First appearance of Fisto. In this series, Fisto's backstory was altered so that he is Man-At-Arms brother. Prior to this, there was no relation between them.
The copyright for the Masters of the Universe character Fisto had expired by the time this show was filmed, so his action figure was released under the name Battle Fist. Because the animated character was still under copyright protection, though, he was still called Fisto when he appeared at the end of the second season.
