Using Pikachu's unique electric abilities in the description of its crying can be effective too. For instance, the tears could be described as having a slight electric charge, sparking a bit as they roll down its cheeks. This ties in with Pikachu's nature as an Electric - type Pokémon and makes the crying scene more unique and memorable.
One possible reason could be that Pikachu is separated from Ash. In many fanfictions, their bond is so strong that being apart would be extremely distressing for Pikachu, leading it to cry.
Set the right scene. If it's a rainy day and she's alone in the forest, that gloomy setting can amplify her feelings of sadness and make her crying more believable. Also, the writer can describe how the raindrops mix with her tears, creating a more poignant image.
They can describe his physical reactions. For instance, 'Merlin's shoulders shook as he sobbed, his hands covering his face as hot tears streamed through his fingers.' This gives a vivid picture of his crying.
Writers can describe Ryder's physical reactions. For example, they can write about his eyes welling up with tears, his lip trembling, and his voice cracking. This will give the readers a clear image of him crying.
Describing the setting around him can enhance the mood. If he's crying in a desolate place, it can make the reader feel his loneliness more. Or if he's crying in a crowded room but still seems so alone, it creates a powerful contrast.
One way is to build up to the crying moment. Show the events leading to it and the character's struggle. And when they cry, describe it vividly - the hiccups, the gasps for breath. Make the reader empathize with the character's pain or joy that brings on the tears.
To depict crying in comics, you could focus on the character's expression. Maybe have them scrunch up their face, tremble their lips, and have big, teary eyes. Also, add some droplets or streaks of tears for a more dramatic effect.
Many writers portray their relationship as an unlikely friendship. Given their different natures, it makes for an interesting dynamic. Mewtwo is a product of scientific experimentation, while Pikachu is a natural - born Pokemon. Their relationship is often shown as a way for Mewtwo to discover the simple pleasures of the Pokemon world through Pikachu, and for Pikachu to understand the deeper, more complex emotions that Mewtwo experiences.
Writers often use vivid descriptions of the girls' facial expressions. For example, they might write about Blossom's eyes welling up with big, glistening tears, and her lips trembling. They also describe body language, like Bubbles slumping her shoulders and hugging herself when she's crying. Sound effects can be used too, like the soft sobbing noises the girls make.
One way to develop her character is through her relationships. Besides Ash, she could have a special friendship with other Pokémon in Ash's team. Maybe she is like a big sister to the younger Pokémon, teaching them things and protecting them. This would show her nurturing side and develop her character further.
