question:
Wizard:  Leonardo , the leader of the team is smart , strategic with a strong sense of honor .
Boomstick: Too bad he traded his sense of humor for that sense of honor ! This guy always means serious business ! His weapon of choice is the ninjaken swords : Shorter , sturdier and straighter than an ordinary katana , and designed for swift deadly strikes ! Out of all the Turtles ' weapons , the ninjaken is the only one specifically designed to murder people ! What 's better than one ninjaken ? _ Two _ , damn it !
Wizard: In many timelines , Leonardo 's the one who ultimately defeats the Shredder , though always with plenty of help . As leader , he is usually the one with a plan . He spends most of his time training his body and mind under his Master Splinter 's instruction and follows Bushido , a strict Samurai code of honor and duty . At one point , he even fought and killed a sort of physical embodiment of the Devil .
Boomstick: Giving Keanu Reeves a much needed break !
Wizard: However , Leonardo finds it difficult to accept failure . Should things go horribly wrong , his concentration can quickly slip away from him , leaving him sloppy and imprecise .
Boomstick: Leo does n't like to lose .
answer:
REFERENCE ninjaken
