  • Created the original Power Suit for Samus Aran, an almost universally modular suit that combined both biotechnology and Chozo Magic. (Intellect feat)
  • Determined that the pirates had been genetically programmed to follow a strong leader and took control of the entirety of the Space Pirates organization the literal moment they had arrived on Zebes. (Intellect feat)
  • Was the 'center point' of the entire Chozo civilization for a century, in other words, she analyzed and determined the most efficient methods for dealing with nearly everything for their race. (Intellect feat)
    • Would have eventually done so for the entire Milky Way Galaxy had she not gone evil.
