Despite the fact that Mr Immortal is completely unkillable, Thor would still have that one in the bag, since Mr Immortal has no other powers. Including regeneration! Keep that in mind. Thor could rip off Mr Immortal's arms and legs, cauterize the wounds so he doesn't bleed to death, and use his medical expertise to make sure he doesn't die from shock. Mr Immortal is then stuck. Fight over. In order to regenerate, Mr Immortal has to die. He then resurrects, with all damage completely healed. IF he doesn't die, the damage stays. But if hes disintegrated or something of that nature, he just comes right back. Thor isn't stupid. He'd figure it out after a couple "deaths" and just incapacitate Mr Immortal.
