Sorry, If I sound so rude, I wanted to ask you way before that and I'm asking you now : If you dislike FFXIII, FFXIII -2 and Lightning so much, then what are you doing on this board ?
Kupo was Terra's personal pet Moogle. However, one day, Toriyama kidnapped him, made him fat, made him overdose on helium to raise his voice, and named him Mog so that XIII-2 could have a moogle. Poor thing has never recovered his self-esteem, so he must thrive on hate to survive his pitiful existence. The fact that Lightning saved him, took him in when he was down, and took care of him has been erased from his memory due to the hatred he feels for Toriyama and in turn now feels hatred for Lightning. He now wanders around the forums, lost in hate, anguish, and his desperately tries to regain his lost self-esteem. Tis' truly a sad story.
