#xensen

The most important aspect of Xeno's character is who he was before, who he was when he first met Senku. Xeno wasn't born a bad person, he became one over time, as he grew up he felt like his dreams were taken from him. He always had some authoritarian tendencies, but those tendencies were brought forth the more he became shackled by authority.

His true passion is science, all of his wants are motivated by his selfish drive to do as much science as possible, no matter the financial and ethical barriers.

Xeno first met Senku when he was 10, Xeno being 20-21. They were online friends for 9 years, so they both got to see each other grow up.

Senku's drive to save humanity was instilled in him because he rejected Xeno's crumbling ethics. His trip to Africa, his studying biology and topics far beyond rocket science, was because he knew people like Xeno posed a threat to humanity. He knew he would have to counter mad scientists from a very young age.

Xeno and Senku are meant to be mirrors of each other, this shows in Xeno's design. I will say I am very proud because I figured this out years ago before Boichi (the manga artist of Dr. Stone) confirmed it several days ago.

Both Xeno and Senku represent the quest for knowledge by oneself because they feel like nobody will be as passionate while carrying the torch. Xeno decided to become a dictator because he felt like he could be the only one willing to sacrifice morality for the sake of human scientific progress, while Senku felt like he could be the only one willing to do everything possible to save every human on Earth.

(Notice the difference in their eyes, Xeno's don't shine. This becomes more important symbolically later. This theme is brought up again and again.)

In summary, Xeno is a passionate person who lost all hope in humanity because of the barriers that were placed in front of him. He is arrogant, controlling, and has sinister motivations.

Senku is the scientist of light, while Xeno is the scientist of the dark. Senku is selfless, Xeno is selfish. Senku studied science in the hopes of progressing science at the benefit of everyone, while Xeno studied science in the hopes of progressing science at the benefit of himself - his curiosity.

As I've grown up alongside Dr. Stone, I've noticed the shift in my own character. I love Dr. Stone because it is all about wanting to learn as much as possible. I find that very relatable. Like Senku, I loved reading books on quantum theory and chemical biology when I was little - although I was like Taiju, I rarely understood it. But I continued to read regardless because I just wanted to know everything, I was and am endlessly curious.

I found myself relating to Senku after I first caught up to Dr. Stone in January 2020, but over time I have begun to understand Xeno further - most people are not curious. They feel no passion for learning more and the importance of building upon existing human knowledge, even if it could help many. Sometimes we need great, powerful people, to drive humanity forward even at the cost of one's moral character.
