Xiaolin Chronicles is a show that tries to be a continuation, but when it ended after only 26 episodes, would be labeled a stand alone show. While I have seen Xiaolin Showdown when it aired on Cartoon Network, this continuation was made without Warner Bros. As a result, the Shen Gong Wu have been renamed because WB owns the rights to the original names (Orb Of Tornami is now called Orb of Torpedo, and Monkey Staff is now called Monkey Spear),which I understood as this is done by a different company, as well as the change of some voice actors due to it being made in Canada, and Canadian laws require an all-Canadian voice cast (although Tara Strong and Jennifer Hale do return from Showdown to voice Omi and Katnappe).
So, the story is that Omi, Clay, and Kimiko have reached the title of Shuko Warriors (a title Raymundo reached in the final episode of Showdown), and now must find a new Xiaolin Temple after events lead to its destruction. Joining them is Ping Pong, a new Xiaolin Monk who is basically a mini-me of Omi, and they face threats old and new.
So, the thing with this series is it can't make up its mind on whether or not it's a continuation or a reboot. A lot of things have changed, as Dojo is now yellow, the first episode changes the tale of Dashi's fight with Wuya where he imprisons her in a spring, and the characters' personalities have been changed (with Omi getting the worst of it, as he becomes a brat who tends to hog the spotlight, and Raymundo is not the leader of the group). I don't know if these changes were also done to avoid legal issues with Warner Bros., since Christy Hui did return to direct, but it can be jarring at first.
Another thing keeping it down is the new character Ping Pong. He is basically a mini-me of Omi in different clothes, and a good example of what a Gary Stu is, as despite being a novice (and his element being wood), he can use the others' elements without problem (which contradicts an episode of Xiaolin Showdown). Also, Chase Young gets a sidekick named Shadow, who is basically a Villain Sue, only there to be the sexy character. Also, character backstories are different than in Showdown, which can cause confusion.
But one of the worst things in this series is how the Xiaolin Showdowns are done. Now they are done in CGI, and sadly, for 2013 standards, it looks so generic and bland. While the action is good and it is nice to see Xiaolin Showdown brought back, I feel this failed due to the changes it made, hence why Hui would call this a stand alone series instead of a continuation.
