How many minimum characters are needed to defeat Frieza and Cell in one hit?

Write the least powerful character capable of defeating Frieza (100%) in one hit, then a character that one-hits that character, and so on until you reach SPC.

I have 13 characters:

1.- Future Trunks SSJ (Debut).

2.- Android #20 (Peak).

3.- Future Trunks SSJ (Android).

4.- Android #18.

5.- Super #13.

6.- Imperfect Cell (Post Human).

7.- Semi Perfect Cell (Initial).

8.- Vegeta ASSJ.

9.- Perfect Cell (Suppressed against Vegeta).

10.- Vegeta SSJ (CG).

11.- Goku MSSJ (CG).

12.- Perfect Cell (FP).

13.- SPC.
