Bowser Jr. (2000–Present) is the main son of Bowser. He was considered to be the worst character in YTP yet.
Bowser Jr. got upset because his fanbase was leaving him and by 2008, his fanbase was gone. He also stopped acting in YTP'S in 2009. In 2010, Bowser Jr. was sent to the Mushroom Kingdom Hospital after attempting to kill himself. On December 23, 2010 he was given away to his Uncle Koopa because Bowser was a piece of shit father.
In 2013, Bowser Jr. was sent back to Bowser when his Uncle Koopa committed suicide and shortly after, he auditioned for a YouTube channel called SuperMarioLogan so he could gain back his fanbase.
