Lorenzo, known in Japan as Ryusei Gin「銀流星」(Gin Ryūsei) is the former world champion of a "Shooting Game" arcade game and a member of the Society of Light, who is employed by Alexis Rhodes and Chazz Princeton to Duel Jaden Yuki.
Although he is defeated by Jaden, he comes to understand his opponent's definition of a fun Duel. Sartorius punishes Lorenzo for his failure, taking complete control of him and his future and leaving Lorenzo's hair stark white, which Chazz describes as being "reborn".
"Gin" means "Silver" and "Ryusei" means "Meteor".
In the English dub, he speaks with an Italian-American accent and uses such stereotypical phrases as "Bada-bing!", "Mama Mia!" and "Fuggedaboutit!". In the Japanese version, he instead says "zura" after his sentences.
Lorenzo plays a "B.E.S." Deck. With the effect of "Boss Rush", Lorenzo is able to continuously Summon "B.E.S." monsters as they are destroyed, causing extra damage with "Cyber Summon Blaster". The flaw of this strategy, however, is that he is no longer able to Summon in any other manner as long as "Boss Rush" remains in play.
The concept of Lorenzo's cards is derived from the Konami video game series, Gradius, wherein a common element is a boss marathon consisting of about five bosses near the end of the game without any breaks between bosses.
