Energy Items

Energy Items (エナジーアイテム) are medal-like power up items created by Game Areas, whenever any person activates a Rider Gashat, and are hidden in certain places in the Game Area. When Ex-Aid collects one, he says "Item Get" (アイテムゲット).

Initially hidden inside Gashat-specific item containers and only seen when released and used, Perfect Puzzle's debut in Episode 15 caused them to start generating sitting or floating out in the open in large numbers. As of Episode 38, Masamune Dan/Kamen Rider Cronus put the Energy Items under his oversight, and they stopped being generated in the battlefield, now only available through the case he carries, until Kamen Rider Para-DX reclaims the Items from his possession in episode 40.

Locations
Depending on which games and corresponding Gashats are used, Energy Items that are generated can be hidden in various container items, though not every container has one: So far, Gashats used to access Level 3 or Level 5 forms have not been seen to generate any Energy Items, simply generating a Gamer instead. However, there are a few special cases: Since the debut of Kamen Rider Para-DX and his first usage of Perfect Puzzle's power, the Energy Items are kept revealed by default, all Gashats thereafter spawning only loose Items without containers. However, the Kyuranger crossover episode featured a Chocolate Block prop in the background, likely as Perfect Puzzle hadn't been used in that universe. Why they generated loose in the Kamen Rider Ex-Aid "Tricks": Kamen Rider Genm specials only to return to item containers for a few more episodes continuity-wise, however, is a mystery.
 * Mighty Action X/Proto Mighty Action X/Mighty Brothers XX: Energy Items are hidden in chocolate blocks.
 * Taddle Quest: Energy Items are hidden in treasure chests.
 * Bang Bang Shooting: Energy Items are hidden in metallic drums.
 * Bakusou Bike: Energy Items are hidden in trophy stands.
 * Dangerous Zombie/Taddle Fantasy: Rather than (or in addition to) generating Energy Items, this game generates Bugster Viruses. This is likely due to the player character being a villain.
 * Perfect Puzzle: Energy Items are generated in the open instead of being hidden by default. It can also turn all Item containers from other games into Energy Items.
