Ditto Ted in Suikoden IV.
While those are entirely accurate, and Richard especially is one of the most broken characters from any RPG series, this is the General Final Fantasy forum.

Some ones that occur to me off the top of my head:

Fighter from FFI
Ninja from FFT (or Mathematician and Orlandu if you mean "most broken").
Tidus from FFX (despite how much he sucks outside of battle, and he sometimes will leave mid-battle due to the design of the game)
Vaan from FFXII (despite his uselessness in the actual story)
Lightning from FFXIII
