With the Charlo twins set to headline separate main events within the same unique pay-per-view doubleheader on Saturday from the Mohegan Sun Arena in Uncasville, Connecticut, there are no shortage of storylines surrounding the 30-year-old rising stars. 

Both Jermall Charlo (30-0, 22 KOs), the WBC middleweight champion, and brother Jermell Charlo (33-1, 17 KOs), who holds the WBC 154-pound title, enter what can be legitimately called the toughest challenges of their respective careers on Saturday. The six-fight event (Order on Showtime PPV, 7 p.m. ET) also features a four-pack of exciting matchups in the bantamweight and junior featherweight divisions. 

Let's take a closer look at what to watch for entering the Showtime Boxing PPV extravaganza featuring the Charlos this weekend.

1. PBC betting time is now on all things #LionsOnly

With an equal balance of speed and power to form a combined pro record of 63-1 with 39 KOs, the 30-year-old Charlo twins have both seemed one breakthrough victory away from cracking the sport's top 10 pound-for-pound list in recent years. Marketing wise, however, there has always been talk about the potential of their #LionsOnly brand becoming more, maybe to the level of being a household name across the sport (and beyond). Following a flurry of headlining roles over the past year on pay cable and in primetime on national television, PBC boss Al Haymon believes the Charlos' time is now to take that swing in this somewhat historic double PPV main event across two cards. There has never been a doubt that the fighting brothers, who are just as competitive seemingly with one another other even more so than their opponents, have the right kind of brash attitude to sell themselves and a firm understanding of how to grab an audience's attention. But for this PPV kickoff to truly have lasting power, both will need to win in very difficult matchups, respectively.

2. Jermall's island finds shipwrecked passenger

Among the most talented and well-rounded talents in the 160-pound division, Charlo simply hasn't had the opportunity to prove his skills translate the same against the elite members of the division. His prior junior middleweight title run brought him impressive wins over names like Cornelius Bundrage, Austin Trout and Julian Williams. His five fights at middleweight have largely seen him on the wrong side of boxing's political line, however, despite a respected decision win over former champion Matvey Korobov. With his goal remaining the same of an eventual showdown with Mexican icon Canelo Alvarez, Charlo finally gets the chance to prove his worth against as tough an out as the division can find in Derevyanchenko. For every bold word Charlo has ever proclaimed in the face of critics, this fight represents his ultimate shot at having the last word in regards to where he stands. 

3. Derevyanchenko hoping third time is the charm

A native of Ukraine with an extensive amateur background (who called the likes of future world champions Vasiliy Lomachenko, Oleksandr Usyk and Oleksandr Gvozdyk as teammates), it didn't take but 12 pro fights for Derevyanchenko to earn his first pro title shot. Despite two outstanding performances in title shots against Daniel Jacobs and Gennadiy Golovkin over the past two years, Derevyanchenko has nothing to show for it. While he deserved a mild level of contention for his split-decision loss to Jacobs, it was his absolute war with GGG -- who received the nod from all three judges -- that Derevyanchenko seemed to find the majority believing he deserved better. Not only did "The Technician" rise from the canvas against both to showcase his toughness, he stood up to the powerful Golovkin and became the aggressor as the fight wore on. At 34, there's never a guarantee how many future title shots will be available to any fighter, let alone one who faces the reality of a third defeat being his last. It's now or never for such a great fighter to realize his full potential. 

4. Control of loaded 154-pound division at stake

For all of the justified complaining by boxing fans of the sport's constant disorganization and political trickery, the junior middleweight division is an almost throwback example of how the sport used to be. Nearly everyone at 154 pounds who matters fights under the PBC banner, and just about all of them are willing to try and prove they are the division's best the old-fashioned way: doing so inside the ring. Charlo faces off with the upset-minded Jeison Rosario, owner of the WBA and IBF titles after shocking Julian Williams via TKO last year, to allow the winner a firm grasp on the division at large by owning three of four recognized belts (Patrick Teixeira holds the WBO strap). Considering how insanely competitive the biggest 154-pound fights have been over the last two years (including the likes of Jarrett Hurd, Erislandy Lara and Tony Harrison, to name a few), it will be nice -- for as long as it lasts -- to see a temporary king crowned. 

5. Loaded undercard puts spotlight on two divisions

The double Charlo PPV might be new school in its execution, but it carries with the classic charm of what used to be a standard throughout the sport: an undercard worth making an appointment to tune in early. In whatever the four support bouts under the two Charlo title clashes lack in mainstream appeal, they more than make up for that in terms of street cred from the hardcore fans. Competitively matched with each promising a certain level of two-way violence, the four world-class fights also offer the competitors a chance to steal the show at large. Will it be Mexican slugger Luis Nery (30-0, 24 KOs) in his vacant super bantamweight title bout against fellow unbeaten Aaron Alameda (25-0, 13 KOs)? Or how about WBA 122-pound titleholder Brandon Figueroa (22-0-1, 15 KOs)? Others are pointing to WBO bantamweight champion Jon Riel Casimero (29-4, 20 KOs) to carry on the Filipino fighting tradition of Manny Pacquiao. Either way, there are no shortage of explosive candidates.
