It's SkillGreymon. Get it? Because... because that one evolution is... Never mind.
Anyway, when I was designing BoostKabuterimon, I added in a few small details that would allow it to combine with MailBirdramon. It feels hodgepodge, but that's kind of the point. As for strength, this is more of a DeckerGreymon than WarGreymon, ShineGreymon, or ZekeGreymon, so Ultimate+ rather than Mega.
On recommendation, I also did one with a lighter blue on the solar panels? I might use it in the future, as I've just been using Greymon's blue up to this point.
