It is unknown if this new Ultraman will appear in Ultraman Trigger, or in the third Ultra Galaxy Fight series. Since there's no official romanization yet, his name can also be translated as Ultraman Regulus, with Regulus being the bright star seen in the Leo constellation. Is there a possibility that he might tie-in to Ultraman Leo? That is for us to find out in the future.
