|Real name:||Basil Karlo|
|Aliases:||Clayface, Karlo, Basil, and Superman.|
|Portrayed by:||Wallace Langham|
The fourth season episode "Clayfaces" introduces Basil Karlo (in his first actual appearance outside the comics) as the series' Clayface II, who is voiced by Wallace Langham and later by Lex Lang.
Basil Karlo is shown to be a nerdy, unattractive and untalented actor. He is seen repeatedly turned down in auditions for a dog food commercial when he hears that Clayface is about to be cured. Basil Karlo breaks into Wayne Tech and drinks a refined, purified sample of Clayface-formula. This successfully turns him into Clayface II. He assumes a handsome form, believing his rejection was the result of his poor appearance, but ends being rejected once again for a dog-food commercial thanks to his lousy acting, he snaps and uses his claylike superpowers to attack the people who rejected him. At first, he believes this incident would be the death of his career, but he then sees that being a super-villain has given him the media's attention (despite the fact that it also made him infamous), covered on nearly every channel (he stops on the last channel, which shows his previous movie, The Revenge Of The Atomic Clone). After a battle with Batman, Robin, and Clayface, Clayface II is injected with Clayface-antidote, seemingly restoring him to normal. However, the episode's final scene shows that Clayface II still has his superpowers. He reappears in "The Batman/Superman Story, Part One" where he, along with Bane and Mr. Freeze, is in the employ of Black Mask, who has teamed up with Lex Luthor and kidnapped Lois Lane as bait for a trap to lure in Superman.
PowersEditLike the previous Clayface, Basil Karlo is capable of shape-shifting. While a terrible actor, the refined mutagen, allowed Karlo to be much more powerful then his predecessor. His shape-changing is of higher quality and he can even produce more complex weapons, such a rotating drill. His larger size also gives him greater strength as well.
Despite being able to become anyone Karlo was a terrible actor, it is easy to see through his deception when he tries to impersonate someone.
One of Clayfaces known weakness is to extreme cold temperature. He is easily frozen when in combat.
In the comics, Basil Karlo was the original Clayface. Other people that adopted the alias of Clayface in the comics includes Matt Hagen, Preston Payne, Sondra Fuller, Cassius "Clay" Payne, Dr. Peter Malley, Todd Russell, and Johnny Williams (Ethan Bennett was created exclusively for the show).
