Alvin

Alvin Sandberg, also known as Alvin The Sandmaster or simply just Alvin, is the main titular protagonist of Alvin: Legend of The 7 Rings. He is a juvenile teenager who wants his dream of becoming the Grandmaster of Sandria come true by collecting all 7 Legendary Rings.

Overview
Alvin is a 15 year old juvenile teenager known for living with his loyal grandfather and is very skilled and fights with threatening foes who dare gets in his way. However, Alvin wants to become the grandmaster of the big royal country of Sandria like his grandfather since there is no other person to claim the royal throne of the Sandria Palace.

It was said that people can achieve the title of being a grandmaster if they do something that seems 'rare' or 'incredibly impossible' such as taking down a titan or do 1,000 push-ups. Upon learning this, Alvin thinked the impossible and is raring to go as he must become the grandmaster of Sandria by joining the Xandria guild, team up with the likes of Ryuko and Bon Lupin IV, and go on wondrous adventures of claiming the powerful and colorful 7 Legendary Rings, energetic rings that have sensational emotions.

Personality
Alvin is shown to be rowdy, energetic, very nice, and always bright. He always have his head up and never backs out on anything (unless he needs help). Because of this, Alvin never gives up, which is one of the reasons why he wants to become the next grandmaster of Santrial and likes to do things that seems 'impossible'.

Despite being happy-go-lucky, Alvin is sometimes shown to be rude or mean if things don't go right or if a situation gets dire (to which he spawns Red Alvin, a negative counterpart of him based on his negative emotions). When someone mentions about his mother and father at one point, Alvin loses it and he beats them. This is because that his mother and father have a very bitter relationship and they went away, leaving Alvin with his loyal grandfather. However, despite having a tragic past, Alvin never let anything so tragic/upsetting haunt him and moves on to be more opened and wondrous.

Alvin is shown to be having a love interest towards his crush Ryuko, a girl with fox ears. However, she doesn't follow Alvin's perspective. Not only that but he is also shown to be rivals with Bon Lupin IV, the fourth child of the Lupin family. Bon is shown to be more skilled and powerful than Alvin, which annoys him and makes Alvin train more often and become extra powerful and skilled than Bon.

Alvin also has a huge appetite. When Nadine first introduce him and his friends with her superb skills of making and buying food, he grew into a rather gluttonous eater who eats food to get stronger. His favorite meals are donuts and chicken sanwiches.

Superpower
Sandmaster - Alvin has the ability to do amazing combat and abilities with anything from sand (or dust/snow)

Abilities

 * Sandstorm Arms - This allows Alvin to make his arms go hard and engage in combat.
 * Sand Surfer - Alvin can surf and run fast at land on high speeds.
 * Sandstorm Bolt (+ 10/30/50/70/110/1,100,000) - Alvin performs a extreme punch in both his base form and his boost form. However, the punches in his boost form is powerful enough to create a sand shockwave. Alvin can upgrade his Sandstone Splinter by counting to 10s in odd numbers. This is Alvin's most used ability and his signature super attack
 * Sandbody - Alvin can turn his body into sand and can go flat at times. If a person steps on him, it doesn't work. However, when his opponent steps on him, he lends them in like quicksand and shoots them out in the air like a cannon. He can also move while in this state. This is Alvin's least used ability.
 * Sexybody - Similar to the Sandbody ability, Alvin can transform himself into a sexy pigtailed girl in a orange bikini.
 * Sandball - Alvin can make and throw sandballs.
 * Manifest - Alvin can manifest inanimate objects and living creatures when in boost mode, such as making a sandboard and a living sphinx.
 * Sandstorm Thunder - Alvin's ultimate (final) super attack. This move is the strongest move in Alvin's arsenal, which involves Alvin taking to the air, and then using dust to propel himself in a circular motion to create a sandy and electric tornado. This tornado builds up oxygen to fuel the incoming lightning explosion. After colliding with the target, Alvin releases the powerful aforementioned bolt explosion.
 * Super Sandstorm - It's the same as the original, except that it is more power by using the Red and Yellow Legendary Rings.
 * Sandstorm Omikron - A incredible ultimate super move created by both Alvin and Ryuko by teamwork. This allows both of them to combine their ultimate super attacks and unleash them within a mass destruction. This has got to be Alvin and Ryuko's biggest (but not the strongest) ultimate super attack they've made.
 * Sandstorm Beam - A impressive ultimate super move created by both Alvin and Bon by teamwork. This allows both of them to combine their ultimate super attacks and unleash a lightning and dusty explosion with a aura beam charged and blasted at the same time. Unlike the Sandstorm Omikron, this has got to be Alvin and Bon's greatest and strongest ultimate super attack they've made.

Relationships

 * Aaron - Alvin loves Aaron because he was a grandmaster of Santrial at one point of his life, which inspires him to become one.
 * Ryuko - Alvin has a love/hate relationship with Ryuko at the beginning of the series. Despite his juvenile behavior, Alvin tries to get along with Ryuko and hopefully be together. In Ryuko's response, she finds that complicated, much to Alvin's dismay. In several chapters later, Ryuko became a more better and nicer character to Alvin since his juvenile traits are wasted ever since he began his journey to become the next new grandmaster of Santrial. Because of this, Ryuko begins to be less hostile and negative to Alvin and hangs out with him for the first time, which horizons their relationship. Ever since Alvin got the Dark Legendary Ring and faces his negative emotions, turning him into Shadow Alvin, Ryuko gets scared but has to get Alvin back to his base form by forcing him to put on the Pink and Aqua Legendary Rings to finally face his negative emotions. This finally proves that Ryuko has changed to a good person, to where she starts to love Alvin, much to his pleasure. Sometime after Alvin became the new grandmaster of Santrial, he and Ryuko marries and lives together in the Santrial Palace.
 * Bon - Alvin and Bon didn't get along ever since at the beginning of the series. Bon thinks that Alvin will never become the next grandmaster because he's too childish to do so. Alvin disagrees because he has faced many dangerous events behind him in the past (which is true). While Alvin tries to collect the Blue Legendary Ring of fear, Bon halts him so that he can get it. The two engaged in a massive fight until Bon manages to win and claim the Blue Legendary Ring of Fear, which annoys Valentine. When Alvin was having a hard time fighting with Demetria over the Yellow Legendary Ring of Energy, Bon begins to change from being selfish and helps him and tries to distract her with fear, which eventually helps Alvin annihilate Demetria, much to her shock and fears. Upon Demetria's defeat, Bon starts to be more likeable to both Alvin and Ryuko.

Trivia
