Richard Harkin is a fictitious character from the YouTube comedy series The Lenny Leggo Show. He is a returning main character from the now discontinued series "The Lenny Lego Show", in which he was killed off during the seventh season of the show, notably due to lack of character and public interest. However, he will be reincarnated into the new series as "Richard Harkin". His character, like in "Lego Show", will be that of a scientist, and will even be further explored in this series than it was in the last. His character will also be employed with the fictitious company Smith & Uncle.

Presently, it is undetermined if he will become a main (primary) character, or a secondary one. However, because he was a primary character in the prototype series, he will most likely return as a main character in The Lenny Leggo Show as well. His introduction will come sometime during the show's first season.
