In LPOTN Kaia was supposed to reval as half nindroid yet the story got cut because kaia didn't suit as nindroid

"me and orano was pretty close siblings.we had everything what ever we needed.but one day our house caught on fire.and we all tried escape from house but me and my mother couldn't get out and died.but my brother...recreated me meanwhile our father Neuro was in tournament.. Orano was using parts what was left from me and little bit  technology making me  nindroid.but still an human.we get well along back than .we did find lot of thinks that  ninja or some others destroyed.we fixed realm crystal what with we both get know some people ninja saw before AND sword of sanctuary and even helped build the bounty.But one day we tried find lot of stuff and think what catched orano eye was red glowing diamond.none of us have seen that before and orano picked it up because he didn't know it was evil but...his eyes started little bit glowing red.i didn't know it did something to him before.and orano started act strange.so with my own safety i took silver metal and made fanblade out of it.and i caught him talking with the red diamond "i will find Kai.and make sure do find both spinjitzu scroll.i just have use my power to take her under my control"so yeah i lied about the betrayer part but i run away..and found out how to stop this  working.powertaker gem could help but i am not sure how.so yeah he wasn't always evil and i hope whatever we have to do with powertaker gem.we must not try kill him...it's not his fault it's this stupid red diamond fault what happened.i try my best to not hurt him.
i know there still good in him... "

-flashback end-

And pixal looked at kaia and asked"what happened to you're mother?" And kaia answers"orano didn't find her parts these were completely gone" and pixal looking at kaia with sad face and says"i am sorry whatever happend to you.i promise i will try to not kill him"

An old concept of half nindroid Kaia:
