Bow of Hercules (National Treasure)
He has messy brown hair, freckles on his face and a mole beside his left eye. Samuel has straight small teeth, while at the same time still wearing his braces.
Samuel is the leader of Team Argentina, but has been shown to act on his own when he went out of his way to test Jin Mo-Ri's (Hui Mo-Ri's) strength during a street fight after his soccer game. He has been shown to be rude and cynical towards his opponents and even goad them by calling them weak.
He has been shown to go berserk if he is looked down upon, which maybe due to his childhood scars of people calling him, rat, useless, and ugly. This is shown when Hui Mo-Ri made him say quit, which made Samuel go berserk.
Despite his shortcomings, Samuel also exhibited some trait that made his ancestor famous such as bravery and heroism. He has shown himself to be brave enough to save Anna from being killed by Zeus, despite Zeus being a powerful God and had killed most of world tournament participants. In his childhood he attempt to rescue elderly woman from a falling object, which cost him both of his legs.
When Samuel Rosinante was a child he was mocked by all his peers, as he was unfit and unskilled.
One day he saw a large object tipping over, about to land on an elderly woman. Rushing to the rescue, the incident caused both of his legs to be crippled, ruining his life further. Completely shattered and feeling useless, Samuel cried and fell over one day, when he encountered his ancestor: Heracles. Heracles then offered Samuel his power, which he accepted.
It is unknown how powerful Rosinante's strength is without his charyeok, as he fight mostly with his charyeok enhanced strength. However, it can be presumed that he has some physical powers of his own, being lineal descendant of the legendary Heracles.
Heracles: Samuel's charyeok and his ancestor. Heracles mostly gives him physical power-related abilities.
When powerlenderized, despite not having training and control over his form and thus an inability to access its full potential, he was still strong enough to lift an expanded copy of Ruyi Jingu from Hui Mo-Ri, and even grip it hard enough to stop it from expanding.
Physical Enhancement: Heracles give Samuel physical power beyond that of human.
- Enhanced Strength: With Heracles, Samuel's raw strength is on par with that of a god, allowing him to lift a copy of Ruyi Jingu (with difficulties) and casually overpower Jin Mo-Ri's clone. In Powerlenderization form Heracles allows him to lift it without problem and even swinging it around in its large form, also, His grip is hard enough to stop it from expanding.
- Enhanced Endurance: He exhibited high pain tolerance as despite his leg being flattened by Zeus while saving Anna he doesn't scream or appear to be in pain. In powerlenderization his endurance was great enough to shrug off the pain of being striked by lightning from copy of Kinto-Un and even retained enough focus to summon a national treasure.
- Enhanced Durability: His durability allows him to tank most of Hui Mo-Ri's attacks, especially in Powerlenderization.
- Heaven Slam: Samuel takes a hold of his opponent and slams them to the ground hard enough to make craters.
- Gigantic Earth Suplex: Samuel throws his opponent with enough strength that their bodies can even break pillars.
- Dropping Hydra: In the past Heracles used this technique to defeat Hydra by grabbing one of its head and throw it over his shoulder. The force of the technique when used is powerful enough for surrounding area to shake like an earthquake. Samuel gain access of this technique in Powerlenderization.
The staff has been shown to be more durable than the staff given to Hui Mo-Ri by Seo Han-Ryang, as the latter shattered when the two staffs collided with one another. It is likely that the real staff used by the historical Heracles is summoned in place when he is powerlenderized, but no confirmation is given.
The bow has been shown to be very destructive in power, but not as durable as Ruyi Jingu, when Hui Mo-Ri shattered it with his staff. After he accidentally achieved Powerlenderization, he gained the real Bow of Heracles, the one forged by Hephaestus, blacksmith of the gods.
Nemean Lion Pelt
Heracles killed Nemean Lion during one of his labour. Samuel can summon it in his powerlenderized mode. It is strong enough to resist Hui Mo-Ri's Nabong Needle Ryu techniques while in Lord of Heavens Mode. Hui Mo-Ri commented that it protected Samuel Rosinante's lethal spots during powerlenderization.
