Great!
Three things really stand out in this series.
The first one is the voice acting. Absolutely fantastic, all the voices fit in perfectly with their characters. Expecially, of course, the Mastermind
The second thing was the art style. The all red and black really stands out and it matches the mood of the drawing style too. The front view of the Mastermind in particular is just perfectly fitting.
The third thing that really, really stood out to me was the timing. All of the pauses and cut-offs were placed perfectly. The humor was alright - it wasn't the best I've ever seen - but the timing complements it so well that it matches anything with better humor, and your art style just makes it awesome.
Again, really nice job, I look forward to the next one, if there will be one.
