Cross-Z Magma Knuckle

The Transformation Dragon Fist Cross-Z Magma Knuckle (変身龍拳クローズマグマナックル) is a device used by Kamen Rider Cross-Z to transform into Kamen Rider Cross-Z Magma. Similarly to the Cross-Z Dragon, the Magma Knuckle is inserted into the Build Driver, loaded with its own Fullbottle (the Dragon Magma Fullbottle), to transform into a unique form separate from the Build Driver's standard half-changes.

Functionality
As a standard weapon:

As shown in Episode 30, the knuckle can be used as a weapon. However, to gain massive power, you have to use your palm hand on the front of the fist, putting pressure on it. As for the finisher, you have to place the included bottle for the Magma Knuckle in the hole on the top of the knuckle. Afterward, a punch can be landed on, knocking back any enemy within great distance.

As if Ryuga thought it was useless for a few seconds, then getting attacked by Engine Bro's, he first compresses the front. After landing the powered punch on Engine Bro's, Ryuga realizes he can compress the front to gain power. Since then he uses the bottle and compresses the front again, landing the finisher on Engine Bro's.
