Matilda is Roll's mother, who with her husband Banner, disappeared on Forbidden Island 10 years ago.

She makes her appearance early on, but it is soon revealed that it is not really her, but Yuna who has temporarily taken control of Matilda's body.

It is difficult to really say much about Matilda, seeing as Yuna is the one who is actually interacting with everyone throughout the entire game. In terms of personality, the real Matilda remains a mystery.
