The number 1 stuff aside, I wonder if this could be a Gingaman-ish show with a pinch of Norse mythology influences. As for the "number 1" aspect of the title, I just realized the 1 could be further proof that red ranger being a wolf is likely more than ever, or at the least, a canine of some sort.
This is because "ワン (pronounced wan)" is also the onomatopoeia for barking noises that canines make in the Japanese language. A good example of this wordplay can be spotted in Tatsunoko's anime Yatterman, where their first mecha is the Yatter Wan, a canine-like robot whose latter part of the name is a wordplay on the number 1 and the barking noise of a canine.
