I recently saw the movie Moana and I highly recommend it to everyone. Moana is from the Island of Motu-Nui which sound a lot like the island of Mata-Nui. In fact, there are a quite a few Non-Bionicle people calling it "Mata Nui" and don't even realize they are making a Bionicle joke.
Anyway, one thing I really loved about the movie was how Maui uses his hook. In 2001 Gali's hooks seemed a little out of place, but after seeing Maui I think Gali could look awesome with her Hooks in Gen 3.
