Ponyboy was added to the game in Patch 1.0, and originally increased the effectiveness of Solomon, who was removed later on in Patch 1.0e10. Ponyboy now takes on the function of Solomon himself, directly increasing the amount of Hero Souls gained from Primal Bosses.
If you have Ponyboy leveled at 21 or higher, a new stat will appear under the 'Transcensions' section of the stats page saying that your Ponyboy status is Golden, in reference to the movie and book, The Outsiders.
The developers of Clicker Heroes considered reducing Ponyboy's formula to +(100n2)% in patch 1.0e11, but that idea was scrapped.
