let me guess, we will sell his stuff in that auction later, get rich, attract the attention of power full people, show off his absolute power just to realize later that it is not enough and they are more powerful people out there. from there he will somehow get in contact with a rich lady X help friend Y get powerful and somehow attract the attention of a secret organization. and did I mention how he will get a useless beast and evolve him into omega lvl Z? well you are welcome. this is only a guess though, not a chance of it happening right?
