Background: Brock Edward Lesnar was born on July 12, 1977 in Webster, South Dakota, the son of Stephanie and Richard Lesnar, and grew up on his parents' dairy farm in Webster. He is of German descent. He has two older brothers, Troy and Chad, and a younger sister, Brandi. At age 17, Lesnar joined the Army National Guard, where he was assigned to an office job after his red-green colorblindness was deemed hazardous to his desire to work with explosives.
Context: Lesnar's next defense was against undefeated top contender Cain Velasquez on October 23 at the Honda Center in Anaheim, California at UFC 121. Dana White announced via SportsNation that the UFC would bring back UFC Primetime to hype the fight. Lesnar was defeated by Velasquez for the title by TKO in the first round. On January 11, 2011, Lesnar was announced as a coach of The Ultimate Fighter Season 13, opposite Junior dos Santos, with the two expected to fight on June 11 at UFC 131, but he was struck with another bout of diverticulitis and had to withdraw from the fight on May 12. He was replaced by Shane Carwin, who ended up losing against dos Santos. Lesnar underwent surgery on May 27 to help battle his problems with diverticulitis. Dana White said that he had a 12-inch piece of his colon removed. In its May 2011 issue, ESPN's magazine published a story listing the highest paid athlete based on base salary and earnings for the most recent calendar year or most recent season in 30 sports. Lesnar topped the list for MMA at $5.3 million, which included his reported bout salaries and estimated pay-per-view bonuses. In the summer of 2011, Lesnar announced that he was returning to action, stating, "I feel like a new man. Healthy. Strong. I feel like I used to feel". His return match was scheduled to be at UFC 141 on December 30 in Las Vegas against former Strikeforce heavyweight champion Alistair Overeem. Overeem won the fight by way of technical knockout in the first round. The result of the fight remains controversial, as Overeem tested positive for elevated levels of testosterone prior to his next fight. Lesnar then announced his retirement from MMA, mentioning his struggles with diverticulitis and saying "tonight was the last time you'll see me in the octagon". Speculation about a return to MMA lasted until March 24, 2015, when Lesnar announced in an interview on SportsCenter that he had re-signed with WWE and officially closed the door on a return to MMA, even though he was offered a deal "ten times more" than what he had made previously in his MMA career. He further elaborated that, while he was training for months for a return to the UFC, he felt "physically great but something was lacking mentally". Lesnar added that "[he's] an older caveman now, so [he] makes smarter caveman decisions" and that he chose to sign with WWE instead of returning to MMA because he could "work part-time with full-time pay".
Question: What name did he go by when fighting for the WWE?
Answer:

Background: Sir Joseph Rotblat (4 November 1908 - 31 August 2005) was a Polish physicist, a self-described "Pole with a British passport". Rotblat worked on Tube Alloys and the Manhattan Project during World War II, but left the Los Alamos Laboratory after the war with Germany ended. His work on nuclear fallout was a major contribution toward the ratification of the 1963 Partial Nuclear Test Ban Treaty. A signatory of the 1955 Russell-Einstein Manifesto, he was secretary-general of the Pugwash Conferences on Science and World Affairs from their founding until 1973, and shared, with the Pugwash Conferences, the 1995 Nobel Peace Prize "for efforts to diminish the part played by nuclear arms in international affairs and, in the longer run, to eliminate such arms."
Context: While still in Poland, Rotblat had realised that nuclear fission might possibly be used to produce an atomic bomb. He first thought that he should "put the whole thing out of my mind", but he continued because he thought the only way to prevent Nazi Germany from using a nuclear bomb was if Britain had one to act as a deterrent. He worked with Chadwick on Tube Alloys, the British atomic bomb project. In February 1944, Rotblat joined the Los Alamos Laboratory as part of Chadwick's British Mission to the Manhattan Project. The usual condition for people to work on the Manhattan Project was that they had to become US citizens or British subjects. Rotblat declined, and the condition was waived. At Los Alamos, he was befriended by Stan Ulam, a fellow Polish-Jewish scientist, with whom he was able to converse in Polish. Rotblat worked in Egon Bretscher's group, investigating whether high-energy gamma rays produced by nuclear fission would interfere with the nuclear chain reaction process, and then with Robert R. Wilson's cyclotron group. Rotblat continued to have strong reservations about the use of science to develop such a devastating weapon. In 1985 he related that at a private dinner at the Chadwicks' house at Los Alamos in March 1944, he was shocked to hear the director of the Manhattan Project, Major General Leslie R. Groves, Jr., say words to the effect that the real purpose in making the bomb was to subdue the Soviets. Historians, notably Barton Bernstein, have cast doubt on this story. By the end of 1944 it was also apparent that Germany had abandoned the development of its own bomb and Rotblat asked to leave the project. Chadwick was then shown a security dossier in which Rotblat was accused of being a Soviet spy and that, having learned to fly at Los Alamos, he was suspected of wanting to join the Royal Air Force so that he could fly to Poland and defect to the Soviet Union. In addition, he was accused of visiting someone in Santa Fe and leaving them a blank cheque to finance the formation of a communist cell. Rotblat was able to show that much of the information within the dossier had been fabricated. In addition, FBI records show that in 1950, Rotblat's friend in Santa Fe was tracked down in California, and she flatly denied the story; the cheque had never been cashed and had been left to pay for items not available in the UK during the war. In 1985, Rotblat recounted how a box containing "all my documents" went missing on a train ride from Washington D.C. to New York as he was leaving the country, but the presence of large numbers of Rotblat's personal papers from Los Alamos now archived at the Churchill Archives Centre "is totally at odds with Rotblat's account of events". Due to suspicions that he was a Soviet spy, Rotblat was not permitted to re-enter the United States until 1964.
Question: What did he do after he left?
Answer:
Rotblat was accused of being a Soviet spy
