Radaxian Royal Family

The Radaxian Royal Family are one of two ruling nations on Planet Aries, and the family that Alex Kidd and Pit Pot's star Egle are a part of.

Royal Family
King Thunder - Father of Alex and Egle. He was the ruling monarch until Janken the Great invaded and began turning the people of the land into stone. After defeating Janken and saving Egle, Patricia and Lora, Alex is disheartened to hear his father is still missing and sets out to find him.

Hearing he'd last been seen on Planet Paper-Rock, the home planet of Janken, Gooseka, Chokkina and Parpalin, Alex believes King Thunder has been kidnapped by the current Paper-Rock ruler, Ashra. Upon defeating Ashra he discovers that King Thunder was not only there of his own accord, but was using Ashra as a servant. King Thunder shows up only in Alex Kidd in the Enchanted Castle's finale.

Queen Patricia - Mother of Alex and Egle. Queen Patricia was fortunate in that when Janken and his army arrived she had been taken to a safe place by the royal guards. Princess Lora informs Alex of her safety when he rescues her. Patricia appears on screen in Alex Kidd BMX Trial only. It is not known why King Thunder didn't take Patricia with him to Paper-Rock.

Prince Egle - Alex's elder brother(although they could possibly be twins). He originally was a knight and hero in his own right, rescuing Princess Lora from a sorceror who had kidnapped her and placed her in Pit Pot Tower. Egle, wielding a magic hammer charged into the castle, defeated the monsters within, broke the curse of Lora, sealed the magic of the sorceror and asked Lora for her hand in marriage. She said yes. After Alex rescues Egle and defeats Janken, Egle takes up the throne as the ruling monarch of Radaxian in his father's absence.

Alex Kidd - Younger prince of the Radaxian family, Alex was kidnapped by some villains at a young age and thought dead. Alex was raised in the mountains by St. Nurari for seven years as his own son, teaching Alex the martial art of Shellcore which prepared him for the battles ahead.

Alex Kidd is the main protagonist of the franchise, and upon discovering his past he goes out to save his blood relatives from Janken and his army.

Princess Lora - Egle's beloved fiancee. She has had the misfortune of being kidnapped twice now, once by a Sorceror and again by Janken. Despite this she shows suprising backbone, having made sure Queen Patricia was out of harms way before being captured by Janken's army. Once Egle becomes King, she rules alongside him. She appears in Alex Kidd in Miracle World, Alex Kidd BMX Trial and Alex Kidd in Miracle World DX.

Alex's Girlfriend - Technically hasn't married into the family yet, Alex's Girlfriend is assumed to be a native of Shinobi World. Hanzo, a dark ninja who was banished 100,000 years ago returns with his power drained. He kidnaps Alex's Girlfriend in order to perform a ritual and restore his power to it's former glory with his eyes on taking over Shinobi World. Alex saves her in the end, and they continue their date. She appears as a scorecard girl in the Switch version of Sega Ages, and also in Sega Ages: Columns II as an unlockable scorecard girl in the jewel case alongside Stella.

Halifax Kidd - Only mentioned in the manual for Alex Kidd: The Lost Stars, Halifax Kidd was Alex's ancestor, and a prince of Radaxian from 5,000 years ago. Halifax Kidd had previously defeated Ziggurat when he had attempted to steal the constellations from Planet Aries back then. Ziggurat swore he would some day return to steal the constellations once more. Nothing is known about Halifax aside from his name and his victory.

Allies
St. Nurari, a local hermit and martial arts mentor, saved Alex and took him in as his own son, raising him in the mountains and teaching him Shellcore, a martial art that allows the users limbs to grow giving them enough power to shatter rock with their bare fists. He reveals Alex's true bloodline to him in Alex Kidd in Miracle World.

The Radaxian Royal Guards - A collection of Royal Guards that appear only in Alex Kidd in Miracle World DX. They are trying to free Egle and Lora, and can be assumed to be the ones who helped get Queen Patricia to safety. The Captain hands Alex Kidd, the only clue they found; Egle's Magic Hammer.

King High Stone - Ruler of Nibana, Radaxian's neighbouring country. King High Stone is on good terms with the Radaxian royal family, and aids Alex by giving him the Hirotta Stone, a vital keystone to obtain the Golden Crown and reverse the petrification Janken had unleashed upon the people. Unlike King Thunder, High Stone refused to leave his castle when Janken invaded.

Stella - It is unknown exactly whether Stella is a member of Radaxian or the neighbouring kingdom of Nibana that King High Stone rules over, but she appears to be a close friend of Alex, who aids him in his quest to collect the Miracle Balls in Alex Kidd: The Lost Stars (arcade version) and stop Ziggurat, making her only one of three playable characters in the series(the others being Alex and Egle if Pit Pot is counted). She also appears in Sega Ages as a scorecard girl and in Sega Ages: Columns II as an unlockable scorecard girl alongside Alex's Girlfriend.

Daleda - An ancient wizard, who much like Halifax Kidd only appears in the manual of Alex Kidd: The Lost Stars. He aids Alex and Stella by informing them of what has happened and then opening up a magic doorway between worlds, to the world Ziggurat resides in.

Ashra - Ashra is technically an ally of the Radaxian Royal Family. He is said to be King Thunder's servant, but actively fights Alex when he arrives at his castle. Upon the misunderstanding being cleared up, it is said Ashra as well as the people of Planet Paper-Rock become friends and allies with the people of Aries.
