The Secret of Stronger and Tackle! (ストロンガーとタックルの秘密！ Sutorongā to Takkuru no Himitsu!) is the second episode of Kamen Rider Stronger. Following the unorthodox approach the premiere took, depicting the protagonist as a Kamen Rider fighting evil already, this episode revealed how Shigeru Jo and Yuriko Misaki respectively became Kamen Rider Stronger and Electro-Wave Human Tackle.
