Carolina Panthers. "Thunder III", a gelding registered as Me N Myshadow, was the understudy to Thunder II, and trained specifically for mascot duties beginning at age three when he was started under saddle. He began performing at preseason games in 2013. Although Thunder II was still active as team mascot during the 2013–14 season, Thunder III was sent to Super Bowl XLVIII because he was younger and better able to handle air travel. He is described as laid-back, preferring to doze off during games when not performing. History The original "Thunder", JB Kobask, was loaned to the Denver Broncos by Sharon Magness-Blake of Magness Arabians after she received a phone call from team officials asking if she had a "white" horse. Thunder's debut as team mascot was on September 12, 1993, during the Broncos' victory over the San Diego Chargers. Angela Moore, his rider at the time, galloped him down the field after each Broncos touchdown. Thunder's mascot duties were expanded to include delivering the game ball to the referees at the start of each home game. Spectators were allowed to interact with Thunder and pet him prior to the game. Magness said, "Thunder is friendly, and Broncos fans think it's good luck for the opposing team to pet our mascot". He was particularly popular with children, appeared on T-shirts, and was referred to as the "second most popular Bronco" after former quarterback John Elway. Thunder appeared at Elway's 1999 retirement gala. When team uniforms were redesigned in 1997, Thunder was the inspiration to incorporate a horse-head profile as part of the logo on the team's helmets. During a February 4, 1997 press conference introducing the new logo, the team president and the art director for Nike, creators of the new design, described it as "a powerful horse with a fiery eye and mane." The original Thunder, also known as Thunder Sr., was retired in 2004 after serving 11 years as the team mascot. Magness-Blake replaced him with Thunder II, a 1994 Arabian gelding registered as Winter Solstyce. He was Magness-Blake's personal pleasure riding horse prior to taking on his new role as team mascot. As Thunder II grew older, Magness-Blake anticipated the need for a replacement and added a third gray horse to the team. He became known as Thunder III, a 2000 Arabian gelding registered as Me N Myshadow. Thunder III initially served as the understudy for Thunder
