Banette first appeared when it sprung out of a car that came from the Team Rocket airship when Silver's Gyarados used Fire Blast on the car. It used Shadow Ball in retaliation for what it did. Causing a massive amount of damage to Gyarados, Yellow healed it, but once it healed, Banette used Snatch to take the energy from Gyarados. Once Sird and Orm introduced themselves, Sird suggested a Multi Battle, which Silver agreed, to the panic of Yellow. Sird used it in the battle alongside Orm and his fierce-looking Jumpluff. Banette attacked Double-Edge, with Gyarados using Fire Blast again, but Banette dodged it, ending up back in front of its trainer. Due to the revelation stated by Sird, Silver's defenses were down. Sird took advantage of this and had Banette take control of it by having Silver look into Banette's eyes.
On the airship, she had Banette lower Silver, so she could dress him a ceremonial outfit to crown him the new prince of evil.
