It just needs a TLC badly.
Maybe a boost in size and an ability where it can sense anything below 60% health similar to the dire wolf.

The #1 thing that needs to be in TLC 3. At least make it as large and powerful as the mosa. Should have one of the highest attack dammages because scientists have proven that the megalodon has the most powerful bite of any living thing and is strong enough to crush a tractor trailer.

Good for clearing out rivers full of piranhas or sabretooth salmons especially on The Center

Really good to collect angler gel

Wild mantas can be fairly hard to hit with a megalodon.Just keep your shark still and the manta will often swim in front of its head.the rest is easy enough.with a high level megalodon even 120 mantas only take a few hits
