Metal Lee

is a shinobi from Konohagakure.

Personality
Metal is a hot-blooded and dedicated shinobi, much like his father and his father's sensei, depicted when he was seen participating in his father's gruesome training regime.

Appearance
Metal bears a stark resemblance to his father with his dark eyes, black bowl-style hair cut, and bushy brows. However, his eyes are noticeably sharper. His likeness is further perpetuated by his attire; he wears a green jumpsuit with orange leg and neck warmer and bandages over his hands. He also appears to wear earplugs.

Abilities
Like his father, Metal appears to specialise in taijutsu. He shows great stamina and strength, keeping up with his father's training and sending an enemy crashing into a wall with a single kick.

Epilogue
During the day of the Kage Summit in Konoha, Metal was rigorously training with his father. As his father emphatically told him that he was in the springtime of his youth, the young man echoes his father's words.
