Mini Beat Power Rockers is a children’s animated series that was aired on Discovery Kids. It has aired in 2 main language, those being Spanish and Brazilian Portuguese. But there’s a dub that’s lost and might stay lost. That being the English Dub. The English dub is aired on Discovery Kids (in Australia, there’s a feed there just like the South America ones). And it’s also watchable by using the SAP (Secondary Audio). A few episodes were uploaded to YouTube in English but they weren’t in good quality. So was the English opening. It’s possible the whole show was English dubbed but it just isn’t documented. Until we find a good quality English dub of this show we just have to wait.
Update 12-08-22: A archive.org page by the name of MBPR Archive has recorded some english dubbings of the show from Discovery Kids.

Update 03-12-23: I, have the Discovery Kids stream that’s in English. And im recording them right now, they should go to YouTube soon, I did this because I wanted to see more of this dub and Underdogs United, as I uploaded them already on my channel, not all, wish I had discovery+ in brazil
Update: 08-06-23: I have 2 things to say, even thought it is airing on Cartoon Network Australia, no one is probably recording them, also, there is some on Archive who is archiving the series from recording on Discovery kids, 47 episodes are uploaded as of now. https://archive.org/details/mpbr-english
Update: 03-23-24: As of February 2024, The dub is available to stream on Max. https://play.max.com/show/e97ca7cd-5899-4d77-8892-f04de23574da
