Scorponok (BW)

Scorponok was a Predacon scorpion seen in the first season of Beast Wars. Scorponok was portrayed as blindly loyal to Megatron(comparable to the manner in which G1 Cyclonus was loyal to Galvatron), sometimes stupid but also a creative genius, developing many inventions.

Scorponok fell into the lava underneath the Darkside at the beginning of season 2 along with Terrorsaur. Both were never seen again, and presumed dead.
