The words Arachna Power are an incantation and mantra commonly utilized by the Spider Riders to call upon the Spirit Oracle to gain their unique armor and weapons (along with such things for their Spiders). Thus granting them tremendous abilities, usually in the form projections of visible energy, as well as the ability to preform a vast number of amazing feats.
- In the Japanese version, the original phrase was simply "It's Alright" (結果オーライ Kekka oorai).
- In the episode Memories of Champions, Corona explained that the very first Spider Rider was called Arachna. So it's possible that the mantra was named in his honor. Though this is mere speculation.
