Despite his decent amount of appearances, Galacta Knight's true personality and intentions are not well-known. While he was feared for his immense power, Galacta Knight has never been stated to be explicitly evil, even though he may potentially be violent and destructive. However, it is stated by Star Dream that he may destroy a nearby planet or two for seemingly no reason when brought to the current time, and in Super Kirby Clash, his Light form quest description states that the fate of the world is at risk, which appear to portray him in a villainous matter. Given that he was a hero, it could be possible that he used to be courageous and good-natured, although it is unknown what would have changed him to his current state if this were to be the case. Regardless, Galacta Knight is currently known to not be benevolent, and will use his powers to usually attack anyone within his vicinity without mercy, including those who summon him.
