Battle B-Daman

Yamato Delgado and Gray Michael Vincent

Gray and Chrome Zephyr

Gray challenges Yamato

Gray debuted as a character who wanted to capture Cobalt Blade but was defeated. Afterward he was sought out by Yamato and the two had a rematch that ended in a draw.

After several friendly moments the two became acquainted and trained and even lived together with Bull for a while. He went out and showed Yamato the world of B-Daman, training him and showing him the basics. Everything was perfect in their friendship until Wen and Li openly challenge Yamato and his secret is revealed.

The secret is that Gray is actually working with the Shadow Alliance, the same people who threatened Yamato's town and fellow B-Da Battlers. Little does Yamato know, Gray is only with them so he can free his little sister. It is also revealed that he lost to Yamato on purpose to test his abilities. He is later seen with Wen, Li and Ababa at the Winners tournament scoring a perfect 100 at shoot the gap, regretting that he has no one to share it with. In the semi-final qualifying round Gray defeated a skilled B-DaPlayer named Mickey Mookers. Gray is shown to not have totally turned his back on Yamato, shown when he helps Yamato get the parts to fix Wing Ninja and several times when he is cheering on Yamato's team and discouraging the Shadow Alliance members.

The Long Awaited Rematch Yamato vs. Gray

Gray is now put to the test when he must face Yamato in the first round of the Elite Eight Semi Finals. Gray trains vigorously for he match the next day until he meets Yamato and his gang in an ally way where the two share a surprisingly friendly conversation on how they both say they are going to win. Their match begins but not without Yamato looking discouraged and saddened. The stipulations of their match work in Gray's favor as Yamato is not able to balance himself on the moving conveyor belt and easily knocks down many of Yamato's pins.

During their match Gray figures out that Yamato knows the truth but still tries to force Yamato to seriously B-Da Battle him and he reflects on his memories with Yamato. But after Yamato refuses to battle him seriously he uses his wide server to quicken his victory against Yamato. Yamato stands by until Gray uses his chrome impact slam to end it all, then Yamato rejoins the battle and retaliates with his cobalt power blast and the match ends in a tie.

After Liena defeats Terry he confronts her but to no avail telling him that she never knew him, to his surprise and extreme displeasure, but is re encouraged by Yamato and all of his true friends. During their search for Liena, Yamato confronts a Shadow Alliance Trainer named Goldo, where he learns the Shadow Alliance captures the spirits of B-DaPlayers. Terry and Bull decide to hold off Goldo while Yamato and Gray continue their search. When they find Liena, she assaults Gray for being a traitor.

After Cobalt Blade is successfully made the gang returns to the winner's tournament where Liena gives up her spot against Yamato to Gray. The two have a incredible match that was very close but Yamato came out on top.

Chrome Raven

Gray and the rest of the gang begin to return Gray and Liena to their hometown of Wintune but are surprised when Wintune has been wrecked and made into a Ghost Town. This upsets and puzzle's Gray and Liena. After returning to Cowtune, Gray is relieved to see Liena happy and content with helping Mie like everyone else. This relief is short lived due to an attack of a nearby town called "Carlitoville".

Gray holding Chrome Raven

Gray and Chrome Raven

In Carlitoville it is revealed that a gang known as the Longhorn Brothers of the Shadow Alliance not only attacked Carlitoville but attacked Wintune as well. Sadly Yamato is unable to battle them due to Bull's shoddy repairs, this causes Bull to battle in his place and eventually be solemnly defeated, destroying his Helio Breaker. Saying that the gang wishes to take out traitors like Gray they set up a rematch with Gray as the challenger in one week. After the challenge Gray is overly distracted and nervous about his match, unfocused in his practice match with Terry and very distant from the group when he is training solo. When Bull tells Gray that his Chrome Zephyr is no match for News Gray becomes very angry and heavily insults Bull telling him he didn't take care of Helio Breaker. One week passes and the Longhorn Gang storms Cowtune. With the help of Terry Gray is able to take out the first wave of members. But after Terry is knocked out by unfair battle mines, Gray is barraged by News' incredible strength, breaking Chrome Zephyr apart. Before it was destroyed Bull comes and gives Gray an updated Chrome series B-Daman known as Chrome Raven.

Gray now easily defeats the rest of the Longhorn gang minions with Yamato and even one round with News goes off well, forcing him to call Salz for help. With the help of Salz and holding the villagers shadow cell prison hostage Gray and Yamato are backed into a corner, but Terry regains conscientiousness and encourages Yamato, this allows Yamato to adopt moves from his friends and worry News and Salz making them weak and cause Marda B to appear. Marda B grants News and Salz new powers by turning them into monsters giving Yamato and Gray a bit of trouble. This bit of trouble becomes a huge problem as Yamato and Gray are backed into a corner, being barraged by battle mines and b-daballs, Gray and Yamato appear to be defeated.

This does not stop them though, they all decided to sneak out during the night leaving behind Liena, Mie and Armada. Gray chose to leave behind Liena for her own safety but still worries about leaving her without him. During their journey they meet a child who Terry has nicknamed Gill.

The Battle is a stalemate until Gray is enraged when Cain breaks a B-DaBall that was very special to Joshua. Gray gains the upper-hand in the battle until Cain reveals his new B-Daman Lord Cavalry.

After Cain and Joshua left the gang headed to the B-Da Worlds last known stronghold, Neon City. In Neon City Gray encourages Wen to not give up looking for his brother. After they all rest up Yamato and the gang decide to go and challenge Marda B before he and his army reach Neon City.
