15. Trials of the Demon!

Guest Stars – Teaser: The Flash (Jay Garrick), Episode: Etrigan the Demon, Sherlock Holmes

For our Halloween episode, we have a solid creepfest that features my favorite recurring villain, the Gentleman Ghost!!

In this episode, someone has been sucking the souls out of women in Victorian London, and Sherlock Holmes is on the case. Yes, that Sherlock Holmes. He begins to investigate, but when the townsfolk find their suspect, the strange and mysterious Jason Blood, Holmes isn’t quite convinced. He discovers that Blood has been attempting to summon help from the future and has completed the ritual bringing back…Batman!

Bats and Holmes free Blood, who transforms into his alternate identity of Etrigan the Demon. The trio goes off to find the true culprit, Gentleman Jim Craddock, who is trying to make a deal with the demon Asteroth for immortality. What ensues is a fun Halloweeny time that gives us a riff on the amazing Gotham by Gaslight. And having Gentleman Ghost be Jack the Ripper so Sherlock Holmes and Batman can fight him is literally everything I’ve ever wanted out of a superhero cartoon.

Verdict: Great!
