For me, from best at top to worst at the bottom

1. Axel (only one who actually seems to train in martial arts seriously and is strong and fast)

2. Caleb (can literally punch a boat apart, Axel still beats him because unlike the boat, Axel can dodge and hit back)

3. Scary girl (Athletic and able to randomly a bear)

4. Nichelle (Post season 2 of course, season one would probably have her close to bottom)

5. Bowie (Fairly Athletic and said he was top wrestler at his school, so very good grappling skills)

6. Raj (Above Wayne because he atleast knows he needs to avoid getting punched

7. Wayne (strong and fast but not very viscous, unknown what his fighting skill is)

8. Ripper (I feel like he's been in a few street fights, and definitely isn't a complete pushover in physical challenges)

9. Priya (is quick and strong, but was unable to stop Ripper from using her as a human shield)

10. Julia (Priya beat her up in season 2)

11. Damien (definitely tries to talk his way out of conflict because he's timid)

12. Millie (did wrestle an alligator, but rest of the time she's not very physically competent)

13. Emma (Judging by her rage mode, it loomed as if she doesn't deserve to be at the bottom)

14. Zee(Definitely probably doesn't know how to fight and isn't exactly Athletic, reach is his only strength)

15. Chase( it's Chase)

16. MK (very weak and unathletic, doesn't seem to know much about fighting and her size definitely doesn't help)
