The other Elite Makuta
Brotherhood of Makuta/ZFT
Bonecrusher was created 99,450 years ago in order to drive the Vrai out of the Matoran Universe along with Blackout, Starscream, Barricade and Brawl. He hates that. After this was accomplished, Barricade, Brawl and Bonecrusher were placed in stasis pods (which he hated). When Blackout created Darkmount, he took the pods with him, and later ordered Malygos to retrieve a crystal, hidden by the Great Beings on a distant planet, which would reawaken the Makuta. He hated that, but not as much as the former. That happened. Then, Ynot, the Makuta Anima and The Fallen attacked. He hated that. Bonecrusher attacked Kurenitsu. He hates Kurenitsu. Now it turns out he can't even destroy a few (hundred thousand) flowers. Guess what?
- In the Eternal Universe, Bonecrusher was called "Bonesmasher". He arrived in the OU with his companion Starscreech to enforce the Universe-Travelling Restriction Act 1999 upon Shockwave and Yon. However, Shockwave simply shot and killed him before teleporting away again. Starscreech sighed, and carried Bonesmasher's lifeless body back to the EU.
