Eevee and Umbreon

Umbreon
Extremely protective and wary of any stranger (Pokémon or human). She's the type to growl softly and bare her fangs if anything gets too close to her young.
Silent, patient, and calculating. She doesn't attack head-on if she can avoid it; she prefers to observe, wait, and act at the right moment.
But she's surprisingly tender with her son: sometimes she licks him behind the ears or gives him little nudges with her head to guide him. When she thinks no one is watching, she even plays with him a little (chasing him among the trees with gentle movements).
She has a strong maternal instinct: she has raised this Eevee alone since it was an egg.

Eevee (the son):
Brave out of ignorance. He wants to explore EVERYTHING: sticking his nose into burrows, chasing Caterpie, climbing fallen logs… although he almost always ends up scared and running back to hide between his mother's legs.
Very affectionate and emotionally dependent. Every time Umbreon moves a few meters away, he starts whimpering softly until she returns.
It is not yet known what its evolution will be, but it already shows glimpses of curiosity about the dark (it stares fascinated at its mother's bright rings at night).
He is playful and a little clumsy. His signature sound is a high-pitched, happy “Vee! Vee!” when he discovers something new.

It's a distrustful umbreon
Its fur is a deep, glossy jet black, as if it absorbs the little light that filters through the trees. The golden rings on its body (forehead, ears, tail, and legs) glow with a faint but intense light, like natural fireflies in the darkness of the forest.
His eyes are a piercing crimson red, full of experience and caution. He is always alert, his ears slightly back as he walks, scanning his surroundings.
Its posture is elegant but tense, like a nocturnal predator. It moves stealthily, almost silently across the dry leaves.
It has some small, barely visible scars on its fur (reminders of past battles defending its young).

The Eevee offspring (wild hatchling):
It's a small Eevee, with the typical warm brown fur, but a little lighter and fluffier because it's a puppy. Its tail is large and fluffy in proportion to its body, and it wags it constantly with excitement.
Her eyes are enormous, a bright golden brown, and full of curiosity and innocence. She's always looking at everything with her mouth slightly open, as if the world were new every day.
It has very large, pointed ears that move in all directions according to the sounds of the forest.
He walks close to his mother, sometimes tripping over roots or leaves because he is distracted looking at butterflies or shiny mushrooms.
