The comics might focus on their adventures together, exploring new places and facing challenges. Also, there could be character development as they grow and learn from each other.
The 'braixen sex comic' is likely to be in the category of adult or explicit content. It goes against social and ethical standards and should be avoided.
I'm not entirely sure specifically as it could be a very niche or custom - made visual novel. It might be centered around a Braixen, which is a Pokémon. Maybe it tells a story from the perspective of the Braixen or has adventures involving it.
The story of the Lucario x Greninja comic is quite engaging. It combines elements of fantasy and combat, with both characters evolving and growing throughout the plot. There are unexpected twists and turns that keep you on the edge of your seat.
One idea could be a story where the male reader is a trainer who discovers a female Lucario in the wild. They form an instant bond and start a journey together, facing various challenges in battles and in understanding each other's emotions.
Sir Aaron's character might be developed through flashbacks. We could see his past deeds, his kindness towards Pokémon, and how he was misunderstood by some. His relationship with Lucario could be shown as a way to redeem himself in the eyes of the Pokémon world, and this would shape his character further.
A common theme is friendship. The male trainer and Lucario form a strong bond that helps them through various challenges. Another theme could be growth, both for the trainer in terms of becoming a better Pokémon trainer and for Lucario in evolving its skills.
Love and connection are perhaps the most prominent themes. The stories usually explore the unique connection between a human (the reader) and the female Lucario. It can be a platonic love at first, but often evolves into a deeper, more romantic kind of love. There are also themes related to the Lucario's unique abilities and how they are used to protect or help the reader in different situations.
