the one responsible for placing the curse on Anne and Sprig. He did this out of spite when Anne and Sprig ruined his harvest of blue moon berries. Barry then engaged Maddie in a magic duel (tossing bags of hexes at each other). In the end, Maddie defeated Barry and transformed him into a monster bird creature.

Personalty
At first, Barry seems like nice friendly guy who you'd stumble upon. However he is later revealed to have unforgiving nature with farade of niceess that he beatantly admits.
