Yeah, I've used them in RPS before. This is just an idea of what they look like. By the way, they're wearing their usual clothes. I don't think that their clothes are gonna be it's final design. Except for Lloyrumi. I quite like her outfit. Now, let's see...facts?

Fact #1:
Liam is the next green ninja, Lili is the next princess of Ninjago, Lloyrumi is the quiet one, however she doesn't have any powers and JadeEnergy is not technically blood related to the three others(she comes from another dimension). In her dimension, she's both the princess of Ninjago and the green ninja. But she changed the term to: "Mint Ninja"

Fact #2:
Lili's dress used to be pink with peach bows around it. But I felt like that wasn't really much "jade princess" at all. So when I added green to her dress, it didn't really suit her light blonde hair much so I changed it to light blonde.

Fact #3:
Lloyrumi used to have a bun as her hairstyle but I thought that it wasn't too creative as a hairstyle so I did Harumi's quiet one hairstyle but shorter and added a bun. As you may have noticed, I added the black chopsticks. Just like the others Rumi wore in S8.

Fact #4:
Liam's real outfit is a green ninja suit(no surprise) but he enjoys wearing green hoodies like his father. As you may have noticed, there's the word: Midori on his right sleeve. Well if you're a Yandere sim fan, you would have known that Midori means: "green"

Fact #4:
JadeEnergy wasn't supposed to be an OC. she was just meant to be a nickname given to Lloyrumi along with: "Llorumi and GreenRoyalty" (yes, the nicknames are jokes on Lloyd and Harumi's other ship names). But then, I found the name so fascinating, it isn't really a name I know. (Who would name their kid JadeEnergy?) That I made her an official OC!
Her character design is not really what I was looking for so I might redesign her honestly. I don't even know why I made her have light green dyed tips. Now that I observe her more, it looks weird on her...
