In the episode "Soul Possession" in the scenes where Xena and Joxer are talking (a flashback to the past) Xena has her new yin-yang shaped chakram (circle shaped blade weapon), which she did not have at that time in the show. When Xena goes off by herself and finds Ares, she has the old original chakram. Then when she joins up with Joxer again, she has the new chakram once more.
