The Egg Spear is an object that appears in the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing. They are lance-like weapons used primarily by the Egg Pawns of the Eggman Empire.
Despite its name, the Egg Spears resemble the stereotypical lance more than a spear. They are quite long by comparison, easily over twice an Egg Pawn's height in length. Possessing a white and orange cone-shaped head with a sharp orange point, they each have a large, thick and round orange vamplate and a thin orange and black grip.
The Fate of Dr. Eggman
When Sonic snuck onboard an Egg Fleet battlecruiser, he was found by Neo Metal Sonic, who had a number of Egg Paws with Egg Spears surround Sonic. Sonic, however, managed to disarm one of them and use its Egg Spear to spin around with it in hand, defeating the Egg Pawns surrounding him. He then threw it at a nearby artillery cannon and obliterated it.
