It’s not an infinity stone

Mixmellow:this is what the squid sisters are defending quant, if team annihilation takes it, I don't know what happens next.
Blocky:memes are doomed if they have that shard

“Well, what does it do? Also, don’t shorten my name like that ever again. I hate it when people do that.”

Mixmellow:sorry Quantum. I don't know what does these shards do, but I don't want to.

*Quantum touches the shard and it explodes with light*

“WOAH, WHAT THE HELL?”

“QUANTUM WHAT DID YOU DO?! I CAN’T SEE!”

“I HAVE NO IDEA!!”

Mixmellow:this is so bad! AAAAAAH!! WHATS HAPPENING?!
Marie:it's the shard's power! It'll go back inside the shard in 3,2,1.
*the light goes back into the shard*
Mixmellow:let's just all agree to never touch that again.

“Man, a Necrozma would love that. It’s a nice light source for them to feed off of.”

“What do you mean?”

“Most Necrozma need light to reach their most powerful forms.”

Mixmellow:so it's like moths?

“I guess except they actually convert the light into energy like a plant does, but sometimes they deplete the source in the process.”

“That’s interesting, I have yet to see a Necrozma.”
