Valor Monster

Valor monsters (Japanese: バロール Barōru, "Valor") are monsters with "Valor" listed on the Type/Ability line. They are required for the Brave Summon of a Brave Monster, similarly to how Tuners are required for Synchro Monsters.

Disimilarly to other Tuner-esque monsters however, Valor monsters do not require removing themselves from the field in any way in order to Summon their intended monsters.

The first known Valor monster was "Sonic Knight - Wave the Silent".

Mechanics
Once per turn, during the turn player's Main Phase, if they control a face-up Valor monster, they may perform a Brave Summon using that monster as material. The Valor monster is turned face-down in its Monster Zone vertically, and then that player may Summon 2 Brave Monsters from their Extra Deck whose total combined Arcs is equal to the Level of the Valor monster. While those Brave Monsters are on the field, the Valor monster remains face-down in its Zone, but is not considered to be on the field. At the end of the turn that a Brave Summon was performed, the Brave Monsters are returned to the Extra Deck and the face-down Valor monster is turned back face-up in whatever position it was in when it was originally used for the Summon (when Summoned effects do not activate at this time).

Common Traits
As Valor monsters are intended to bring out multiple monsters within their Level range, they often have high Levels to assist with this. Many will also often have effects that Special Summon themselves to the field with relative ease. Despite their high Levels however, most Valor monsters have relatively low stats as they are not meant to be doing any sort of defending or attacking, as that is left to Brave Monsters.
