Fennekin and Vulpix

Fennekin:
It's usually a curious, intelligent, and somewhat proud Pokémon. It enjoys learning and practicing fire-type moves, and has a slightly tsundere personality: it may seem aloof or arrogant at first, but it's actually loyal and affectionate towards its trainers and companions.
In this wounded state: His pride is wounded by pain and vulnerability. He tries to maintain a serious or stoic expression despite the tear, as if he doesn't want to show weakness. However, he approaches Vulpix seeking (and offering) comfort. He is the "older" of the duo in this image, acting with more emotional restraint, but clearly suffering. His intelligence makes him aware of the danger, so he is probably thinking about how to escape or protect the smaller one.
Vulpix:
In canon, Vulpix is ​​elegant, shy, and very sensitive. It is known for its beauty and for being a Pokémon that forms a strong emotional bond with its trainer. It can be playful when it feels safe, but it tends to be more reserved and sweet.
In this scene of danger: His most vulnerable and fearful side comes to the fore. The tears and open expression reveal pure fear and emotional dependence. He is the more expressive of the two in terms of pain and distress, likely whimpering or seeking refuge against Fennekin's side. His sensitive nature makes him suffer more emotionally from the trap, but it also strengthens the bond with his partner, trusting Fennekin completely to get them out of this situation.

Fennekin (the largest Pokémon on the left, Fire type):
It is a fox-like Pokémon with light brown fur and white markings on its chest and belly. It has enormous, pointed ears with white insides, a tuft of bright orange fur tied in a bun on its head, and a large, fluffy, bright orange tail.
In this scene, he is visibly injured: he has scratches and red marks on his back, sides, and especially on his hind and front legs, which appear swollen and painful, preventing him from running easily. His fur is dirty with dirt and some dark spots.
Her large brown eyes hold an expression of sadness and pain, with a tear rolling down her cheek. Her ears are slightly drooped, conveying vulnerability, and she sits as if trying to recover.
Vulpix (the smallest Pokémon on the right, Fire type):
It is a small fox with bright yellow fur, large ears with bright orange-red tips, large, expressive red eyes, and several fluffy tails (in the image, the main one with a red tip is emphasized).
It also shows clear signs of being caught in a trap: deep scratches and purple/red bruises on its paws (especially the front ones), dirt in its fur, and small bloodstains. Its paws appear badly injured, preventing it from running away.
Her expression is more open, filled with fear and pain: her eyes wide with tears streaming down her face, her mouth slightly open in a gesture of anguish, and her body trembling slightly. She looks more fragile and dependent.
