either from monoblos quests (there is a chance in rewards or by making a monoblos get stuck in the wall, it drops a shiny that can be a heart), or from daimyo hermitaurs (by breaking its shell)
kill a white monoblos -_-
A Monoblos is a one horned wyvern in Monster Hunter. He has been brought up in several different games.
First you need the kikumonji sword.
I think you need to do Monoblos and Gravios trainings or F&H Treasure Hunting and get 2000 or more points, you should get them in Rewards
if you wanna know what element a monster is weak, kill one with raw damage (no element weapon), after you finish the mission, go to the weapon/armor dealer and look for the armor it produces, check the elements it has, the one that is negative or has the least amount of resistance is also the monster's weakness. for the subspecies of monoblos and diablos, ice is their weakness. If you want to know the spot where you can deal the most damage it is the tail.
monoblos, two velocidrome, trapped by yian kut ku, the ioprey leader,basarios, commander in the flames, a band of cenautaurs, more coal please, and hermitaur buffet

that would be Monster Hunter Freedom Unite on PSP and Monster Hunter Tri on Wii.
No one in the world can sensibly be a monster hunter as monsters aren't real. However, there is a video game called 'Monster Hunter' and it is popular and one can become a monster hunter through there.
You can get that and more on the monster hunter wiki
I will answer any monster hunter questions you have :)
There is no way to get invincibility in Monster Hunter Freedom.
