It's only fitting, though, that "Superman" is the one to pass him up.

That's right, not content with having one of the most badass names on the planet, Clark Kent Apuada chose to do one better by breaking a world record set by Michael Phelps back in 1995.
"That was one of my dreams - to beat Michael Phelps's record - since I was 7", Apuado said in the above video.
Swimming at the Far Western Long Course Championships in Moraga, Calif., Apuada finished the 100-meter butterfly in 1:09.38, besting Phelps's 23-year-old, 10-and-under meet record of 1:10.48 by more than a second.
Clark already has his eyes on the not-too-far-off Summer Olympics.More news: 80 injured as plane crashes after taking off from airport in Mexico
Apuada's time slashed over a second from Phelps' record, which had gone unbroken even as the competitive swimmer went on to win numerous Olympic medals. He is certainly the most decorated, as he has 28 Olympic medals, 23 of them gold, to go with his 33 World Championship medals. "He's always stood out, he's just, he's kind of a savant of sorts".
'I deal with it really well, I just have to balance, ' he told CNN.
Apuada, who has been swimming competitively for only four years, won all seven of his races, including the 50- and 100-meter freestyles, the 50-meter fly, the 50- and 100-meter backstroke, s and the 200-meter individual medley.
He added: "Dream big, and always focus on your dreams and have fun".
According to CBS Baltimore, he added: "I love swimming because I have a lot of people supporting me, and my coaches are always there for me and my parents are always there".
