Yes, Kill la Kill originated as a manga. It gained popularity and was later adapted into different mediums, with the anime being particularly well-known.
A common villain origin story could be that of a character named Jack. He was once a kind and talented scientist. But after being constantly ridiculed and overlooked in his workplace for his unorthodox ideas, he became bitter. His resentment grew when his life's work was stolen by a more popular colleague. This led him to use his scientific knowledge for evil, creating chaos in the city with his dangerous inventions as a way to get revenge on those who wronged him.
In a villan origin story, the initial situation of the character is crucial. If they start off in a marginalized or oppressed position, like a lower - class citizen in a highly class - divided society, it can lead to feelings of anger and resentment. Another key is the series of events that push them over the edge. It could be a series of rejections, like being rejected by a romantic partner multiple times and then by society as a whole. Also, the lack of positive role models or support systems can contribute. If a character has no one to guide them in the right direction when they face difficulties, they are more likely to turn to villainy.
Sure does! The official manga of Kill la Kill exists and offers a different take on the story compared to the anime. It expands on certain plot points and gives more depth to the characters.
