Chad Johnson -- the bad boy from JoJo's season of "The Bachelorette" -- is out for blood ... specifically from Colton Underwood or Nick Viall, but the violence is for a good cause!!!
We got Chad out Tuesday at Blvd Boxing Gym in the San Fernando Valley, and asked about his boxing match coming up April 22. The event's being dubbed "Battle of the Bachelors" ... and there's only one problem.
Chad doesn't have an opponent, at least not yet. Of course, he has a wish list, and he didn't hesitate to explain why he's dreaming about doing some damage to Nick's "stupid face.
