Interesting... I'll just do someone from off the top of my head. Uh... Red Savarin from Solatorobo: Red the Hunter (aka the game with furries that is less popular than it should be).
Theseus seems like a suitable Persona. From a combat perspective, Red is very resourceful, using his glorified forklift robot and the environment (which includes enemy attacks) to defeat other robots, some of which are literal tanks. Theseus was resourceful as well, using his enemies' strengths against him rather than relying on his subpar physical abilities (such as when he tricked a certain person into trapping themselves into a bed rather than Theseus himself, killing a bandit by tricking them into giving him their club, etc.). From a personality perspective, while both Red and Theseus are brave (and, in their stories, discover their true heritage, with Red being a [Spoiler] and Theseus being a demigod), Red is very impulsive and can not think things through at times. If I remember correctly, Theseus's fatal flaw was forgetfulness. He was so caught up in his victory against the minotaur that he forgot to put up a sail, causing his faux father to kill himself, bla bla bla Aegean sea, you get the picture.
And I spent way too much time on this.
