Brother Nature Seen Confronting Attackers Before Beatdown in New Video

Brother Nature sure seemed ready to fight -- at least that's how the moments leading up to his dual-threat beatdown appear to have unfolded on surveillance footage.

TMZ got a hold of surveillance video taken at the Miami-based sandwich shop where BN was later pummeled twice over ... once in the parking lot, and again inside the restaurant. In this new footage, you can see Brother Nature initially confronting his two attackers.

As we reported ... Brother Nature was allegedly upset that he couldn't be served at his table, and tried griping about it to the shop's staff. We're told he then got in the face of one of his attackers -- who was supposedly filming him -- and you can see that interaction here.

Brother Nature is asked to leave by someone who works there, but not before some words are exchanged between him and these 2 guys who were also more than willing to brawl.

Fast-forward to the parking lot stomp-out ... which then spilled back into the eatery, where we're told BN stormed back in and allegedly socked somebody. It appears you can see that here in the surveillance video as well ... Brother Nature comes in and rushes the slimmer dude, seemingly trying to hit him, before his buddy scurries over and they team up.

The rest is pretty much history -- Brother Nature got walloped by the two dudes ... and by the time cops showed up, everybody had gone their separate ways.
