Sullivan is a character appearing in Pokémon: Advanced Challenge.
Season 7: Advanced Challenge
For many years Sullivan had been trying to capture a Whiscash nicknamed 'Nero'. When he met up with Ash and friends, he hoped that they will help him find Nero, which they do, and Sullivan battled it with his Flaaffy nicknamed Hannah.
After weakening Nero, Sullivan told Ash that he had a Master Ball which will allow him to capture any Pokémon he wishes. When Sullivan threw his Master Ball, he got surprised when Nero all of a sudden ate it. Although shocked that his Master Ball got eaten, Sullivan said that although he failed to catch Nero this time, he will always look forward to catching Nero one day.
