Charlie & Beevor eventually went in to interrogate their subjects. They both used the same playbook.

"You are at Space Patrol Delta intergalactic headquarters on Onyx. You are the first Power Rangers we have seen since the war against the Evil Power Rangers. They were all either killed in battle or surrendered and sentenced to prison for their crimes. The surviving powers now belong to SPD any unauthorized Power Rangers are illegal and considered an enemy of Intergalactic Peace Accords. Why did you come to Onyx the sight of the final battle against evil? You clearly were not teleported here, all teleportation to and from this planet is highly restricted to the point you must make a request a year in advance or be in a ship about to explode in orbit. The only ships in the vicinity are registed to SPD. So how did you come to be on this planet? Why were you carrying a corpse? Whoever that once was, in case of any disease you might be trying to spread the body was taken to an incinerator." They both pulled out their Delta Morphers in case they needed to call upon judgement of the highest authority with SPD.
