A Rival Appears!

is the 89th chapter of the Dragon Ball Super manga.
==Summary==
At Capsule Corporation, Trunks tries, with little success, to view the contents of the data disc that was retrieved from Dr. Hedo's safe. After using his mother's computer, he manages to get inside where he sees blueprints for a strange creature briefly before a computer virus takes over. His mother enters alongside Bulla, who promptly fixes the computer, and tells Trunks that he will be heading to school together with Mai who has been enrolled into high school herself to avoid suspicion.
At school, Mai introduces herself to the class followed by another good-looking boy named Baytah. Throughout the day Mai keeps a close eye on Baytah much to Trunks' annoyance who attempts to gain Mai's attention during basketball. After a stunning display of speed is captured by Baytah, secretly an android called Beta 1, his creator Dr. Hedo believes that he may be the one responsible for defeating his Alpha Series and stealing his disc. Unfortunately for the doctor, Alpha 12 does not recognize Trunks, remembering the one that defeated him had blonde hair instead. Nevertheless, Dr. Hedo orders Beta 1 to hunt the culprit down.
During the next class, Mai points out to Trunks that Baytah is really an android and must be looking for someone at the school. Not wanting his identity to be revealed as Saiyaman X-1, Trunks avoids a number of Beta 1's "accidents" that act as attempts to expose him, such as deliberately bending over to "tie his shoes" as Beta 1 throws a football at him, causing the football to reflect and hit a nearby fire extinguisher, soaking Beta 1. After school, Goten nonchalantly lifts a truck with one arm while grabbing a soft ball leading Beta 1 and Dr. Hedo to believe he must be the culprit who defeated the Alpha Series.
Beta 1 reveals a mock superhero costume of his own and attacks Goten without hesitation as he demands that he return the data disc. Trunks hands Mai his school bag as he runs off back into the school to undergo his transformation as Saiyaman X-1 before proceeding to take over the confrontation with Beta 1 from Goten. Despite being a more powerful android, he still proves to be no match for Trunks who tosses him onto the school field out of harm's way of the other students. As a result, Beta 1 presses a button on his belt that causes a Battle Jacket to appear. He proceeds to fire off a missile towards the students behind Trunks, but he is able to catch it and throw it into a nearby lake. 
After Trunks knocks the Battle Jacket down, Mai stumbles and drops her bags with the data disc being revealed to be inside. Dr. Hedo orders Beta 1 to catch the girl and fires off a barrage off missiles to distract Trunks. Thankfully all the missiles are countered by the appearance of Goten now in his Saiyaman X-2 outfit. The top half of the Battle Jacket detaches itself leaving its bottom half, a self-aware android in its own right known as Beta 2 behind. Goten makes quick work of Beta 2 while Trunks shatters the Battle Jacket surrounding Beta 1 before catching Mai who recalls fond memories of Future Trunks from several years ago after seeing her savior up close.
Back at Dr. Hedo's lab, despite yet another loss, the scientist is enamored by the awesome hero costumes of Saiyaman X-1 and X-2 and vows to begin work on his next set of androids who he states will be far stronger and cooler than those that came before.
