Dr.Stone’s 151st chapter titled “Z=151: Dr. X” introduced Dr.Xeno as the antagonist for the New America City Arc. After reaching America, Perseus came under heavy from an unknown assailant who was later revealed to work for Dr. Xeno.
He is the first revived Adult the group has ever encountered. To make matters worse he is a scientist on par with Senku himself.
Senku has been able to one-up his opponents with his incomparable intelligence and new gadgets like the phone he used to defeat Tsukasa or the drone he used to petrify Ibara.
Unlike previous arcs, Senku can no longer rely on his inventions to win against his opponent as he is an adult scientist who owns and operates a Haber–Bosch Plant.
The plant allows them to produce unlimited amounts of ammonia and gunpowder. Along with the plant and its by-products, the enemies own an armoury full of different weapons and various other gadgets.
All these factors combined placed the science kingdom at a humongous disadvantage.
It is no longer a battle of brain versus brawns but a battle of wits. Senku isn’t the smartest person in the room anymore, nor is his intelligence a unique trait.
Barely shaken by that fact, he welcomes a challenge. Finally facing a scientist like himself, how will Senku become victorious in this battle of wits?
This goes on to question, Is Tsukasa the strongest opponent he has faced, or is this threat far more dangerous than him? Tsukasa may have relied on physical strength and characteristics to battle Senku, but he always feared his scientific innovation.
If Tsukasa was Senku’s antithesis then Dr. Xeno is his evil twin. This scientific knowledge makes Dr. Xeno a far bigger threat than Tuskasa ever was.
