It's a power-leveler's wet dream. Disgaea level cap is 9,999, to get the best stats you need to have reincarnated to save up thousands of levels and then done the best reincarnation again at level 9,999 and then make your way up to 9,999 again, plus you can level up the weapons to level 200 and give them specialists to make them really uber.

The main plotline itself can be finished at level 80-ish.

Several extra bosses, however, do have stats that obscenely high, especially with bills passed to make enemies stronger and what have you.
