Not just one entrance, but several John Cena WrestleMania entrances have been all levels of ridiculousness. He's been a Chicago gangster. He's been a marine. He's been serenaded by bands and rappers. But quite possibly the biggest WTF Cena WrestleMania entrance, was when he lined up at WrestleMania 25, surrounded by multiple other John Cena wrestlers! That's right, WWE had seemingly cloned him! In all fairness, it made for a fantastic visual, as the real Cena emerged through a crowd of Cena wrestlers and sprinted to the ring.
