>>44460125They were meant to be akin to Team Skull, comic relief antagonist while the bigger bad lurked in the background.
The issue for me is that both times the series have done this have never topped the original Colosseum version of it. Skull/Yell are more "amusing" than Snagem was, but at the cost of plot relevancy and seeing the "twist" coming a mile away. The red herring is too obvious, whereas Colosseum didn't bother and still handled it in a more competent fashion.
