Monster Army

The Monster Army (怪人軍団) is a hoard of kaijin defeated by the Neo-Heisei Era Riders (Aka Double, Accel, OOO, Birth, Proto Birth, Fourze, Meteor, Nadeshiko, Wizard and Beast) who were revived by the Akumaizer to conquer humanity.

History
When the Akumaizer invaded the Underworld, they brought along several defeated Dopants, Yummies, Zodiarts and Phantoms creating the Monster Army, to conquer all of humanity as revenge for being defeated by the Kamen Riders.

However, they all were in for a mean surprise when Gentaro, Ryusei, Nadeshiko (who had traveled back in time by five years) Haruto (from the present date), Eiji (the only previous Neo-Heisei Era Rider to show up) and Double, Accel and Birth (Summoned through use of their Kamen Rider Rings) all showed up and battled them.

After the defeat of the Army, Xatan used the Zeber weapon to use their remaining power to turn their armored vehicle into the Zaiderbeck, which is ultimately destroyed by Fourze Meteor Nadeshiko Fusion States' Rider Ultimate Crusher and Wizard Special Rush's Special Dragon Rush Rider Kicks.

A few left overs who survived the battle were defeated by Kamen Rider Beast Falco Mant.
