For Some Explanation, in an RP, I asked How Big is The Griseous Orb? And one of my friends said "I always envisioned it to be the size of a Basketball."  But, After some Looking online for pics of the Timespace Orbs, I found these pics of the Lustrous Orb, from Losing It's Lustrous From the Anime.

But, After some more searching, I saw that on Bulbapedia, The Lustrous and Adamant Orb had appeared in "Unlocking the red Chain Of Events!" So after skimming through The Episode, I found the Orbs, and Here they are, with the title of the episode

So.... While i can't Say for certain how Big they are Compared to something in the real world, I This is showing how big they are. And if The Griseous Orb (Which HASN'T appeared in the Anime) is as big as the Other TimeSpace Orbs, That's How Big it would be



(Now i wasted 10 mins writing this. I'm gonna go back to RPing... Bye, Y'all! :D)
