You know how it goes, guy dies meets a R.O.B and gets wishes and goes to teen wolf verse. He won't be a psychopath who doesn't care about lives of people and kills at the slightest inconvenience, but he also wont be a white knight. it will depend on the situation. 
 I struggled to decide if the M.C. should be a werelion or weretiger, but eventually decided on tiger because i have never seen a tiger fanfic and tigers are supposed to be more agile and stronger than lions in a one on one fight(at least according to google). 
Since tigers are solitary creatures there will be no harem.
i obviously dont own teen wolf and i also dont own the art of the cover
finally, english is not my first language so i hope you understand if i make some minor mistakes, even though I'll try not to.
