Make an Item!

[Mockery for One]

Now here's one.

The No-Type Rod, a double-pronged stick, only lets the other guy use whatever Normal type moves he/she may have on him/her. It's basically a shout-out to the evil Cutie Mark-thieving stick from MLP's season 5 opening 2-parter.

Sharp Sword

Slashing or biting moves have twice the base power for all pokemon in battle while the holder is in battle.

[Dorchadas]

Infant Stone

Stops a foe's Mega Evolution and reverts them to their earliest evolution.

[E.C.A.M.B.S.]

Leash

The holding Pokemon is switched out after it attacks.

[SaRo|Rapidash]

Golden Leek

If held by Farfetch'd, increases critical hit chance is increased to 50%.

Something to make him more useful? But not really. 

The plain old stick already does this, raises his crit rate by 2 stages to 3, which as of XY is a 50% chance to crit (or 100% if a high crit rate move), and unfortunately farfetch'd is still garbage xD

[Captain Jigglypuff]

Infant Stone

Stops a foe's Mega Evolution and reverts them to their earliest evolution.

Sounds cool and all but how would it work? Would you have to Fling it at the opponent or use Trick or Switcheroo?

Taylor Swift, Katy Perry and Kayne West dolls that sing:

The wild or opponent's pokemon will flee in terror.

You only have to be one of the active pokémon when a mega evolution takes place. However, to make it not too OP, you can't switch in the pokémon holding the stone after the evolution and have its effect take place, nor can it be used if the pokémon is inactive/in your party. Also, forgot to mention it works on Primal evolution too.

Powershell

A sturdy shell that heightens def and sp def but lowers speed. Only works on turtle Pokemon
(also on side note, my Fakemon Voltortus evolves into Amportus or Surgortus based on its stats while holding Powershell on level-up)

This one is the Star Rod and is based off the Kirby weapon of the same name. It allows Yoshi to Primal Reverse, and is found in the VEEEEEERY center of the Prism Tower/Lumiose Gym during a REALLY long Fake Cheat involving the Odd Egg (which Yoshi hatches from), a decision question about whether or not you want to go with him, the Internet as an alternate dimension (you must have Nintendo Network and a stable Internet connection, as it asks you if you want to go online), Espurrs, the Psychic Amulet (how Yoshi gets his OP powers), and MLP-related things.

Shadow Cloak

It increases the evasion of dark and ghost pokemon when worn and booses dark and ghost attacks.

It's the Staff of Sameness, and the item I mentioned is the Staff of Normality, and it makes the opponent and his/her move types Normal, and if the holder is Starlight Glimmer, she gets to be Normal Type too!

poisonous ivy

Poisons non grass types, heals grass types by 6% of the holder's hp

[in other words, same as leftovers, but for grass types only, other types just get poisoned]
