Wondering if any Star Gladiators Chars exists besides Hayato?

Hello everyone! I have been trying to find if there is any Star Gladiators Chars that came out for the PS1 besides Hayato. I know he exist but I was wondering if the other ones exist. If so any please let me know because I had the game then beat it then sold it and now I regret it. I haven't found that game at all and I would like to either download the chars or have their sprite sheets if the exist. Thanks for your time guys/gals and take care. PEACE!
