Battle Arena Toshinden 2 is the first sequel to Battle Arena Toshinden. It adds three new starting fighters; Tracy and Chaos with the original game's final boss, Gaia returning un-armoured and with a completely new move set. There are also three new bosses and hidden characters raising the total number of fighters to 15 (up from 10). Toshinden 2, on top of additional special attacks for every character, adds several running attacks to each character: the ability to strike a grounded opponent with new ground attacks and the powerful Overdrive attacks that one must fill up a bar by using other attacks to be able to use.
