Im very sorry if someone made a theory like this before but what if the kraata is krana dipped in protodermis and the bohrok kal turn into the rahkshi

No, the rahkshi is a totally diff creature than the bohrok or bohrok-kal. The kraata looks like a slug in the trailer, and I think its totally diff to.

Well i doubt that. I don't think they'll go back to the protodermis poll a second time. that idea has already been used.
Thats a very unique theory though.......
