Medusa's killer Penny meets Irish American (7)

I believe the answer is:

perseus

(Other definitions for perseus that I've seen before include "Medusan killer" , "legendary hero" , "'Having slain Medusa, he became a constellation (7)'" , "Group of stars" , "Medusa's slayer" .)

I've seen this clue in The Sun.
