Obviously the issue here is that we had to wait on Scorpion Striker to release...
That likely impacted the overall votes as what is fresh/new tends to influence the average person...I am still not sure that the results would have been much different if they were both released at the same time. While I really like Chop Chop, I just feel like Chop Chop + Shroomboom will have a tough time with Zap + Hot Dog as those later characters tend to resonate better with most fans. That said, here are the results:
1. Scorpion Striker 88 Votes, 76%
2. Dragonfire Cannon 27 Votes, 23%
It was basically every 3-in-4 voting for Scorpion Striker.
Personally I would give it the edge as well since Zap and Hot Dog are just a better pairing.
