Maybe the hero she's looking for is herself?
Think about it, Poppy has been to numerous villages looking for a great hero, but she hasn't found him/her at all. In the comic she was the one to defeat the giant monster, so maybe she is the hero??

Her lore states that she is.
"The hallmarks of a great hero are almost always obvious, especially to the person displaying them. Almost always. Poppy’s been tasked with delivering a legendary hammer to a hero who will become legend. Journeying through Runeterra, she uncovers a number of would-be wielders, but never suspects the hammer might have found the right person already."
