Franky Franklin is an informant who seemingly works at a tobacco store and presumably works for Loid Forger's agency. He gets information regarding Eden Academy's exam and Anya Forger's past records for Loid Forger.

Franky is a kind person willing to help Loid out when he's in a pinch even though the danger is high. He frequently warns Loid Forger not to get too close to other people in their line of work. He frequently falls in love with other women but his love life typically fails due to lack of mutual interest or they are already with someone else. He's rather money-driven as he is willing to perform favors for Loid as long as Loid promises to give him material goods, even though he was previously reluctant to do so or even if the situation is extremely dangerous.
