Must have early game creature. Great knock back means it can take on tough threats by knocking them back before getting hit. On mobile, do the hunt dilo pursuit and get yourself a nice bow. Once you get tranq arrows, nothing is stopping you from taming rexes and spinos. Use your trike to tank and shoot them from far away so you have more time before they reach you. I do this a lot on mobile. And you can use the trike to get narcoberries for making narcotics.
