Showa knights, as knights of the older generation, often make a shining appearance in the Heisei period to help these juniors, but these older generation of shapeshifters are basically very old, so these knights can not use normal transformations to appear, so there are a lot of props that can summon Showa knights, let's summarize it below
The first thing to say is the Kamen Rider Deck card, which not only allows Kamen Rider Decade to switch forms, but also summons these Showa Knights in kamen Rider Diend's hands.
In Kamen Rider × Kamen Rider Fourze & OOO MOVIE vs MEGA MAX, Kamen Rider Fourze & OOO MOVIE, Kamen Rider Fourze used the Showa Knight Astronomical Switch to summon Knight No. 1, Knight No. 2, Knight and V3, and the same Kamen Rider OOO also used the showa core coin of the showa core coin to come out of Amazon, X and Stronger.
Finally, the lock seed in Kamen Rider Armor, in Heisei Knight vs. Showa Knight Kamen Rider Battle feat. Super Team, Kamen Rider Armor once used the legendary Lock Seed to summon all the knights before Kamen Rider.
