Each "Pendulumstatue" has the name of the color of the corresponding Attribute (White and Yellow being both LIGHT) and something related to one of the Types. Each color is also representative of the types of monster cards in the game, Red being Effect, Blue - Ritual, White - Synchro, Yellow - Normal, Purple - Fusion, and Black - Xyz. Their artworks depict the object in the name with that color scheme. They all possess a Level and a Pendulum Scale summing 13, with the difference between the Pendulum Scales of each colored pair always being 6, and their ATK/DEF is equal to their Level x 100.
"Pendulumstatues" are all Rock, and share the Monster effect of searching another one of them when Pendulum Summoned from the Extra Deck. Each of them has the Pendulum Effect of boosting the ATK of the related Type by 200 or 300 (except "Purple Shield", which raises DEF, "Red Fiend", which supports FIRE monsters, and "Black Sun", which supports DARK monsters).
The Pendulum Effects of each monster also resemble the effects of the earliest released Spell Cards in the game (such as "Violet Crystal" or "Beast Fangs"), granting a small ATK (or DEF) bonus to a specific type of monster. This is fitting, as these are, in the ARC-V universe, the earliest released Pendulum Cards, and were given out to ease the players into the mechanic.
