Tannin is a Vermillion warrior.
After stealing metal from the city, the Vermillion Army traveled in underground tunnels to their new headquarters. They also attacked the power source to cause a blackout.
They succeeded in retrieving the Time Blade, but Jay came to rescue the ninja and his mom and the commanders slowed them down.
Once freed, the ninja used the Time Blade to slow the Vermillion down, and the ninja got away.
The Vermillion arrived at the temple and attacked the ninja. They were able to steal the Slow-Mo Time Blade.
Tannin was on the lookout for the ninja but didn't realize Jay and Cole passed them. Later, they heard a loud sound and went in to check. They were able to outnumber Jay and Cole but when Lloyd and Zane helped, the Vermillion were defeated.
The Vermillion chased the ninja and regrouped at the dome when they left. Later, when the ninja were granted access to the Iron Doom, Jay talked and blew their cover. The Vermillion were instructed to attack them, but they were run over by the Samurai VXL. They continued to chase the ninja to the Iron Doom. When Machia told the Vermillion to go to the Iron Doom, they stopped fighting.
Machia prepared the Vermillion to fight the past Elemental Masters. During their battle, the Vermillion easily outnumbered the Masters. When they are battling, the snakes are destroyed and fused into the Iron Doom.
