Do you, like me, think Sharpteeth are too dumped on when, if you think about, their main "crime" is that they need to eat? (I get that them going after kids like the Gang of Five seems a bit mean on their part, but, maybe the kids were all they could find at the moment.)
Anyway, after finding Chomper and falling so in love with him (we have much in common), I feel that we should at least see a Sharptooth or a part Sharptooth have us see things from their point of view and so we could get why they do what they do.
That was actually part of the reason I created Ptero in my fanfic, to show a half Sharptooth who thinks he's a full Sharptooth who hunts, yet he eats every bite because he knows what it cost the animal to be his meal and will sing, when hunting, well, at one point we see him singing, that he only is doing it as he has had no food all day and that he wants to go to bed with something in his stomach and that when he is not hunting that he is very sweet, which he mostly is. He also thinks that it is sad, when he gets his meal at the end of the song, that another poor beautiful creature had to leave the world so that he could stay on it.
(Ptero also eats leaves, so he can still get the sympathy of viewers who favor Leaf Eaters.)
Also, I brought in another whole subset of creatures called Bothteeth that are kinda like Ruby, except, unlike Ruby, they eat other dinos in addition to plants whereas Ruby just eats clams and plants.
These type of dinos could be more hated than Sharpteeth as they are free to eat plants all their life or plants and clams but would willingly choose to eat their fellow dinosaurs (a choice most Sharpteeth, possibly including our friend Chomper, don't have.).
