Here are the top ten strongest characters that are not fused with one another and the list might change on how I feel or when I do something to that specific characters.

1.) Vinnlien

2.) Ghost(That also goes with Gt Ghost and Xeno Ghost as well but regular Ghost is stronger than them)

3.) Ayote

4.) Stanley

5.) Zogmath and Zugan

6.) Daiko

7.) Sunchock

8.) Derrick

9.) Daichi

10.) Geno

Again it might change up on how I feel, let me know what you guys think on the list.
