Hilarious in Hindsight: Not only would Kamen Rider Kabuto have two lead Riders with similar colors and beetle motifs as the Gouraiger, but their personal weapons are also similar (except that KuwagaRaiger's scissor claw can't be seperated).
Also Nanami's career aside of her ninja-ness. Starting out as an enka singer and eventually exploding as a famous Idol Singer and multi-talent star? Well, why does it reminds us to a certain someone in real life named Nana Mizuki? In hindsight, because during the airing of Hurricaneger, Nana Mizuki hadn't really exploded as a true star.
Ho Yay: Some fans take Yousuke and Ikkou this way, particularly when Yousuke is deliberately poisoned to save Ikkou's life.
