Problem: Background: Yen was born in Guangzhou, China. His mother, Bow-sim Mark, is a Fu Style Wudangquan (internal martial arts) and Tai Chi grandmaster, while his father, Klyster Yen (Zhen Yun Long ), is a newspaper editor. When he was two years old, his family moved to Hong Kong and then to Boston when he was 11. His younger sister, Chris Yen, is also a martial artist and actress, and appeared in the 2007 film Adventures of Johnny Tao: Rock Around the Dragon.
Context: Yen describes himself as a mixed martial artist. He learned Tai Chi from a young age under his mother's tutelage. He then wanted to learn Taekwondo in his teenage years, earning a 6th Dan in the process. At the time, the Beijing Wushu Team had a scout in the United States and invited Yen over to Beijing, China, where he began training at the Beijing Sports Institute, the same facility where champion-turned-actor Jet Li trained; this is where the two of them crossed paths for the first time. Upon his return to the United States, Yen won gold medals in various wushu competitions. Yen later went on to discover and seek knowledge on other martial arts styles; he would later obtain black and purple belts from judo and Brazilian Jiu-Jitsu, respectively, and went on to study the art of Parkour, Wrestling, Muay Thai, Kickboxing and Boxing under various trainers. His exposure to mixed martial arts (MMA) was heightened when he went back to the United States from 2000 to 2003. While making his Hollywood debut, he also took time off to learn the various martial arts forms. Yen's progress was evident when he returned to Asia, where he implemented his newfound knowledge of MMA, showcased in films such as SPL: Sha Po Lang (2005), Flash Point (2007), and Special ID (2013). Near the end of 2007, Yen added a new martial arts system to his arsenal. He was offered the role of Wing Chun grandmaster and mentor of film star Bruce Lee, Ip Man, in a 2008 film named after the grandmaster. He worked hard and studied Wing Chun under Ip Man's eldest son, Ip Chun, for 9 months before tackling the role. Ip Chun has since praised Yen for his effort, his skills as a martial artist, and his ability to grasp the full concept of Wing Chun much faster than anyone else he has taught. Yen believes that combining many martial arts together will produce the most effective and harmonious style. Yen has said, "When you watch my films, you're feeling my heart." He believes in practical combat, and in his opinion, MMA is the most authentic type of practical combat. He has mentioned that he would have competed in the Ultimate Fighting Championship if he did not have a recurring shoulder injury.

Problem: Background: Comet is the name of two fictional comic book characters owned by DC Comics whose adventures have been published by that same company. The first character was a sapient horse with magical powers who was once a centaur in ancient Greece. The second character is a shapeshifter with three forms (male, female, and winged centaur). Both characters are connected to the Superman family of titles.
Context: Comet the Super-Horse is a fictional character that appears in comic books published by DC Comics. Comet was introduced in the Superboy story in Adventure Comics #293 in February 1962, then appeared regularly with Supergirl beginning in Action Comics #292 in September 1962. Comet was one of a series of super-powered animals, including Streaky the Supercat and Beppo the Supermonkey, that were popular in DC's comics of the 1960s. Comet was Supergirl's pet horse and, while in his human form as Bill Starr, her brief boyfriend. Comet also had a brief romance with Lois Lane in her comic book. As he described to her telepathically, he was originally a centaur in ancient Greece named Biron. The witch Circe gave him a potion to turn him fully human after he prevented an evil sorcerer poisoning her water, but by mistake made him fully horse instead due to the Sorcerer. Unable to reverse the spell, she instead gave him superpowers, including immortality. The Sorcerer asked his teacher to help him against Biron and they were able to imprison him on an asteroid in the constellation of Sagittarius, which he had been born under. However, when Supergirl's rocket passed, it broke the force field, enabling him to escape. Later, after meeting Supergirl, he went on a mission with her to the planet Zerox, where a magic spell was cast that turned him into a human, but only while a comet passes through the solar system he is in. As a human, he adopted the identity of "Bronco" Bill Starr, a rodeo trick-rider, whom Supergirl fell in love with. Comet made sporadic appearances in comic stories through the 1960s, and even became a member of the Legion of Super-Pets, a group consisting of the aforementioned super-powered animals. A traditional equine Comet is partially seen in Legion of Three Worlds #1. He is part of a display in the museum Superboy-Prime visits. The museum does have displays of the supermen of the multiverse and the Kristen Wells Superwoman so it is unclear whether this means Comet has returned to regular continuity.
