And, Garcia's clearly dead serious ... warning 27-0 (25 KOs) Tank not to let his IG fame fool him, 'cause at the end of the day -- despite his 8+ million followers and funny clips -- he's still a 22-0 boxer.
"Just know that there's a lot more than meets the eye with me. Don't think I'm soft," Garcia said.
"You come find out and actually make that decision to fight me, you'll find out real soon there's nothing soft about me."
Of course, the 23-year-old lightweight has to get through Fortuna (37-3, 26 KOs) first -- that bout is set to go down on July 16th at the Crypto Arena in Los Angeles (it's airing on DAZN).
"He's an ex-world champion. He's a veteran," Garcia said about Fortuna.
"But, the fact that I'm coming into, I feel my prime and my best ability skillfully and mentally, I feel like this will be a short night for Javier Fortuna."
Garcia added one last thing, "I just know I'm gonna fight Tank after I beat Fortuna."
