Ronin

Ronin (ne Ronald Collins) is one of the Golden Age Allies of the Ninja. He started off as an anti-hero in the show but eventually became one of the Ninja's friends. 
== Trivia ==
* He died in Chasing Memories: The Start of the Adventure, but was later discovered to be alive in Chasing Memories 3: Actions Have Consequences. 
* He is the first person in the series to adopt a child, not counting the original show. 
** Ironically, he wound up adopting the biological son of Jackson Julien, the older brother of Zane. However, Ronin never discovered this as the child's mother, Jenny, never revealed the real father's name. 
*** This makes Ronin the first character to adopt a Villain Kid.
* Ronin's real name, Ronald, is based on Ronald Weasley from the Harry Potter franchise.
** The name Ronin in the Chasing Memories continuity is actually a nickname given to him by his father before he died.
* The Chasing Memories version of Ronin was originally going to be a one-off villain at the start of the story. However, this idea was scrapped and that version's personality was evolved and transferred to Jackson.
** This version was written between Ninjago Season 4 and 5, so the author had no bearing on Ronin's actual personality.
* Not counting Wu, Garmadon, Misako, the Ninja Parents or Love Interests, Ronin is the 3rd oldest of the Original Allies, Cyrus Borg being the oldest (born 1974) and Dareth being second oldest (born 1983). Ronin was born in 1995, same as Jay and Cole.
* His age in the CM universe differs from the Ninjago canon. It's stated by the show's creator that Ronin is currently in his late 30s. However, in the CM universe he's the same age as Cole and Jay. Since in the CM universe, the events of Season 5 happen during 2015, he was 20 when he met the Ninja rather than in his 30s. At the beginning of the CM series, he is 24, making him 31 when he dies on the Dark Island in 2026.
** The author didn't know Ronin was in his late 30s when writing the story, but chose not to alter the CM canon because she liked the idea of Ronin being younger than Kai.
