As mentioned, Bills is the name used in Latin America. From what I can remember, it's a mistranslation that stuck. It was used widely back in 2012 and 2013 when we first learned about Beerus, and there was a lot of debate about whether his translated name was 'Bills' or 'Beerus' because the Japanese language lacks the 'L' sound. We only had 'Whis' (i.e. Whiskey) to presume that it was Beerus (i.e. Beer), but it wasn't uncommon to see people defend 'Bills'. And note, this was in the English-speaking world as well as Latin America. We eventually came to adopt 'Beerus' almost totally once Resurrection F came around (there are STILL a few stubborn holdouts somehow), but in Latin America, they used 'Bills' and never changed from it. I wouldn't be surprised if using 'Beerus' there is considered weeaboo shit the same way as using 'Tenshinhan' or 'Bejita' is in the USA or UK.
