WMG / Grand Unifying Guesses Percy Jackson

Children of Ares

• The Soldier
• Jayne Cobb
• Kyoko Sakura
• Beavis
• Rei Hino
• Butler
• Harry Dresden
  • I would expect Harry to be a grandchild of Hecate, since we know his father, mother, and maternal grandfather, but not his paternal grandparents or his maternal grandmother. This also explains why he's so good at magic at such a young age.
• Wolverine
• Samus Aran
• Maho and Miho Nishizumi
• Ciaphas Cain ^note HERO OF THE IMPERIUM!!!. He inherited Ares's cowardice in the face of stronger opponents, but also his exemplary martial prowess.

Children of Hermes

• The Scout
  • Alternately, his father the Spy.
• Eloise from the children's book series: Wealthy, beautiful, jet setting mom, conspicuously absent father, clear ADHD, possible dyslexia, several possible contenders for protectors. And she lives at the Plaza Hotel.
• Ami.
• Sonic the Hedgehog ^note Through shapeshifting at a drunken revel.
• Catwoman

• Eric Cartman, he inherited charisma…fortunately, that was all he inherited.
• Pinkie Pie

Children of Hades

• The Medic
• Kenny McCormick
• Homura Akemi
• Setsuna
• The Perfect of Paragon
• One of the Joestar's ancestors from Jojos Bizarre Adventure, not because they have any special powers, but because Zeus and Poseidon hate it when they get on planes or boats.

Children of Athena

• Dell Conagher (The Engineer)
  • Huh, I always thought of him to be descended from Hephaestus…

• Lucrezia Mongfish ^Explanation: (Her command voice is just a more specialized version of charmspeaking. Think about it: yelling "Stop! I am your creator!" virtually never works out well for Sparks, so how does Lucrezia make it work on her creations? She's cheating, that's why! Plus, being supernaturally beautiful explains how she convinced Bill to wed her.)
• Erika Kurumi

Children of Poseidon

• Sayaka Miki
• Michiru Kaioh
• Jack Sparrow
  • Sorry, CAPTAIN Jack Sparrow
