The Green Hornet/WMG

Kato either is or is related to Short Round from Indiana Jones and The Temple of Doom.

 * Now hear me out, the only problem is the time, but they are both Chinese and both show martial arts expertise.
 * Short Round was in his preteens when he was with Indy in 1935, and Kato appeared to be in his late 20s in 2011, so probably 2 or 3 generations away from short round.
 * Note which work we're talking about -- the radio show which ran from 1936 to 1952. The 2011 movie is covered by a different page entirely.  Given that the radio show started in 1936 with an adult Kato, though, it's unlikely he's Short Round.
