If there’s something Doctor Who is renowned for, aside from time travel adventures, sonic screwdrivers, and the phenomenon of regeneration, it's the extensive array of memorable monsters that populate its universe. As we embark on a new season of Doctor Who, it’s the perfect time to revisit the Doctor’s rogues gallery and spotlight the most formidable creatures the Time Lord has encountered.

Before delving into our list, a few clarifications: We've excluded characters that don't fit the traditional definition of "monsters," so iconic villains like the Master won't appear here. Furthermore, while some of these creatures have roots in the classic series, each one has been featured in at least one episode since the 2005 revival. We believe the "modern" monsters have a greater impact and align more closely with contemporary audiences. With these points in mind, let's explore the list. Here are the top 20 Doctor Who monsters of the modern era.
