its main attack is charging at you at a high speed, dealing more damage in low rank with g-rank armour than alatreon in high rank p3rd in a low rank rathian set.
it can also roar, and if you're standing too close, it will deal considerable damage.
it can also launch 3 rocks at you, and if you are in a snowy biome, they will deal iceblight, and if you're in a volcanic area, the rocks will inflict fireblight.
it can also launch itself at you in a pouncing manner.
he will also do either 1, or 2 bite attacks wich bring him forward a little.
its also possible for him to spin in a circle.
when returning in p3rd, he can combo a charge and a spin.
in mh4 he can turn around and charge immidiatly.
in 4u we got the apex tigrex, which can perform the brute tigrex roar, wich whom we will talk about in a bit.
and in Worldborne, after doing his triple charge, we will do a quick spin.
+ small lore, before gen 5, tigrex would stand on only his hind legs. but now he would be on all 4rs all the time.
and he will now sometimes slam his arm into the ground, and drag it through the ground later.
but sadly, he instantly loses this attack in rise.
in this game, there isnt even a sign of another type of tigrex.
but, if you are behing him, he will perform a tail swipe, catching you ofguard.
whilst the tigrex is mainly focussed on charging, the brute tigrx is mainly about the roar attacks.
brute will perform a charge whilst upright, before unleashing a supercharged roar.
and sometimes he will perform a second roar after the first one to catch you ofguard if you just dodged the first one.
brute also has a turning attack, but instead of charging, he will throw rocks at you.
he will now perform his superroar without the charge.
brute also got the normal tigrex's changes, but he will now also be able to do small damaging roars.
he can also combo these small roars a few times.
he can also do an alterred version of the tigrex groundslam, by punching the ground before dragging his wing acros.
he will also be able to use a gaint roar laser.
4 also added the molten tigrex, wich is a much bigger and more red version with blastblight.
molten first uses moves of normal tigrex, where he is slower then usual.
he can also do the spin, but now with explosions and blastblight.
later he will also start using brute's moveset.
and the charging will now also include explosions.
in the second-rage mode, ererything molten does will cause explosions.
and the last of them, a deviant from Mh Generations-Ultimate: THE GRIMCLAW TIGREX.
the grimclaw Tigrex is a much more blue colour with bigger claws, wich makes his claw attacks more dangerous.
instead of 3 induvidual rocks, Grimclaw will throw 1 big boulder, wich can explode into more pieces.
Grimclaw will also slam his claws into the ground to cause steam-explosions.
he's able to perform Brute's charge and roars + molten's fake-out.
and sometimes when charging, Grimclaw will put his claws into the ground to cause an explosion.
later he also gains the ability to create explosions wich go in a chained line.
