I wish the item system from the handheld Pokemon games had been implemented in Pokemon Go. I evolved myself a Marowak this morning, and my inability to give him a Thick Club to hold is causing considerable mental distress. Because Thick Club Marowak is awesome.
For
@Squidleybits, in the handheld Pokemon games (ie, Pokemon X/Y, Black and White, Omega Ruby and Alpha Sapphire etc), individual pokemon can hold items, which have various effects. Some of them are universal and work for every pokemon, eg, a Lum Berry held by any pokemon would instantly cure its status effect if it gets burned or paralyzed or poisoned in battle. Some other items only work for a subset of pokemon, or sometimes only for one of them. For example, the item Eviolite would boost the defensive stats of a pokemon if it's not fully evolved, the Soul Dew boosts the Special Attack and Special Defense of Latios and Latias, and Arceus has a collection of seventeen plates that changes its typing depending on which plate is being held.
For Marowak and Cubone, there's an item called the Thick Club. When equipped by other pokemon, the Thick Club does nothing. However, when Marowak or Cubone hold it, their Attack stat is doubled. This means that a Marowak with a Thick Club can hit
REALLY hard in the handheld games. Admittedly, Marowak does have other problems, such as being quite slow, having relatively low defensive stats, and having limited options in its movepool. But when Marowak manages to land a hit on you, you'll definitely feel it. And I kinda miss being able to do that in Pokemon Go.
