|Quote||"Monsters, magic books.. doesn't it all seem a bit ominous?"|
|Voice Actor||Erin Mathews|
Her father, the king, was originally unsure about her becoming a knight, but has since warmed up to it.
Macy is very dedicated to being a knight. She wants to protect Knighton and she wants to prove to her father that she is a great fighter. She is mad that he won’t recognize her and she takes it out on every monster she can swing her power mace at. She loves going into battle with her friends, which always makes her father very nervous. Oh, did I mention her father is King Halbert and Macy is also a princess of the realm?
Macy struggled with her parents believing that she didn't have what it took to become a knight, and vowed to prove them wrong. It is this drive that made her a valuable member of the team. It is revealed in "Fright Knight" that Macy has a fear of being the pretty little princess her father wants her to be, with no possible chance of becoming a true knight.
- Macy is the only female Nexo Knight.
- Her name is a pun on the word "mace". She coincidentally uses a mace as her weapon.
- Her last name comes from the weapon "halberd", a spear and battle axe combination weapon.
- Macy's role was similar to Nya and Kai from Lego Ninjago.
- Macy was a princess, but she didn't want others treat her as a princess, but a good knight. Nya was a girl ninja, but she didn't want others treat her as a girl only, but as a skillful ninja.
- Macy liked to make a video blog about her life, as shown in A Day in the Life of Princess Macy. Likewise, Kai indulged in his fame the most out of all of the Ninja.
