In ‘Star Wars: Maul - Shadow Lord’, the Former Sith Returns (New Animated Series Announced)

Minor Maul spoilers below.

I mean Maul has been alive in animation since 2012 when he appeared in The Clone Wars. During that time they do a good job exploring the "somehow". Since then he has gone on to have one of the best character stories in the series.

After his appearance in The Clone Wars he disappears for a time before reappearing in Rebels.

The "disappears for a time" era seems to be when this show will take place. If you watched the live action Solo film his appearance in that film is also from this time period.

It is possible the events or characters from Solo will appear in this series, depending how long the series runs for.
