There’s a barely measurable moment before Hem Dazon performs his patented pop-up move where we can see Arleil Schous, Brainiac and Bom Vimdin sitting at a table. Between Brainy and Bom is this guy. He was once commonly referred to as FuManchu, thanks to his prominent mustache. More recent information states that this character wore the same mask as Trinto Duaba, who was released in the Legacy Collection, but with the added mustache.
While, on his own, he’s pretty pointless, 2 of his 3 tablemates have been made already. The set can’t be completed without him. In theory Hasbro already has a headsculpt to work from, and the mustache could raise his appeal with hipsters.
