* No canon evidence: The Dragon Ball series, including GT, doesn't provide any information about Pan's ticklishness.
* Character traits: While Pan is shown to be energetic and playful, there's no indication of a specific sensitivity to tickling.
* Fan interpretation: Some fans might imagine Pan as ticklish based on her personality, but it's ultimately speculation.
Ultimately, whether Pan is ticklish is up to individual interpretation and fan imagination. The Dragon Ball series doesn't offer a definitive answer.
