Why do red Saber and blue Saber look so alike?


On the surface, red Saber (from _Fate/Extra_ ) and blue Saber (from _Fate/Stay
Night_ ) look almost identical.

Was it ever explained why they look so similar?

What noticeable differences do the two have, aside from their abilities and
attire?

Saber is extremely popular character. They are just "milking franchise" with
character that looks similar to the original. And by having little different
personality, they make sure they gain interest of more people other than fans
of original Saber.
