The villians from left to right: Koboruda, Dinasu, Jilfiza, and Pieru holding Doropu
The foot soldiers this time around are Imps.
Their still sleeping mother brought back Magma Golem in ep#11 who revived HellGeros as GolemHellGeros. After Grand Liner destroyed them, the remains of Magma Golem were salvaged as Golem Cards, now used to give added power to their monsters!
In ep#22, Jilfeeza grows to giant proportions, but is destroyed by Max Victory Robo.
Subsequently, in ep #23, Doropu goes into a cocoon and emerges in ep #26 as Salamandes.
