The Four Season Bladers are a group of four Legendary Bladers that act as a key, along with the Solar System Bladers, in order to defeat the God of Destruction, Nemesis, and prevent it from ruling the world. They were first revealed in The Bladers of the Four Seasons. However, Kenta Yumiya obtained the summer constellation Star Fragment from Ryuga, making Flame Sagittario C145S evolve into Flash Sagittario 230WD. Ryuga and L-Drago Destructor F:S disappear afterwards.
Chris is the only member to be a new character, and to have previously allied with Nemesis.
Balance is the only Type not featured within the Four Season Bladers, as both Gingka and Ryuga use Attack Types, Chris and Kenta use Stamina Types, and Kyoya uses a Defense Type.
