>>149429208The boys won't user their full strength on Sarah, so she gnaws and bites and kicks like a frustrating to deal with child (which she is). the fact the the show makes her out to be super strong is just cartoon slapstick exaggeration of this.
the non slapstick, no holding back power rankings are:
Ed. The masked mumbler episode shows that he is actually stronger than the kankers but wont hit girls.
Kevin, Rolf, Lee. I'm betting Kevin or Rolf could beat May or Marie one-on-one, but the kankers are always together and they're girls.
Marie, May (and maybe Johnny in this tier?)
Eddy, (and maybe Johnny here)
Sarah,
Edd,
Nazz,
Jimmy (not counting his rage buff fight in fist full of ed).
