Pseudo-MOCs are what I call models made my fans, but still aren't traditional MOCs. In general, they're:
a) characters with visual representations but not official sets (the MNOG and MNOG II characters are the only BIONICLE ones I can think of), or
b) recolored versions of things like Fikou and Rahkshi.
Do you have any pseudo-MOCs? I have one. He's an Onu-Matoran from the Bohrok Online Animations. Black Pakari, black torso and arms, dark gray feet. He pilots a Boxor at the Battle of Le-Koro.
