In the recent trailer that Cartoon Network released to showcase the return of DC Nation to its regular weekend time, Hal Jordan was shown overcome with greed from the power of the Orange Power Battery. This led to fan speculation that Larfleeze would soon be making his appearance on the show.
Now website Blog of Oa is confirming that Larfleeze will indeed be in a future episode by announcing that the character will be voiced by veteran voice actor Dee Bradley Baker. Baker has voiced a host of characters that includes such notable roles as Olmec in the Nickolodean game show Legends of the Hidden Temple, Appa and Momo in Avatar: The Last Airbender, Captain Rex in Star Wars: The Clone Wars and Hal Jordan in Young Justice.
Show Producer Giancarlo Volpe has confirmed that Baker will indeed voice the character of Larfleeze via twitter.
