Seventh Spear, Sandaaru, is Tau Zant's most powerful and wicked soldier. Leader of the Seven Darkness Lances, Sandaaru is a vicious shark-like alien known for destroying entire worlds. Coming to earth to assume leadership of Jakanja's military, he immediately shows himself as a more brutal and cunning foe than the Hurricengers have yet faced, even killing the ninja Lady Gozen to steal a magic gem from her. Betraying his own side and eliminating fellow Lances when they have fulfilled their purpose, Sandaru even turns on and kills Tau Zant before attempting to hijack his plan to use the Evil Force to wipe out all life and become a god in his stead.
Family-Unfriendly Aesop: Episode 11 seems to imply that "reality" is more important than "dreams" note The Monster of the Week was trapping people in their (good) dreams., and that the viewers somehow need to "accept" that. On the other hand, this was likely unintentional.
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.
