Franklin, Franky

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.

In the last war between Ostania and Westalis, Franky was drafted as a soldier, but attempted to desert. During his attempt to escape, he met "Roland Spoofy", a Westalis soldier who would later become known as Agent Twilight. He's once dreamed of making the world a better place with his inventions, as well as getting money from patents.
