Former pound-for-pound king Manny Pacquiao is already in beast mode early into his training camp, as the Pacman unleashed his trademark power punch at his sparring partner Lydell Rhodes, who reportedly had a bloody nose in his first encounter with the Filipino fighter.

The 35-year-old Pacquiao already hit the second week of preparation for his upcoming WBO Welterweight championship rematch with Timothy Bradley Jr. Motivated by his first loss to the American two years ago, Pacquiao is taking his training very seriously, whether its on the mitts or during sparring session.

On Monday, ABS-CBN news reported that Pacquiao hurt Rhodes in their first sparring session, busting his nose open after landing a powerful left straight to the face of the American boxer. Personal assistant and close friend Buboy Fernandez called the first day of sparring a success for Pacquiao, who was able to show that he hasn't lost his killer instinct in the ring.

Sparring Partner in Awe of Pacman

Rhodes, who previously worked with Floyd Mayweather Sr., is the first of several sparring partners head trainer Freddie Roach will be bringing in to toughen up Pacquiao. Former Jr. Welterweight champ Kendall Holt and lightweight title-holder Steve Forbes are also scheduled to take on Pacquiao, when he shifts his training to the Wild Card Gym in Los Angeles, Calif.

Rhodes said he was surprised by Pacquiao's lightning quick speed, saying he didn't expect to see Pacman in tip-top shape two weeks into his training.

"I was surprised and it was really good [the sparring session]," Rhodes said in an interview with GMA News via the Manila Times. "Manny is in better shape, moves faster and stronger than I thought he'd be. We're doing very well and we're making some adjustments. We have a game plan."

Going for the Kill

Roach said he was impressed by Pacquiao's conditioning and aggressiveness on the first day of full training.

"I like what I saw in our first day on the job," the 52-year-old Roach told philboxing.com via The Manila Times. "Our goal is to win by knockout and I think it is possible."

The Pacquiao vs. Bradley showdown will take place on April 12 at MGM Grand Garden in Las Vegas, Nev.
