Last year, I made recordings and an all-in-one DVD of three different holiday-themed comic book cartoons. I'd forgotten I had this, stumbled upon it, and popped it in during Christmas Eve festivities. Glad I did.
(And, yes, there's a theme here.)
Powerpuff Girls: Twas the Fight Before Christmas
I miss this show. Tom Kenny is an amazing voice talent. The special has Princess Morebucks, who is one of my favorite baddies to hate -- and she's a Powerpuff girl? And Santa takes Christmas away from everyone? And then he's ... had ... enough!?
Good stuff.
Justice League ("Comfort and Joy")
This was a great series, and I'd argue better than its follow-on Unlimited incarnation.
This holiday one shot (most episodes were part of 2- or 3-episode arcs) is fun, has a lot of heart, and shows some (mostly) non-combatitive vignette moments of key members of the team. Superman/Clark and Martian Manhunter/J'onn visit Smallville. Green Lantern/Jon Stewart and Hawkgirl/Shayera have a superhero version of a snowball fight (then are off to an alien bar for a decidedly different holiday tradition). The Flash/Wally West and Ultra-Humanite end up in a battle that winds up well for everyone (including some orphans).
Batman: The Animated Series ("Holiday Knights")
Perhaps my favorite all-time cartoon, this holiday one-shot was one of the last episodes of the 1990s TV series. It has three great, different stories that have Bruce Timm's trademark "I get it" take on each character. The first story has Harley Quinn and Poison Ivy kidnap Bruce Wayne and put him under their control, using his money for a huge Christmas shopping spree. In the second story, Batgirl takes on Clayface in a Gotham Department Store during the holiday shopping rush. , Finally, Batman and Robin take on the Joker, who's (understandably) trying to kill all the people at Gotham City's New Year's Eve celebration. Great, solid acting and good story throughout.
I need to add the "Christmas With The Joker" episode to this collection. That episode has Mark Hamill (The Joker) in top form. And he sings a special version of "Jingle Bells".
