Greg is an ordinary male teenager going through everything ordinary male teenagers go through.. But Greg is somewhat non-ordinary most times. He is usually alone, he has no friends, he's being bullied occasion and is neglected by his parents who rarely notice him because he is the middle child.
Due to this ignorance Greg often lives in his own little world, he's imaginary little world, where everything is the way he wants it to be.
No bullies
No school and certainly
Nobody telling him what to do.
Greg spends most of his time in this little world of his alone. Imagining and living out his supposed best life.Today he could be the hulk, Tommorow he could be Captain America, The next day iron man or Thor. The point is he could imagine anything and live it out in his mind.
