Well, without more context, it's hard to say precisely. But generally, if it's a story about a general's secret armory, it could involve a plot where the existence of this armory is in danger of being exposed. Maybe there are bad guys trying to steal from it or use the weapons for evil purposes. And General Knoxx has to protect it at all costs. There could also be elements of mystery, like how the armory was built, what's inside it that's so special, and who else knows about it.
Since I don't know the specific story, General Knoxx is likely one of the main characters. There might also be his allies or soldiers who help him guard the secret armory.
The Pokémon special, Ruby, was a fictional story created by Japanese manga artist Hiroko Hanami in 1997. The story was about an elf named Ruby who was learning Pokémon knowledge and skills in a mysterious Pokémon training class. Ruby gradually became a powerful Pokémon Master and worked with his Pokémon companions to protect the world from the threat of evil forces.
Well, her sister Yang would definitely be one of the main characters. Yang would be very protective of Ruby and would try to help her in any way she could. Weiss would also be important. She might use her intelligence and Dust - related skills to assist Ruby. And Blake, with her stealth and combat skills, could be crucial in protecting Ruby and guiding her through difficult situations.
I don't know exactly who Ruby is without reading the story. But she is likely the main character, a person who has some kind of story related to reading in the street during her own time.
The relationship between Max and Ruby makes it special. Ruby's caring yet sometimes bossy nature towards Max creates an interesting dynamic. It's a story that many siblings can relate to.
