Doctor Who Doctors by companion era

What this quiz covers

Companions often define a Doctor’s tone, stories, and season identity—this quiz asks you to connect Doctors to the companion era they’re best associated with. Expect a mix of classic and modern references, including overlaps, handovers, and short-lived TARDIS teams.

You’ll answer in a multiple-choice format with 4 options and no timer, so you can focus on reasoning through each era rather than rushing.

Skills you’ll practice

• Recognizing which companions belong to which Doctor’s main run
• Placing companions in the right era when casts overlap across seasons
• Separating TV companion groups from one-off allies and recurring characters
• Remembering regeneration transition periods and “bridge” companions
• Spotting era-defining pairings versus brief travel stints

Common pitfalls and how difficulty works

A frequent trap is mixing companions who appear close together in broadcast order but belong to different Doctors, especially around regenerations and mid-season shifts. Another is assuming a companion’s first appearance equals their main “era,” even when their defining run is later.

Difficulty is balanced as Mixed: you’ll see straightforward iconic pairings alongside deeper cuts and edge cases. Before starting, choose your question count and difficulty to tailor the length and challenge—shorter sets are great for quick refreshers, while longer runs better reveal gaps across the full companion timeline.
