Depending on How you choose to break this down, there are actually 21 characters....If you only count every Angel from his or her respective universe separately and not as a whole and count the Grand Priest Separately...

( This doesn't count Zeno's guards) If you feel I'm wrong, you do the math, and see if you come up with a different answer

You got a total of 13 Angels, 4 Saiyans, 1 Namekian, 1 Destroyer God, You got Frieza, and finally there's Zeno.
