|Voice Actor||Tia Texada (english)|
Isabel was first seen when Duncan was being introduced to her science class. She told him to sit by Kenny since he did not have a partner.
Isabel is a smart, spunky, and outgoing girl. She has a one-sided crush on Duncan, despite him having his eyes already set on Jenna.
A unique trait that Isabel has is she is a huge Kaiju fangirl, therefore having expert knowledge on them, making her a useful ally to Duncan.
She also spends some of her time reading MEGTAF reports on Kaiju.
