Shinobi World War Arc
During the Fourth Shinobi World War, Tetsu had his chakra drained by a White Zetsu Army clone, which allowed it to impersonate him. The clone used this cover in order to assassinate Tetsu's comrades. It is unclear whether the real Tetsu is alive or not.
- "Tetsu" (鉄) means "iron".
