In the next ten years, The D used the destiny-altering powers of the Light of Destruction to reign as the champion of the [[Pro League]], while Aster grows into a strong Duelist who ranks high in the League himself despite only being fifteen. Aster had vowed to find his father's murderer, and Duels with "Destiny Heroes" his father created. He knew that when he found "Plasma", he would find his father's murder. The D eventually invited Aster to his yacht, and there he revealed the truth and Dueled Aster. In addition to his winning record in the Pro League, The D had competed in numerous underground Duels, where he had used "Plasma" to imprison the souls of countless Duelists. The first victim was Mr. Phoenix himself, who briefly communicated with Aster during the Duel. He urged his son to win the Duel, which would release the souls of the Duelists and purify the card. After some hesitation, Aster did so, thwarting The D's strategy via "[[Destiny Hero - Dark Angel (anime)|Destiny Hero - Dark Angel]]" and attacking with "[[Destiny Hero - Celestial (anime)|Destiny Hero - Celestial]]" to destroy "Plasma" and win the Duel. With this, the soul of Mr. Phoenix was finally able to rest in peace.

Mr. Phoenix was a card designer. Due to this fact, [[Tragoedia (character)|Tragoedia]] chose him as a vessel. Tragoedia continued to raise Phoenix's son [[Aster Phoenix (manga)|Aster]] while possessing him, with Aster none the wiser. While possessing Phoenix, Tragoedia created the "[[Legendary Planet]]s", which he imbued with the power to sap small amounts of energy from Duelists who faced them. He also created the cards he would use in his [[Tragoedia (character)#Deck|personal]] Deck during this time.<ref name="chp60">{{chapter|Yu-Gi-Oh! GX|60|ref}}</ref> When Phoenix's use was at its end, Tragoedia called for a meeting with [[Principal MacKenzie]] of the American Duel Academy. During this meeting in MacKenzie's office, Tragoedia released his hold on Phoenix and possessed MacKenzie instead, killing Phoenix in the process and taking the "Legendary Planets" from him.<ref name="chp40">{{chapter|Yu-Gi-Oh! GX|40|ref}}</ref> Through MacKenzie, Tragoedia kept in contact with Aster, with Aster still unaware of his existence. He gave Aster "{{Manga[[The Grand Jupiter (manga)|The Grand Jupiter}}]]" from the "Legendary Planet" series, telling him that his father would have wanted him to have it when he was mature enough.<ref name="chp54">{{chapter|Yu-Gi-Oh!
