Need Some Info On A Blitzwing KO I Found (maybe an Overcharge?)

Hello forum members! I've been lurking for awhile now and decided to dip my toes into the waters as I came across a knock off I have been unable to pinpoint. It appears to be a Blitzwing. I've also seen it names as an Overcharge. The thing that is odd is the vintage looking packaging. Any more insight into this fella would be much appreciated. Thanks
