Karl Fanaloka is from the All Hail King Julien Netflix series.

He's from Xiaolin Chronicles and even though I don't like Xiaolin Chronicles, he's the only part of the reboot I liked, because I liked how my favorite character Jack Spicer had a fan. Tiny Sim can interact both with Xiaolin Showdown and Xiaolin Chronicles, personally, I'd like to see what he's be like in Xiaolin Showdown the original series.
