Oh, fire types.  How fascinating they are.  Ever wonder how they can shoot a flame out of their mouths without harming themselves?  Well, I know an answer.  Inside their bodies, there is a trace of a flammable gas, such as hydrogen, which they can use to blast fireballs out of their mouths.  Sound surprising?  It is actually possible.  On a Discovery Channel special on dragons, scientists figure that a dragon uses helium to use fire.  But, this fire has limits.  At a certain point, too much fire will make the user run out of the fuel, and in a Pokémon's case, this is measured in PP, or power points. 

 

Now water types.  Yes, it seems likely that animals can store water in their bodies, but can they really store that much?  This is why water types must go back into the water to refill.  But sometimes, the amount of water they can carry seems too much to be possible.  So how do they do it?  I have no clue, you tell me.  Seriously, please tell me. 

 

Psychic types.  How do they use their mind to move objects and manipulate the mind?  Who knows, but I have a theory.  Perhaps the Pokémon uses their mind to send out energy that can manipulate foes.  This can be lifting them off the ground, mind controlling, or doing that shrinking act that Sabrina does on the TV show.  So do you think it's possible? 

 

Oh electricity.  Put it into a Pokémon and you have an animal shocking you half to death.  There already are real animals that can release electricity.  The electric eel can already release voltage, and there are others.  So it is probably one of the most likely Pokémon abilities to be used in real life.
