One angry deer was not here for the petting zoo vibes — and proved it by going full UFC mode on a roadside stranger!

You gotta see this — a guy on a motorbike in Shanghai, China stopped to pet a deer, and the next thing you know, Bambi went full kung-fu, rearing up and drop-kicking him in the chest.

The man scrambled to block the hits, but the deer wasn’t done — stepping back just long enough to reload before unleashing another hail of hoof slaps.

It’s unclear if the rider walked away with any injuries — but thank goodness for that helmet, because without it, this deer duel could’ve really bucked him up.
