It is Conan O'Brian

The Flaming C
 On the program Conan, Conan O'Brien visited Bruce Timm during one of his segments and they developed a super hero named the Flaming C. However, on several occasions, their original creation would be animated in preexisting sequences from Young Justice using the voice acting of whichever character Flaming C was placed over. These scenes were taken from "Fireworks", "Welcome to Happy Harbor", "Schooled",  and "Denial".
