Suggested by Sonic Genesect is a really powerful fighter with super speed and a lot of good energy attacks. I definitely would expect him to be taking the win over most other robotic fighters but Dromus did end up being one of the more powerful Tenkai Knights by the end. His dark abilities were formidable and so I see this being a pretty good battle. Ultimately I would give Genesect the slight edge thanks to the speed but it will be a hard fought battle that could have gone either way. Genesect just wins more often than not. Genesect wins.
