Popuko

Popuko (ポプ子) is one of the two main characters in Pop Team Epic. She's a fourteen-year-old girl who goes on adventures with Pipimi, who is the series' mascot and usually wields a nail bat as a weapon. She is the shorter one of the duo and is prone to anger.

Chapter 8
One of the strips has Popuko eating a potato with a bud on it, disregarding Pipimi's warning that it's poisonous. The potato ends up turning Popuko into a muscular demon with wings.
