Gaelion

Gaelion (ガエリオン) is a dragon hatched and raised by Naofumi. He is named after Wyndia's adoptive father, Gaelion, who was killed by the Sword Hero.

Appearance
Gaelion appears to be a small orange dragon, he has tiny wings on his back and has no scales. He has two horns and has a fat tail. However, Gaelion has the ability to shift his size, changing into a more adult form better suited to combat than the relatively small infantile body, and back into his small dragon size when preferred.

Personality
Gaelion suffers something of a split personality disorder as a consequence of eating a Dragon Emperor core. However, as Gaelion grows older his multiple personalities will gradually merge together.

The first and most dominant personality is that of the infantile body, the original inhabitant of the body. This personality deeply loves Naofumi as a parental figure and has an extremely playful personality playing with Wyndia and desiring to play with Naofumi.

The second, less often seen personality is that of the Old Gaelion for which the infant was named for, this personality shows a degree of wisdom rarely seen among his kind and is usually defined by his love for his adoptive daughter Wyndia and a lingering grudge against Ren Amaki for killing him. Eventually, after seeing his daughter being taken care of by the Shield Hero in his village, he agrees to lend a hand. He prefers to remain silent when in the presence of Wyndia, as to let her live unknowing of the effects of the dragon core.

Volume 12
Gaelion's egg was gifted to Naofumi anonymously, along with a large amount of weapons and armors, it was speculated that it was either from Siltvelt or Shieldfreeden that gifted him the dragon egg. The decision was made for Naofumi to raise the egg and as such over the next few days is cared for by Naofumi up until it hatches at which point in time he assigns his slave Wyndia and new personal alchemist Rat to care for the infantile dragon.

The dragon spent several days playing pranks on Naofumi hoping to get his attention until he allowed the dragon to stay in his room with him, at which point in time the dragon ate the composite dragon core from Naofumi's armor and the Dragon Core took possession of the young dragon's body.

Once the Old Gaelion took control of the child's body, it escaped back to its old nest. Naofumi and company decided to follow him, as both Filo and Naofumi started suffering consequences, due to pieces of the dragon core existing on Filo's body and inside the shield. Upon reaching the nest, close by the Eastern Village that once was plagued by the rotting body of the Old Gaelion.

They encounter Gaelion, now having changed into a "Wrath Dragon," due being linked to Naofumi's Shield of Wrath through the core piece inside the shield, sapping power from it.

After regaining his senses, thanks to Wyndia's intervention, Old Gaelion ends up being superseded by the Demon Dragon Core portion that was part of the composite core. During the fight, the body of the child Gaelion is expelled from the Wrath Dragon's body, with the core from the Demon Dragon becoming separated from the core of Old Gaelion.

Once the fight with the Demon Dragon has concluded, Old Gaelion called for Naofumi, presenting himself as "The Weakest of the Dragon Emperors," and proceeds to apologize for the entire problem brought up by both himself and the Demon Dragon. He then asks Naofumi two favors, to keep looking for Wyndia, and to not reveal to her daughter that he is kind of alive, despite her having finally accepted his death.

Finally, Old Gaelion promises to help Naofumi whilst he raises child Gaelion and his personality eventually merges with the child dragon's.
