Current Powers

 * High Hazard Level Physiology: Sento underwent an experiment from Faust which injected him with a certain amount of Nebula Gas. However, instead of mutating into a Smash, the gas retained his body without side affects apart from memory loss (mostly inflicted by Blood Stalk). As result, his initial Hazard Level starts at Level 3, which allows subjects like him to utilize the Build Driver to transform into Kamen Rider Build. Later, his Hazard level rose to 3.7 due to his anger during the battle against Blood Stalk. After continuous usage of the RabbitTank Sparkling Fullbottle, his Hazard level rose to 3.9; and after continuous use of the Hazard Trigger, his hazard level was at 4.4 according to Blood Stalk, last time it was measured. By using a panel from the Pandora Box in the Build Driver, Sento was able to raise his Hazard Level to 6, a feat that should not be possible for a human being. Soon after he raised it to 6.3+ by cranking the Build Driver's Vortex Lever. During his fight with the CD Lost Smash and Shinobu Katsuragi as another Build, Sento raised his Hazard level to 7.
 * Genius-Level Intellect: Sento's most defining trait is his intelligence. He has an advanced knowledge of physics, and developed several of Build's accessories on his own. Since regaining his memories of Takumi Katsuragi, his intellect has combined with the latter as well.
 * Genius Physicist: Sento has an advanced knowledge of physics, having finished a difficult physics test with perfect results. This proves a significant asset in battle, which Sento incorporates into his fighting technique. Sento also seems to understand the fundamentals of time travel as well, as he is currently the only legacy Rider in Zi-O to remember Sougo giving him the blank Ridewatch and return it, knowing Sougo is a time traveler.
 * Genius Engineer: Sento has built the majority of Build's accessories, as well as all of Cross-Z's equipment, on his own.
 * Strategist: Sento has shown himself to be a capable strategist, being able to outwit Blood Stalk on two occasions as well as Namba.
 * English Language Proficiency: Sento is able to read Shinobu Katsuragi's entire file and perfectly translate it back to Japanese verbally.
 * Fullbottle Augmentation: By shaking a Fullbottle in his hand, regardless of whether he is transformed or not, Sento can gain abilities based on said Fullbottle's traits:
 * Rabbit: Allows Sento to gain fast reflexes. First used to defeat Ryuga Banjo in a one-on-one fight.
 * Gold Rabbit: Allows Sento to perform powerful punches. First used to defeat Shinobu Katsuragi's version of Build.
 * Gorilla: Allows Sento to perform fiery punches. First used to fight Ryuga Banjo.
 * Fourth Wall Interaction: Used only for comical purposes, Sento is capable of interacting with Ryuga's recollection of his birth in various ways. This normally involves said recollection being thrown away or knocked off-screen somehow.
 * Hazard Level Measurement: Sento gained this ability following his acquisition of Genius Form. He was able to detect Evolto's rising Hazard Level while fighting him.

Weaknesses

 * Dragon Fullbottle: As seen in episode 10, Sento's body cannot handle the Dragon Fullbottle's power as he transforms into Build KeyDragon, which causes him to be electrified by the energy surges and experiences intense pain. Further use of the Dragon Bottle causes his body to be engulfed in flame-like energy which hurts him even more and forcibly knocks Sento out of his transformation. This was due to Ryuga's Hazard Level 3 synchronizing more effectively with the Dragon Full Bottle from prolonged use and exposure to its energy, while Sento had never used it before, and hence lacked that immunity.
 * Dragon Jelly: Sento is also incapable of using this item as well when he uses Banjou's Sclash Driver.
 * Form Data: As seen on Utsumi's tablet, Namba has data on most of Build's Best Match forms, including tactical data for countering the. They also have data and counters for RabbitRabbit Form, which they used against Sento in the fight with Rogue. Hypothetically, any of Sento's forms can be countered, provided they're analyzed and the opponent is powerful enough to utilize the counters.
 * Hazard Trigger: If Sento uses the Hazard Trigger for too long, it will overstimulate his nervous system and send him into a mindless rampage, destroying anything and anyone in his path until his transformation is cancelled. Raising Sento's Hazard Level appears to prolong the amount of time he can use the Trigger with his consciousness intact. Sento can overcome the effects of the Hazard Trigger by using it along with the FullFull RabbitTank Bottle. When the Force Ride Meter on the Trigger is struck forcefully with an attack, it will paralyze him for a period of time. This weakness is carried over from the Evol-Trigger, which the Hazard Trigger is based on.
 * Hazard Kill Switch (Formerly): With Utsumi's help, Sento designed a switch that would allow the user to overload the Hazard Trigger should Sento ever lose control while using it. Activating the switch would destroy the Hazard Trigger, killing Sento in the process. However, after creating the FullFull RabbitTank Bottle, it was no longer needed.
 * Negative Emotions: Since Sento's acquisition of Genius Form, the form is entirely based around Sento's heroic traits and will not activate should he lose those traits. The first instance of this happening was when the bottle was first completed and Takumi attempted to use it, and could not since he did not have any trust whatsoever in anyone. The second instance was shortly after Evolto had killed Shinobu Katsuragi, causing Sento to enter a fit of rage that prevented the Genius Bottle from activating.
