The way I see it, the Twilight Cage is sort of like Precure Hell (a place where the fallen spirits of darkness gather). Even most of the primary villains are either masses of darkness and hatred given form (Getsuyobi and Mokuyobi essentially being a sentient Zakenna and Uzaina respectively), or a previous threat revived in a new form (Kayobi being the Smashground competitor who was defeated at the end of Cyberverse, Kinyobi being made from the same substance as Fusion, and Doyobi and Nichiyobi literally being Stop and Freeze from Go Princess remodeled into a new form).

The only exception to this rule is Suiyobi, who was Yogantsume's daughter from Dinosaur World who initially had a different name before being recruited by the Twilight Cage in episode 11, therefore making her the only antagonist in the season that never previously died.

Also, each general has their own unique way of making monsters that's somewhat reminiscent of their season of origin:

Mokuyobi (and on some rare occasions Getsuyobi): Can create Yabaina from things other than people such as objects, animals or plants (as was the case in basically every season prior to HeartCatch)

Kinyobi: His Yabaina are born from pieces of his own body and can take multiple different forms, many of which are reminiscent of past Precure monsters ala the Dark Matter from Prism Hearts.

Suiyobi: Tosses her personal Kyoryupon that then injects itself into someone and something and transforms them into a monster (kind of like how her dad made Saurrows in Dino Spirits)

Kayobi: Tries to willingly recruit people to his side through a variety of methods or uses whatever spare darkness he finds in the depths of the Twilight Cage (kind of like how the monsters in Sporty were all willing competitors)

Doyobi and Nichiyobi: Retain their Go Princess ability to reveal people's dreams, then imprisoning them inside the resulting Yabaina as a living battery (so sort of a fusion of the Getsuborg from Go Princess and the Desertarians from HeartCatch).
