"Lone wolves may be stronger, more aggressive and far more dangerous than the average wolf that is a member of a pack. However, lone wolves have difficulty hunting, as wolves’ favourite prey, large ungulates, are nearly impossible for a single wolf to bring down alone. Instead, lone wolves will generally hunt smaller animals and scavenge carrion" Wikipedia
'Stronger', yep good, tick. 'Aggressive and dangerous' not good in heavy traffic but if you want stuff done, good, tick. 'Scavenges carrion', wait....... WHAT? Alone this big strong, angry, teeth baring machine with a fluffy covering can only manage to get the dodgy end of the forest foods.
