Roxy Rocket, who started out as a character in the Batman Adventures Annual #1 before appearing in Batman: The Animated Series and Superman: The Animated Series, finally gets an action figure of her own along with her rocket speeder.
Hot Toys has an entire line of 1/6 scale Batman movie collectibles. This one of Michael Keaton in Batman Returns is the best IMO. The movies were goofier, but Keaton was such a better Batman than Christian Bale ever could dream of being.
There’s also a two-figure set featuring Batman and the Bruce Wayne figure. These figures are very expensive, but the detail that goes into them certainly justifies the cost.
