Spryzen, known as Spriggan (スプリガン, Supurigan) in Japan, 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.
Before Evolution, Spryzen was an unsentient avatar. After Shu's, as Red Eyes, battle with Lui, Shu underwent the Requiem Project where he saw his opponents before meeting Spryzen who promised to help him attain power and created the "Ultimate Beyblade": Spryzen Requiem.
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.
