Friar Serra, the mummy from Scooby-Doo! Mystery Incorporated's "Theater of Doom" was actually a real-life friar, who was also Spanish and part of the Franciscan Order (as Friar Serra also was in the episode). Friar Serra founded a mission to Baja California and went on 21 Spanish missions during his time as a friar. Despite the fact that he died in 1788, he ironically was just recently declared a saint by Pope Francis in 2015.
