Abilities: They are skilled at creating powerful robotic avatars and have the ability to create destructive, high-tech sound-based attacks.

Personality: The Katayanagi twins are tech-savvy, methodical, and work together seamlessly. They are calm, collected, and often appear cold, but they share a deep bond and operate as a team. Unlike some of the other exes, they seem to have a bit of a more professional and less emotional approach to their relationship with Ramona, though their rivalry with Scott is no less fierce.

Fate: Scott defeats the Katayanagi twins by taking down their giant robot creations. Despite their intimidating tech, they ultimately fall to Scott’s persistence and the band’s determination.

The seventh ex is not necessarily one person but the concept of the League of Evil Exes itself. They represent Ramona’s past, and each member is connected by their desire to control and defeat Scott, ultimately becoming a symbol of Ramona’s unresolved relationships.
