Sonicore was officially cancelled for a total of two days before being revitalized. This was due to the mediocre reception of the first season of MineZ (portraits, errors, etc). However, the series was remade and had much better reception.
Sonicore has had the first appearence of:
Jeff and Moose in MineZ #1
Kool in Block Party #1
Willow and Psalm in Minecraft #1
The series style of portraits is inspired by Pokemon Trainer sprites, and may be used in other hardcores.
