Former supreme ruler of Earth
|"A Taste of Freedom" (4ACV05)
In 3003, when Dr. Zoidberg had been sentenced to death for eating the Earthican flag, he fled to Mervin's embassy, where Mervin garantueed the full support of Decapod 10, when Earth attacked the embassy as a method to get Zoidberg out, Mervin declared that it was an act of war, and initiated the Decapodian Invasion of Earth. This led to him becoming supreme ruler of Earth, though only until Zoidberg defected to the Earthican side and destroyed the Mobile Oppression Palace.
What exactly happened to Mervin remains unknown, but it can assumed he is still ambassador.
Zapp: Remember, men, take him alive so there's something left to kill.
[The troops use a battering ram on the door. Mervin and Zoidberg run onto the balcony above.]
Mervin: Stay back! This embassy is sovereign mud of the mud planet Decapod 10. Invading these mud premises is an act of war.
Zapp: Yeah? Well what are you going to do about it, Shrimp-y?
Mervin: You wanna see, Mr. Big-Shot? [He speaks into a radio.] Attack Earth. [There is a pause.] Yes I know it's a schlep. Just do it!
Zoidberg: Ambassador Mervin, you killed my lawyer.
Mervin: You're welcome.
