In WoWP you may choose a side to be on when the plot thickens or special events take place:
1)Team Dark: Run by Chester Thomas, a cruel poacher who literally hurts pokemon so bad most become handicapped for life. His team think that humans are the ultimate are Pokemon are just tools. They capture pokemon with their own pokemon and damage them or sell them on the black market. If they become weak they are killed by Team Dark's Pokemon.
2)Team Light: The leader is Sam. Him and his team respect Pokemon and put their full trust in them. They are committed to stop Chester and his team before things get out of hand. They just need to be fast enough to know what Team Dark's next moves are before they act on them. All of Team Light's pokemon are bonded deeply to their trainers and are trained to find Team Dark's Pokemon.
3)Neutral: If you choose neutral you do not know or don't care of the war. If you are a pokemon you are lucky enought to not get caught and be on your merry way. If you are human you are oblivious to the threats and instead work on collecting badges and capturing pokemon.
