Carrier has an alternate look called Paras that makes it look more like a parrot, if I remember correctly. I want to say it's a cosmetic otem applied to a normal Carrier, but I am not at home, so I can't double check.
Actually, Inaros' 4 is more than just an Armor boost. Once you've got it up, you can tap the button to sacrifice 25% of the Armor boost to CC an entire group of enemies, including ones that walk into it after the initial cast. In addition, you get Health Regen while standing near enemies affected by it, making it quite easy to restore your health so you can get that 25% Armor you gave up back.
