Belldandy is unflinchingly kind, patient, and warm, not only to Keiichi but to everyone, without exception. However, this does not mean that she is to be taken lightly; Belldandy is licensed as a goddess first-class, unlimited, and as such is highly skilled. Her power is so great, in fact, that she is required to wear a special earring on her left ear which constantly seals the full brunt of her magical strength. The only time at which she has ever revealed her true strength is during the Lord of Terror arc. At the end of this arc, Belldandy completely reconstructed their home from rubble, mentioning that doing so only took one ten-millionth of her power.
Belldandy's capacities and talents are diverse, whether magical or worldly. Not only can she change the appearance of her clothing and levitate (and, by extension, fly) as all full-fledged goddesses are expected to, but she can also teleport through mirrors, speak to and understand animals, "see" people's emotions as auras, heal minor wounds by speeding metabolism, and "speak" to machines. Furthermore, she is a superb cook, and her singing skills are held to be the best in the heavens. She is also incapable of getting drunk on alcoholic drinks, but instead gets drunk with soda (it has to be noted, however, that she's a complete lightweight in this regard. One sip is enough to send her in a drunken rampage -- although given her personality, "rampage" takes an entirely different, but no less destructive, meaning). In addition, she is also the top broom racer in heaven, the only one that could rival her is Welsper from hell or Hild the Daimakaichou herself.
