Important things that happened

Kamen Rider Ikazuchi (仮面ライダー雷) - Transforms with the Dodo Zetsumerise Key and the MetsubouJinrai's Forceriser
Finisher
Zetsumetsu Dystopia (ゼツメツディストピア) - Shows the kanji Purgatory Powered Lightning (煉獄剛雷).
Zetsumetsu Utopia (ゼツメツユートピア) - Shows the kanji Garbage Powered Thunder (塵芥剛雷)

On screen, there's a written version of Magear as "Magia", but this is just the phonetic spelling error. It's supposed to parallel Humagear.
Raiden and Subaru's product name is Uchu Yaro (Uchuu Yarou) which just means "space guy". Raiden means "lightning and thunder" while Subaru is the Japanese name of the Pleiades star cluster.
