If there's one thing Doctor Who is renowned for, apart from its time-travel adventures, sonic screwdrivers, and the phenomenon of regeneration, it's the extensive array of memorable monsters that have populated its universe. With the new season of Doctor Who now airing, we're taking the opportunity to delve into the Doctor's rogues gallery, spotlighting the most ferocious monsters that have challenged our beloved Time Lord throughout the series.

Before we dive in, a few clarifications: We've excluded characters we don't classify as "monsters" in the traditional sense, so iconic villains like the Master won't feature here. Moreover, while some of these creatures hail from the classic series, each entry on our list has appeared at least once since the show's revival in 2005. We believe that the "modern" monsters often have a more significant impact and are more relevant to current audiences. With these points in mind, let's explore. Here are our top 20 Doctor Who monsters of the modern era.
