Spryzen (スプリガン, Supurigan) is the main antagonist of the anime/manga series, Beyblade Burst Evolution.
Spryzen's appearance is that of the avatar for Spryzen Requiem, wielding a halberd with the Spryzen crest, the same of which can be seen on his armor.
The personality of Spryzen is unknown, but can probably be seen through Shu Kurenai when he is possessed by his bey.
Spryzen Requiem was a Beyblade that formerly belonged to Shu Kurenai. It overwhelmed Shu Kurenai with its power and thus brainwashed him into becoming a power-hungry and ruthless blader.
