Kevin Uxbridge Kevin Uxbridge was the assumed Human identity of a Douwd who came to Earth in the late 23rd century . " Kevin " was born in 2281 . While disguised as a Human student aboard a ship at sea , he met a woman named Rishon . Although her parents did not approve of him , within two hour s of their meeting Rishon asked " Kevin " to marry her . Kevin fell in love with Rishon , decided to put aside his powers and live as a Human . Rishon and Kevin were married in 2313 , and spent most of their lives in the aquatic city New Martim Vaz , in Earth ' s Atlantic Ocean . He became a botanist , specializing in symbiotic plant life . He never told Rishon about his true identity . In 2361 , the couple moved to the Federation Delta Rana IV colony , " hoping it would make [ them ] fall in love all over again " . Their life on Rana was full and satisfying , but in 2366 , the colony was attacked and destroyed by the Husnock . The moral code of the Douwd prevented Kevin from taking deadly action , even in defense of the woman he loved , so tried to fool them with his powers , though unsuccessfully . Rishon , however , attempted to defend the colonists and died along with them . Racked with grief , Kevin annihilated the entire Husnock species ( estimated at fifty billion beings ) . Subsequently , Kevin recreated his home and wife . When an away team led by Commander Riker arrived to investigate the colony ' s destruction and the apparent survival of the Uxbridges and their home , Kevin attempted to protect his home , first with a buried snare and then by threatening the away team with a non - functioning weapon . Lieutenant Worf considered this an act of unmitigated gall , something he admired . Riker encouraged the Uxbridges to return to the with him , but they refused . While the away team was investigating on the surface , Counselor Troi attempted to probe the Uxbridges ' minds . To hide his true identity , Kevin placed the tune from a music box of Rishon ' s into Troi ' s mind . This tune distracted her , eventually causing her considerable suffering . Hoping to lure the " Enterprise " - D away from Rana , Kevin created a false warship , which appeared from the Lagrange point of Rana ' s farthest moon and fired on the " Enterprise " - D with proton - antiproton energy equivalent to forty megawatt s . The crew of the " Enterprise " naturally assumed this vessel was the same Husnock warship that had attacked the colony , though the design was unknown to the Federation . When the " Enterprise " - D returned fire , the warship quickly left orbit . As the " Enterprise " - D attempted to catch up with it , the ship matched " Enterprise " - D ' s acceleration exactly , and the " Enterprise " - D was unable to catch it . The " Enterprise " - D returned to the Delta Rana system , and Captain Picard encouraged the Uxbridges to leave the planet ; they again refused . After Picard had returned to the ship , Kevin brought the warship back in a slightly different configuration , and fired on the " Enterprise " - D with 400 gigawatt s of particle energy , injuring 66 crew members . The " Enterprise " returned fire , but none of its weapons were effective , and it was forced to leave orbit . Picard hypothesized that the ship was protecting Kevin and Rishon , and to test his theory he informed Kevin that the " Enterprise " - D would not leave Rana IV as long as Kevin and Rishon were alive . In response , Kevin brought the warship back and had it fire upon the planet , appearing to destroy his home . Picard then ordered a single photon torpedo launched against the warship , and Kevin caused the previously impenetrable ship to be utterly destroyed so that the " Enterprise " would have no reason to remain in the Rana system . Three hour s later the Uxbridge home , and the Uxbridges , were back . Picard had them beam ed directly to the bridge of the " Enterprise " - D , where he explained that he had deduced that Rishon had in fact died in the attack , and Kevin had somehow recreated her and their home . Exposed , Kevin uncreated the copy of Rishon , and disappeared from the bridge . He went to the bedside of the suffering Counselor Troi and removed the music from her mind . When Picard demanded the truth of him , Kevin revealed his true nature and that , in an instant of his regretful grief , he had utterly annihilated the entire Husnock race with a single vengeful thought . Picard decided that humanity was not qualified to judge Kevin ' s crime , and permitted him to return to the planet and create his wife and home once more . Colony records indicated that Kevin was 85 years old at the time of the attack , although this was of course based on his false Human identity . In reality , he had lived in the Milky Way Galaxy for many thousands of years . ( )
