Did Pan ever go Super Saiyan?

No one knows for sure if Pan ever achieved her super saiyan transformation. You can also tell from Dragon Ball GT that Pan was 14-15 years old, and couldn't do it like the other saiyans (excluding Bulla).

Goku turned super saiyan because of the loss of his best friend.

Vegeta turned super saiyan because of the agony he was feeling that he wasn't the strongest.

Gohan turned super saiyan 2 because of the death of Android 16.

Goten and Trunks turned super saiyan because they were pushed to their limit.

Pan never turned super saiyan in GT because she was never in any of those situations. The closest she ever got was when she was mad that Giru betrayed her.

I believe that she might have turned ssj if Trunks never confirmed that he was not dead when his stone body smashed to pieces, but we will never know...
