This is a minor issue, but Legendary Chill from Giants, Legendary Grim Creeper from Swap Force, and Enchanted Star Strike from Swap Force are all lightcore as well. I don't know if the omission was on purpose for horizontal space, but I think the lightcore status of these figures should be reflected to prevent possible confusion.

Additionally, Legendary Sun Runner shows up under Superchargers Characters instead of in Vehicles. The Superchargers Trophies are in both Superchargers and Item; I think they should just be in Items. The Fiery Forge magic item is in both Items and Adventure Packs; I think it should just be in Items. Also, I think most people consider the Volcanic Vault a magic item, not an adventure pack.

Finally, you included chase variants in the Imaginators list. Chase variants mean they aren't different in-game even though they're different IRL. Since they don't change in-game, their editor entries don't need to be separate.
As far as I could tell, you only added chase variants in Imaginators, but if I notice any others, I'll report them here.
Edit: I double checked the other games for chase variants, and Clear Thunderbolt from Trap Team is the only other one I saw.

Edit: In checking my collection, I discovered that chase variants do actually have different variant data from the figure the chase variant is based on, even though the chase variant doesn't actually appear different in-game.

Unrelated side note: Are you still working on the To-Do list?
