@hewhoknowsall:
thats cuz they are all weak... maybe except anakin solo.
but we never got to see his full power cuz he died
and shimi isn't even a force sensitive.
and isn't Cade stronger than Kol???
edit again...: neither Ben nor Leia have developed their powers (Leia moreso than Ben.. but well idk since Leia beat Alema Rar) who also sucked
I would place Cade over Jaina... and Kol, as he seemed to be the Grandmaster of the Jedi Order in the Legacy era, not that has been confirmed.
As for why Jaina hasn't developed as strongly as the others of her family tree... I'm not sure. I would like, at some point, for there to be a powerful female Skywalker. Leia and Jaina are not good representations of the Skywalker lineage.
And haha, Shmi is not worth mentioning due to her lack of Force sensitivity.
