If you had a mega evolution

[Sylphiel]

Sylphinite I guess.

Or I personally like the spelling of Sylphenite even if it doesn't follow the letters of my username exactly but whatever.

 

[G0!d]

Goldite. Or Dolgite.

My mega evolution is me doing actual work rather than posting on pokeforums {XD}

 

[Evening]

Sandwichite.

Perfection.

 

[Spiff]

Alcohol

 

[Hikamaru]

Nicholite

It does give off a "mineral-ish" feel.

 

[Limey-chan]

Limestone! AHAHAHAHAHAHA

Ahahahaha

hahah

ha..

 

[Lucid]

Alcohol

Delete this.

 

[HollyYoshi]

Mine? Hollynite.

 

[Universe]

i'maiiite

 

[Livewire]

Livewireite

Or, realistically speaking, beer and hot blondes.

 

[Kikaito plush]

Talite ?

yeah that is just terrible

 

[Melody]

Melonite

Also, I'd likely be able to Mega Evolve without a Mega Stone Activation, just with this stone in certain conditions, much like the ones that govern Digievolution where it happens only when someone I care about is in danger. ;)

 

[Pave Low]

lucaslucarionite

 

[Synerjee]

Either Synerjite or Amandite. Idk.

 

[ElCabron]

CABRONITE!!!

Nah. Lucasite or Tiradite! Lucasite is way too gorgeous though!
Silvite if I was a fairy-bulous type!

 

[Wicked3DS]

Wickite, Wickedite, Alexite, 3DSite?

 

[Klippy]

Klippite. :D

 

[Legobricks]

Forgetful Stone

I genuinely think that's a nice name for an item in an RPG. Sounds like a humble heriloom artifact that one could use for some great purpose at the cost of their memory.
