Just started out in the game and tamed 4 of these beasts, 3 of them being a squad with a lone female just recently tamed, and yes these guys are literal nightmares to go against to try to tame but once tamed you become the nightmare for the whole island and if you have more than just 1 and maxed lvled you become the true king of the island and all will fear and respect you. (Also its a bit hilarious how when you tame a dino far from your home base, and you have a raft which then the dino climbs onto and doesn't sink it, but its also good for transporting them so that you don't have to worry about them falling behind from running back and forth from you base)
