10 Doctor Who Revival Era Monsters And Villains That Deserve To Return
3. Krillitane
School reunion was one of the best episodes when for modern audiences growing up with Doctor Who. A returning classic companion, K9, and a visually interesting monster.
The Krillitane are a large bat like monster, who try to take control of the universe by cracking a complex math problem. A lot about what makes this episode special is great because it can’t be repeated. But the Krillitane are a usefully diverse creation.
They change their physiology depending on the planets they invade and races they kill, a very interesting dynamic. And this is too interesting to leave alone. We could have the Krillitane return and be in a completely different from, or something half way between what we knew them to look like and something else.
A crude comparison on how they might be brought back is the example of the Macra in series 3, who are related to, but vastly different from the monster that appeared in the classic series. Either way, there is a lot of room for manoeuvre with this entry.
