"Being a Keyblade Master is all I dreamed about."
"I know. You, me and ven all share the same dream."
"You will pay, Xehanort! Was my Master—no, my father, Eraqus not enough for you? Leave my friends alone!"
"You have to be strong. Strength of heart will carry you through the hardest of trials."
Terra's calm and cool exterior hides a heart that would fight for his friends, yet he is constantly tempted by the darkness, similarly to Riku. Oblivious to the fact that Master Xehanort is attempting to seduce him into darkness, he is forced to doubt those most special to him, and only realizes his wrong-doings after they occur. While not gullible, Terra can be overly trusting, which most villains use to their advantage, leading to his misadventures. His experiences with darkness bring a negative vibe to him, but Terra holds his bond with Ventus and Aqua in high esteem, willing to fight for them despite his ties to the darkness, wishing to help them long after his possession. This is seen with the new Xehanort, Xemnas, and the Lingering Will, each of which demonstrating instances of Terra's faded consciousness acting on Ventus' and Aqua's behalf. He also holds Master Eraqus in high regard, viewing him as a surrogate father, which he proclaims to Xehanort; for example, he cries at Eraqus' apparent demise and is visibly happy when he reveals that Eraqus has "set foot into" his heart.
