Fidio Aldena is the substitute captain of Italy's FFI team 'Orpheus'. He first appeared in Season 4, Episode 85. He meets Mark when they run into each other and his soccer ball lands on the truck that Mark is running after. He stops the truck and asks for his ball back, while Mark asks the driver if he could borrow the tire in the back. His captain Christofer Nicholes handed over the team on Fidio's hand, and went on travelling and investigating. Fidio manged and leaded his team Orpheus to the semifinals of FFI. He also discovered the darkness of their coach Ray Dark, and helped him to come in the light and devote himself honestly in the world of soccer. He is a best friend of Mark too.
