Skeleton Warriors

Skeleton Warriors, also known as spartus, are monsters who are formed from ancient dragon teeth that are placed in the ground.

History
In Greek mythology, Skeleton Warriors were creatures that were created by planting the teeth of a dragon sacred to Ares. Once the teeth were removed from the beast when killed, one must plant them in black soil and plow the land with a breed of ox that was rumored to have extremely thick armor plating. When this was done, from every tooth in the ground, a warrior clad in full Greek armor would burst from the earth. The most effective way to kill them is to get them fighting each other, for in most cases, attacking and actually killing one would be impossible unless you were a child of Hades. Skeleton warriors would reform, even if they are cut in half or have parts of their body off. Cadmus used them to help him build Thebes after throwing a rock in the midst of them.

The Titan's Curse
While in New Mexico, the Skeleton Warriors attacked Percy, Thalia, Zoë, Grover, and Bianca. When they shot them with arrows, nothing happened. However, when Bianca stabbed one with her Hunter's knife, it erupted into flames, leaving a small pile of ash behind. She was only able to destroy it because she was a child of Hades, although at the time no one knew her parentage.



The group, after Bianca died, encountered more skeletons at the Hoover Dam. Percy was separated from the group after hiding in an elevator that takes him down inside the dam. He then runs into Rachel Elizabeth Dare for the first time and she saves Percy by confusing the skeletons long enough for him to escape back into the elevators. Percy and his friends regroup to try and escape. Thanks to some advice from Athena in disguise and two giant angel statues brought to life by Zeus, the angels give the four of them a ride to San Francisco.

Later, while at camp, Percy figures out that Nico's father was Hades, after the skeletal warriors appear and Nico unintentionally splits the earth to swallow them up. Nico tells Percy that he hates him for not saving his sister and runs away.

The Son of Neptune
Frank Zhang was given a dragon tipped spear, by his newly discovered father Mars, with a golden shaft that could summon a spartus which he named Gray, but he could only summon him three times. He used the first charge to kill a group of Basilisks left by the Gigantes, Polybotes. The second to kill a group of six Laistrygonian Giants, however Gray didn't fully listen to Frank and destroyed the giants instead of distracting them like Frank originally said. The third time, Frank used Gray to protect a group of people from a gryphon attack after their train crashed.

Appearance
The skeletons have transparent gray skin that makes their bones visible and yellow eyes. They wear gray muscle shirts, camo pants, and combat boots. Their clothes shift and look like a uniform at different places and times, they also have the weapons of who or what they are impersonating. They appeared wearing police garb, military outfits, and security guard uniforms.

Trivia

 * It is possible that the magical borders of Camp Half-Blood are unable to keep this type of monster out, as a group of them managed to follow Percy inside the camp before being destroyed by Nico, however it may have something to do with them having Percy's scent.


 * It is also possible that there is a slight variation of them by being born from sabertooth tiger teeth.Variation_of_Spartus.jpeg
