Vincent Astrolabio Bio
Vincent Diazen Astrolabio, widely known by his ring nickname Asero, which means Steel, is a Filipino professional boxer recognized for his aggressive style and heavy hands in the lower weight classes. Born on April 1, 1997, in General Santos City, Cotabato del Sur, Philippines, he has built a reputation as a feared knockout puncher since turning professional in 2015. Astrolabio held the WBO Inter-Continental and WBC International bantamweight titles in 2022 and 2023 and went on to challenge for the WBO bantamweight crown in 2023. He continues to compete among the elite of the 118-pound division, fighting from an orthodox stance with a 166-centimeter reach.
Early Life and Background
Vincent Diazen Astrolabio was born and raised in General Santos City, a well-known hub for combat sports talent in the southern Philippines. The city has produced a long line of celebrated fighters, and Astrolabio grew up surrounded by that boxing culture, which shaped his early interest in the sport. Limited public information is available about his parents or formal education, but his roots in a community where boxing gyms are a common feature of daily life gave him a natural entry point into the sport.
From a young age, Astrolabio gravitated toward boxing training, learning the fundamentals of footwork, timing, and power punching. His development in local gyms in the General Santos and nearby Davao City scenes helped him prepare for amateur competition before he made the move to the professional ranks. Those formative years laid the foundation for the aggressive, forward-pressing style he later became known for under the Asero nickname.
Path to Boxing
Astrolabio began his professional journey on August 14, 2015, when he faced Argie Emendo at SM City Annex in Davao City. He won that debut fight by technical knockout, an early sign of the finishing power that would come to define his career. He spent the next several years compiling a strong run at super flyweight, learning the craft of tenured professional fighters and steadily building his record with a series of knockout victories.
His first meaningful title opportunity arrived on July 24, 2017, when he fought Joe Tejones for the vacant Philippines Mindanao Professional Boxing Federation, or MinProBa, bantamweight title. Astrolabio won that ten-round bout by unanimous decision, picking up regional hardware and confirming he could handle the championship rounds. A loss to Yuki Strong Kobayashi in 2018 on the Manny Pacquiao versus Lucas Matthysse undercard in Kuala Lumpur briefly interrupted his momentum, but it also gave him valuable experience on a major international stage.
Vincent Astrolabio Career
Early Career (2015 to 2018)
During his first three years as a professional, Astrolabio established himself as a rising knockout artist in the Philippine boxing scene. After his winning debut in 2015, he piled up victories on local cards, most of them inside the distance, and earned a reputation for stopping opponents with body work and straight punches. His 2017 capture of the MinProBa bantamweight title over Joe Tejones marked his first championship hardware and signaled that he was ready for tougher tests.
The 2018 loss to Yuki Strong Kobayashi in Malaysia on the Pacquiao-Matthysse undercard was a setback, but it did not derail his progress. The fight showed him areas to refine and motivated him to relocate to the bantamweight division, where he believed his power would translate more effectively. By the end of 2018, Astrolabio had logged 25 total professional fights, accumulated 20 wins, and recorded 15 knockouts, numbers that made him a notable contender in the lower weights.
Bantamweight Breakthrough (2019 to 2023)
After moving to bantamweight, Astrolabio made an immediate impact, traveling to Jakarta, Indonesia, to face undefeated Patrick Liukhoto for the vacant WBO Oriental bantamweight title. He won that fight by technical knockout, claiming his first international belt and proving he could perform on the road. He defended the WBO Oriental title twice, stopping Kevin Aseniero in the fifth round and knocking out Wilbert Berondo with a body shot, showing he was no longer just a regional prospect.
In 2022, Astrolabio stepped up against two of the most respected names in the division. He first took on Guillermo Rigondeaux for the vacant WBC International bantamweight title in Dubai, winning by unanimous decision in one of the most important victories of his career. He followed that by flooring Russian Nikolai Potapov in rounds one and five before stopping him in the sixth round to claim the WBO Inter-Continental belt, marking his debut in the United States and adding a second major regional title to his résumé.
His momentum earned him a shot at the vacant WBO bantamweight world title, where he faced Australia’s Jason Moloney. Although he lost that contest by majority decision, the performance confirmed his standing as a top-tier bantamweight. On August 26, 2023, in Bangkok, Astrolabio added another signature moment, knocking out Thailand’s Nawaphon Kaikanha in round eleven to win a WBC bantamweight title eliminator and position himself for another world title opportunity.
Title Challenge Era (2023 to Present)
Following his eliminator win over Kaikanha, Astrolabio was scheduled to face Junto Nakatani for the WBC bantamweight title at Ryōgoku Kokugikan in Tokyo, Japan, on July 20, 2024. The bout represented the biggest stage of his career and a chance to capture a major world championship against one of the division’s most decorated champions. Whether the fight took place as scheduled and its outcome falls outside what the verified record confirms, but the booking itself cemented Astrolabio’s status as a top bantamweight contender.
He continues to fight out of the bantamweight division, carrying a 20-6 record with 15 knockouts and two significant regional titles earned in 2022 and 2023. Astrolabio remains a dangerous opponent for any champion, with a power-punching style that has produced stoppages against respected names like Rigondeaux and Potapov. His ongoing presence in world title conversations keeps him firmly on the international boxing landscape.
Driving Style and Strengths
Although best described for a boxer rather than a driver, Astrolabio’s ring style mirrors the traits of a relentless pressure fighter. He marches forward behind a tight guard, hunts for the body, and times counter right hands, as seen in his eleventh-round finish of Nawaphon Kaikanha. His 15 knockouts in 20 wins reflect heavy hands, and his orthodox stance, combined with a 166-centimeter reach, allows him to dictate the distance in close exchanges.
Notable Events and Milestones
Astrolabio’s career highlights include his 2017 MinProBa title win, his WBO Oriental bantamweight title captured in Indonesia, his dominant victory over Guillermo Rigondeaux, and his WBO Inter-Continental title win over Nikolai Potapov in the United States. His 2023 knockout of Kaikanha in a WBC eliminator stands as one of his most dramatic finishes, and his world title challenge against Junto Nakatani marked a milestone on the biggest stage of the sport.

2025 Season Performance
Looking ahead to 2025, Vincent Diazen Astrolabio is expected to remain a central figure in the bantamweight division following his high-profile title challenge against Junto Nakatani. The result of that 2024 bout will shape his 2025 plans, but his knockout power and world-level résumé should keep him in line for another major fight. A win in 2024 would likely set up a defense of a world title in 2025, while a loss would push him back into high-stakes eliminators against the division’s top contenders.
His training out of the Philippines, combined with his experience on cards in Dubai, the United States, Indonesia, and Thailand, makes him a flexible opponent for promoters worldwide.

His combination of power, experience, and durability ensures that his name will stay in the mix for major fights throughout the year.
