I know its made to just be cool, but I have an idea that could make it cool and useful.

Its roar should have an affect on raptors only. When tamed Raptors here it, they get a boost similar to the yutyrannus roar. When wild raptors here it enough times, they fight for the indominus for a time, again, like carnos for a yutyrannus roar. Another cool thing would be to make it so if raptors that belong to another tribe hear it enough times, they will turn for a minute against there owners. A way we could tell if the Indominus was controlling enemy raptors is if we made their eyes glow like the Indominus when it is a baby and in a rage.
