Athletes have been compared to fictional and mythical characters for as long as sports has been a part of pop culture. It might seem unusual, however, to hear UFC featherweight champion Max Holloway explain what he has in common with the little blue fish that suffers from short-term memory loss in “Finding Nemo.” “You can call me Dory,” he said as he prepared for his first title defense, against Jose Aldo, whom he took the belt from in June. “I don’t even remember fighting this guy. It’s a whole new guy, and I’m going down and I’m going to fight him. This is what I have to do.” The rematch headlines UFC 218 on Saturday in Detroit. But Holloway, who has won 11 straight fights, wasn’t supposed to fight Aldo again. He had been booked for a fight against Frankie Edgar, but Edgar suffered a broken bone in his face while training and pulled out of the bout. Aldo was quick to step in on late notice for the opportunity to regain the title. “I think this is a new chapter in my story,” he said. “I think that the first fight was great, and I think that we gave our all. We both came out as champions. I think it was a great fight, and I think that the fans are the ones who win.” Holloway had been ready to move on to a new challenge, but wasn’t about to turn down an opportunity to defend his belt and get a second win over the longest-reigning featherweight champion in UFC history. “I’m just having a fight,” Holloway said. “I told the people of Detroit, I told my fans, I sacrificed too much time not to fight on that card, and he’s the guy that pulled the straw and he’s the next guy up. I get to prove it to everybody again that I’m the best in the world. “I’m in the hurt business. I want to get my belt, and I want to win. I don’t care who I fight. I can fight this guy 10 times in a row, I’ll be motivated. That’s just what I am. It doesn’t take much to be motivated.” Holloway has been on a tear since losing to Conor McGregor in August 2013. The defeat seemed to unleash something in the 25-year-old Hawaiian that took him all the way to the title. He insists he is as driven now that he has accomplished that goal. “The belt is great,” he said. “What comes with the belt? Bigger
