Amarant is after Zidane because it's Zidane's fault that he got fired, and forced him to become a criminal. When he finally fights Zidane, he loses and decides to join up with him and his friends to find out what makes them so powerful. He hates Eiko and often calls her a brat (can't say I blame him, though), and has a really negative attitude towards life, often wanting to do things on his own instead of asking for help.
