I've never thought that Riinengan was a merger between Sharingan and Byakugan...but since Jiraiya said that Riinengan was the fist eye technique or something like that I believe that Sharingan and riinengan are "descendants" of the riinengan...they're the evolution of the riinengan.I can't see how Riinengan is the strongest of eye techniques since someone with a EMS is ordering around someone with the Riinengan.
The mangekyou sharingan has different patterns on each user but xept Kishi no one knows why and if there are differences in power.IDK maybe the more complicated the pattern the stronger the sharingan?Kakashi had the most simple pattern and he has the weakest..but that is just something that popped up in my head now so it's prolly wrong!xD
