Saiark

Saiark (サイアーク) are the main monsters of Happiness Charge Pretty Cure! and are made from the dark reflections of people's souls. They are usually summoned by the generals of the Phantom Empire when they find a likely victim. If the Cures fail to defeat the monster, the person can be stuck like this forever trapped in a dark mirror.

Appearance
The monsters appear as large minions of the generals, usually taking on a trait or two of the victim's darkness. They wear red sunglasses and scarves that have a certain color depending on who summoned it: green (Namakeruda), pink (Hosshiwa), yellow (Oresky), white (Phantom) and purple (Madam Momere). There are also ones with bluish-gray scarves, but it is not known who summons those. Sometimes, they have different styles in any condition.
