クロノ・ドラン

Chrono Dran is one of the original Zodiac Time Beasts, specifically the "Time of the Dragon". He is also the younger version of Chronojet Dragon, who arrived at the current timeline from a separate one due to the Gear Chronicle Singularity event, which brought Stride to Planet Cray and Earth. He is able to turn into Chronojet Dragon for a short amount of time.
