This results in the letter ヴ which is used to express sounds such as ヴァ, ヴィ, ヴェ, and ヴォ (pronounced va-, vi-, ve-, and vo- respectively). This has been a relatively recent addition, since 1954 according to what I googled, as more non-Japanese words have been integrated into the vocab pool so to speak.

Yes, I know this. The fact remains that the average Japanese speaker cannon form the sound of a "v," in the same way the average English speaker can't pronounce ㇻ, リ, ル, etc.

Gavv is not a word in any language that I can find, so it's not a transliteration or even a pun on a foreign word that sounds similar. It's a stylistic twist on the word/onomatopoeia "gabu," which refers to chewing, for a Kamen Rider based on snack foods. The meaning in is clear.
