Vile thieving bird
Repost because the original post got taken down.
I have a suspicion that the VTB's spawn won't just be sunny's shadow,it will be his first true/complete shadow.
When Sunny shifted his gaze and looked into the soul of the peculiar youth, all he saw was a boundless sea of darkness. It was not the vile darkness of the Corruption, though... it was the familiar, tranquil depth of a shadow. And in that darkness, four Shadow Cores were hidden like tenebrous suns.
They were different from the shattered dark embers that burned within Sunny's Shadows, though — instead, they were very much like his own, resembling flawlessly round spheres.
And just like his own, these Shadow Cores were Supreme.
This description of the spawn's soul and the clear distinction between its soul and the soul of his existing shadows.
Sunny will be able to rip out his own shadow cores and bestow them upon his shadows to make them true shadow creatures/shadow spawn similar to him.
As for vtb spawn i dont think sunny will kill him to recieve his last shadow, rather he would subjugate the spawn using his authority over shadow and shadow creatures.
The title of ch 2950 lord of shadows also makes me believe that this might happen. After all wasnt the spwan a shade when the bird stole him from sunny.
Or he might turn the spawn into a true shadow creature after killing it then giving it’s shadow four of his own shadow cores thus creating his first true shadow and binding it to him as well.
Sunny will learn how to create true shadows from his shadows by following VTB's example. This also means theres a way for him to turn his shades into true shadow creatures as well since the VTB turned a shade into a true shadow creature.
