keep calling this headcanon when all it meant was (no sword no df kaku) is slightly stronger than (no df jyabura).
There is a whole canon cover story about how CP-9 ended, by your logic Mr.2 is stronger than Mr.1 because he appeared in the story later.
Jabra was the only CP-9 member who could move and use Tekkai at the same time, does that mean something to you?
