Diphine

Dr. Diphine Alchemy is a ricebodied birdectalyte from Gravildus, a historian, and a former crime scene investigator at the Bugtown Police Department, specializing in superpowered criminals. As a result of B's creating and trying to undo InstAntpoint, Diphine was assigned as his senior lab tech. During an expedition on Syuska, Diphine found the Time Rock. Once he found the rock, he woke up in his hotel room and learned his expedition team had been found dead. He then ran off to Bugtown and Earth while unknowingly becoming Tithonus under Arunasura's control. As "Tithonus", Diphine was possessed to restore the abilities of several criminals from the InstAntpoint timeline. After being freed from Arunasura's control, he joined Team InstAnt, using his scientific expertise to aid in protecting Bugtown. He also grows close to Natalie Lee, eventually him trying to find a way to suppress her powers, and later to potentially cure her of her Killer Silo side. Their relationship becomes strained as Diphine finds out that Natalie recklessly tried to use a piece of the Time Rock in order to attempt to get rid of her powers, but when she suffers a life-threatening injury, he's quick to do all he can to save her.

Sometime after May 2018, when B sacrificed himself to Fast Time, Diphine left Bugtown and relocated to his home on Gravildus to make amends with his parents after they had blamed him for his sister's death years prior.

Diphine, along with the rest of the multiverse, was vaporized by a wave of antimatter during The Great EvilBob Disaster. It's presumed he was resurrected after Earth-Gravildus-Batorok was created.
