Of course, Animorphs belongs to K.A. Applegate.
Safirya-Iskilion-Simnil

Female
Personality: Mischievous, but very smart. Seen as something of an oddball among other andalites but that is forgiven because she is one of the most famous Estreen-Morph artists. She is obsessed with the possibilities of morphing technology. When she finds humans, she is fascinated by how their plain bodies have so much to change, especially the tail. Her father was a soldier, killed in action. Her mother has a chronic illness that Safirya believes can be cured by morphing. This is why she has made the study of the morphing tech her life’s work. She’s rather flirty with other andalites which can get her into trouble. Involved with the furry community eventually.

Morphs:
Vargil
I'm seeing something elephant sized. But long. Maybe 20 feet long. Six legs. Long tail. Stinger on the end with a neurotoxin. Chameleon like ability to change scale color. Head sort of like a dragon on a long neck with fins for ears and a large ruff going from head to tail.

Kafit Bird

Kronreer.
Feline about the size of a tiger, no fur, skin sort of like a dolphin. Blue with purple stripes. Six legs, long tail face is a cross between a wolf and a lion. Very sleek. Sonic attack

Tech with her:
Enhanced fighter with sophisticated cloaking tech that hides heat signature and visual signature
Escafil Device
Veermak: Crystal that Enhances the animal side of the brain while in morph. Uses it to study.

What she’s studied:
Morphing obviously, studied under Escafil herself
