When Wedding Dress Org was on the loose, Danny went to the flower shop to warn Kendall, and discovered that she had another suitor. The Org did show up at one of Kendall's jobs, and when Danny morphed to fight it, Kendall discovered that he was a Ranger. The two agreed that they could not be together with Danny's life as a super hero.
With Master Org defeated, Danny and Max retired from their lives as Rangers and were able to party around the world on a long vacation.
When he becomes the Black Ranger, Danny's own natural strength is enhanced, giving him the power of the Iron Bison.
