A superb multi-verse hopping adventurer created by Bryan Talbot.

A vintage fan pic interpretation of the character:

There are three main books in the Luther Arkwright saga.
Read them in this order:

1. The Adventures of Luther Arkwright (1978–1989)

The original and most famous storyline.
Often collected in a single volume.

2. Heart of Empire: The Legacy of Luther Arkwright (1999–2001)

A sequel set many years later.
Focus shifts partly to new characters while continuing Arkwright’s legacy.

3. The Legend of Luther Arkwright (2022)

A modern continuation.
Brings Arkwright back into the spotlight for a new multiverse threat.
