The light novel 'Re:Zero - Starting Life in Another World' also fits this. Subaru is a normal boy who is suddenly thrown into a fantasy world. At first, he is completely out of his depth, but through countless deaths and resurrections, he learns, grows, and slowly becomes a hero - like figure who can save others. His journey from being a zero in this new world to a hero is full of hardships and character development.
A famous one is that of Narendra Modi. He came from a simple family background. Through his hard work in the political arena, rising from the grassroots level in the Bharatiya Janata Party, he became the Prime Minister of India and has been making significant changes at the national and international levels.
Mangalyaan, India's Mars Orbiter Mission, is also a zero to hero story. India had limited resources compared to other space - faring nations. But the Indian Space Research Organisation (ISRO) with its dedicated scientists worked tirelessly. They overcame numerous challenges and managed to send a spacecraft to Mars on a relatively low budget, making India the first Asian nation to reach Mars orbit, which was a remarkable achievement.
Sashi is also a main character. She is Penn's friend and often helps him during his adventures. She is very smart and resourceful, coming up with great ideas to solve problems.
In the light novel 'Konosuba: God's Blessing on this Wonderful World!', Kazuma starts as a NEET (Not in Education, Employment or Training) in his world. But when he is transported to a fantasy world, he has to learn to survive and thrive. Along with his strange group of companions, he gradually becomes a hero in his own way. He may not be the typical noble hero, but he overcomes many challenges and grows from his initial state of being a 'zero'.
One interesting story could be about Penn's first big mission. He might be nervous but quickly rises to the occasion, using his wits and the help of his friends to save the day in a wacky, alternate - world setting.
One idea could be a story where Shashi gets a special power upgrade that she has to learn to control while on a mission. Maybe she accidentally freezes time instead of just slowing it down like she usually does.
Try looking in libraries. They might have books or anthologies of horror stories that could feature tales about hero zero. Another option is to follow specific authors or storytellers on social media who specialize in this genre; they might post or recommend such stories.
I'm not sure specifically as I haven't read it. But generally, a web novel with 'otherworldly hero business' might be about a hero's adventures in a different world, perhaps involving battles, quests, and character development.
