Actually when you think about Bleach has many characters: 13 captains(past and present), 13 lieutenant(past and present), the zero squad, bounts, fulbringers, and numerous plus, hollows and arrancars.

The stern ritters have an alphabet associated with there powers so it's possible that they maybe 26 of them.

Then there are some many characters that made only one appearance, so it should be expected that some characters look alike.
