The Psyma Family (災魔一族, Saima Ichizoku; Calamity Demon Family) is a family of demons whose only objective is destruction and intends to use the Grand Cross planet alignment to bring great calamity to Earth. The Family's matriarch, the Grand Witch Grandiene, hoped to travel to the real world by using the great amounts of "negative energy" that would emerge on Earth when the Grand Cross had formed. Her children, the Psyma Four Siblings, awaited her arrival, sending Psyma Beasts to destroy and finish off human civilization. They have their headquarters, the Demon Palace Psyma Paradico (魔宮サイマパラディコ, Makyū Saima Paradiko), at the North Pole.

The Imps Bodyguards (インプス親衛隊, Inpusu Shin'eitai) are a group of female Imps who serve Denus, with one destroyed by Denus and the other two destroyed by GoGoFive. Pierre revives them as one giant Imp that then divides to become three clones. These clones are destroyed by Max Victory Robo.
The Grim Reapers (闇の亡者, Yami no Mōja; GoGoFive vs. Gingaman) are the namesake foot soldiers of Darkness King Gill that came from the Dark Hell. While they have nigh-invulnerability, their only weakness is the Gingamen's Earth Power.
The Psyma Beasts (サイマ獣, Saimajū) are the demons that the Psyma family use to attack the humans. They start out as cards detailing information about them and Pierre throws the card into the World of Darkness where he says an incantation to bring the Psyma Beast to life. When a Psyma Beast is destroyed, Pierre throws a Regeneration Card on them which makes them grow. The Golem Cards can be used to turn a defeated Psyma Beast into a Golem Psyma Beast. Each of the Psyma Family members have their own Psyma Beasts.
