Omg pls spill about ur christofern I'm now curious as to what urs is like OvO
well let's start with his ref sheet. This is a bit old but i'll do, it's still his design, some is subject to change but not much, maybe just some colors.
and this is the actual one that has been posted
So how we got Christofern, was he was a baby(maybe like 1 or 2) that during the March of the oni, got lost and as a defense mechanism of the Oni species, he became a plant, aka the first thing he saw when he stared panicking. So after a while he (as a plant) was sold to vinny(this sounds so wrong please bear with me), and ended up with Garmadon. Now Chris can hear all that's happening around even though he's a plant, so this does me that well, he heard Lloyd yell at him/Garmadon in crystalized, this makes him somewhat scared of Lloyd when they first meet.
but he forgives Lloyd really quickly because he's well he's like 2-3 so since Lloyd's being nice to him now, obviously it's ok. Anyway, so they figure out Chris is an Oni when, after Crystalized, and the Ninja not being statues anymore (my re-write, which well that's a different post), Lloyd goes up to see the plant, cause he's feeling a bit better about it and his relationship with his dad, and well he's able to sense that Christ is not a plant... so after getting Garmadon and wu they are able to help Christ take a human-esk form, it's not a full oni form, cause Chris wanted to look like Garmadon's son, who is lloyd so he based it after lloyd to some extent.
They "find" Chris when the Other Ninja are off getting their powers back, so when they get home, lloyd has another siblings, they are all shocked.
The flower Chris wears is a Astragalus, which means "your presents softens my pain" Lloyd gave it to him as a kind of apology for yelling at him in crystallized.
I think that's all I have on him for the time being, so hope you enjoyed my info dump.
ps: he's also scared of brad for a bit since brad's a gardener and he does cut plants. Christ warms up to him after some time. The Darkley kids find this hilarious.
