With a large figure, Yoshio is very built, with extreme muscles, out of which the ones of his arms look very disproportionate in comparation with his much slimmer legs. He is the tallest member of his team. He has tanned skin and has semi-long curly green hair that is covered by his helmet and matches his thin green eyebrows above the small pink eyes.
He would usually be seen wearing a loose pilot's helmet and goggles, a ripped purple t-shirt, rosewood fingerless gloves that tuck into his gold wristbands with a lighter gold trims and tight-fitting brown trousers, held up by a brown belt and gray suspenders with matching gold buckles. He also wears knee-leight light brown boots.
Yoshio is a ruthless person, showing no pity or consolations for any actions he commits to anyone. His first assault on the youth only proved it, much to their dismay. However he is open minded, Yoshio had an intent to pursue Kite Unabara through any possible ways; even going as far as challenging Eight who claimed to be Kite.
At some point in Metal Bey City, Yoshio Iwayama uses his Beyblade, Bandid Goreim DF145BS in attacking over dozens of young Beybladers where as a result, their face mark was tainted completely. Searching for Kite Unabara, little did he know that his younger brother, Eight overheard the youngsters upon a trip to the B-Pit. Soon enough though, Yoshio came across Eight, claiming to be Kite Unabara.
Finally figuring out who Kite is, he challenged the so-called "Kite" to a Beybattle to discover who's Bey is truly the Defensive type. Acknowledging this, Eight used Pirate Orochi 145D disguised as Guardian Leviathan 160SB, the true Bey of Kite. As they pitted their Beyblades to battle, Yoshio obtained second-thoughts about "Kite" and "Leviathan" was unable to protect itself from hits whatsoever. Zyro Kurogane and his friends suddenly swept the scene and found Eight; yelling out his name in delight.
Taking a moment to think, Yoshio realized that Eight impersonated Kite and without hesitation, ultimately defeated the "little boy" while Zero and the rest were shocked.
The following day, Yoshio would have his match against Kite. Kite declared he would make Yoshio regret his earlier fight with Eight. Taking place at the Bey Park, Yoshio used a strategy where his Golem would ride close to the Stadium's gates and run towards Kite's Leviathan which could spring back and ram Golem with the pattern repeating. However, even though Kite revealed his true might through Leviathan in their last clash, Yoshio was still stronger and knocked-out Leviathan. Yet as a result, Leviathan sustained heavy damage to its Chrome Wheel which left it unable to battle.
