Silver seen as a viable threat, more than Blue was to Red, and has actually won battles while AJ's team was at good health. His Gastly and its evolutions caused a good amount of grief to AJ, being able to curse LazorGator, to which eventually made him faint, allowing Silver to win. He also challenged AJ at the end of Victory Road, with AJ's team crippled from the trials before.
He later returned in Run 19 (Pokemon Prism) as the Warden of Eagulou City, having successfully locked up a member of Team Rocket and Pallet Pink, a member of the antagonistic team Pallet Patrol. His Meganium had been replaced by Hitmontop. He gave Cyan a Star Badge and the Flash TM he had obtained from the Elder in Sprout Tower.
