BIO675 specifically requested for a 'big buff three headed Cerberus Girl'. So I give that out as a super form for the three girls.

Abigail, Brittany and Christina Vestmon are a trio of Border Collie girls who sometimes cross paths with the main characters even if they're assigned to a position alongside them. Abigail owns a cafe (where Maria Meiyo works) in Founding Island and is the breadwinner of the trio, Brittany is an amateur artist and a college student, and Christina is a barber. Nothing much to say except they are often separate from each other on a daily basis.

Abigail is often strict towards anyone including her sisters and employees, even outside her job. But she can also be persuasive and supportive
Britanny, a college student with a different course, sometimes meets up with main characters like Timothy due to some of their classes matching up, but would often spend most of her freetime roaming around just to find the best spot for her painting.
Christina mostly spends time inside and outside barbershop, doing her work, slacking off or smoking. She would however do parkour jumps on weekends.

2 Years Later, they would encounter Hypercore who strengthened their interests in muscles by merging the trio with orange crystals forming into their new super form, a big buff beast, stained with yellow glowing marks and black markings, standing at 8'5". Soon to be updated.

Abilities:
1. Acrobatics: The trio can climb and jump onto trees, buildings, etc.; Although Brittany is less skilled in acrobatics.
2. Amateur Martial Arts: They only practice karate for self-defense
3. Super From (2YR): They have the ability to merge into a three-headed beast "Border Cerberus"
4. Muscle Mass Manipulation (2YR): They are given the ability to grow muscles afterwards

Weapons:
They currently don't have main weapons at this point.
