Pokemon

The Pocket Pet Trainer is not a recognized character within the main Pokemon franchise canon. There is no character by that name in the core Pokemon games (Red, Blue, Yellow, Gold, Silver, etc.), anime series, or official manga adaptations.

The term "Pocket Pet Trainer" is a general descriptor that could apply to any character in the Pokemon universe who captures and trains Pokemon, which are often referred to as "pocket monsters". Ash Ketchum, the anime's protagonist, and the player characters in the video games are prime examples of individuals who could be loosely described as Pocket Pet Trainers.

It is possible that "Pocket Pet Trainer" is a name used informally within certain fan communities or perhaps in a fan-created work (fanfiction, fan game, etc.). Without further context, it's impossible to identify a specific official character associated with that designation.
