If you wonder why it's Be not Ve
It's the same case as Street Fighter's Vega. It written in Japanese as ベガ (Bega)
so? Guilty Gear's Venom still uses -ve (ヴェノム). Vexan could still use a v.
also, there's an x in there. unless i'm missing something with where the name comes from, the x should be pronounced like an x. also also, is the lengthened -sa necessary? given there's no extra emphasis on the first syllable, there would already be implied emphasis on the second syllable. you would lengthen the -sa if it were to be romanized like -sar.
so the possibilities i have are:
- ベクサン (bekusan)
- ヴェクサン (vekusan)
- ビクサン (bikusan)
- ヴィクサン (vikusan)
