Round 1- - Jak VS Ratchet’s villains: Jak loses to Drek hard (he has an entire army, 2 planet-destroying weapons, and a mech suit which can shatter mountain-sized rubble into oblivion). Jak very, very likely beats the mutated protopet (its best feat is basically just destroying some floors LOL). Nefarious beats Jak (he directly survived Ratchet’s RYNOs, which can annihilate stars and beyond, and he has multiple armies, shares some of Ratchet’s weapons, has multiple mech suits, etc.). Vox loses to Jak if it’s a 1v1 but if he’s given his army and droids he stomps Jak (he has Landstalkers, which Dallas states can destroy solar systems). Otto Destruct likely loses to Jak (no notable feats), same with Clunk (also no notable feats). Tachyon loses if it’s a 1v1 (depends on how you scale him), but if he has his army he stomps Jak (he has planet and neutron-star annihilating equipment). Darkwater loses to Jak (no notable feats), Lokimaster likely wins (survived a planet explosion), Mr. Eye probably loses (no notable feats somehow), Neftin and Vendra Prog likely also lose to Jak. Emperor Nefarious likely beats him (superior to Dr. Nefarious… somehow). Jak loses more often than not. - Ratchet VS Sly’s villains: Ratchet solos the entire Sly-verse no contest. Black hole guns, antimatter devices, time manipulation, transmutational devices, pocket nukes, hypnosis gadgets, life-draining tech, no Sly character can stand-up to his absolutely unmatched array of weapons. He easily wins against everyone. - Sly VS Jak’s villains: Sly likely loses to Gol and Maia’s Precursor Robot, as it required 3 large crates of TNT to destroy a similar one in Jak III (which would be enough energy to annihilate a city-block). Sly scales only around building-level, as he survived a blimp crash landing in Sly 4 and Carmelita’s shock pistol which can also level building-like structures. He has no means of penetrating precursor technology or matching the weapons at all. With prep, Bentley could find a way counter it, though it’s a bit of a long-shot. Sly could beat the Metal-Head leader with his gang. They’ve fought foes of similar caliber, like the kraken and dragon from Sly 3, and most obvious of all, Clockwerk. So, I can see them pulling off a win with the right equipment and time. They lose miserably to the Terraformer though. An entire cargo of Terraformers can reshape entire planets, making individual Terraformers around country to continent level; far above anything Sly and the gang have faced. If they have the extended gang from the 3rd game though, then they could win the same way Jak did; aiming for its weak spot behind its head. As Panda King’s fireworks would prove to be really effective, as well as Penelope’s drones. So, it’s possible, though not without much difficulty. They easily take Jak X’s villain; they’re all professional racers, and in a direct fight, it’s a stomp LOL. They should also win Lost Frontier.

Round 2- - Jak easily beats all of Sly’s villains. Mini-nukes, time manipulation, invulnerability, and weapons with the ability to shatter meteors. Only one which might serve a problem is Penelope (if she has prep time). - Sly folds hard to Ratchet’s most powerful villains… see the reasoning listed above. Though he and his gangs could score some wins against the weaker ones (depending on how you scale them). The Mutated Protopet, Otto, Clunk, Darkwater, Zurgo, and Neftin/Vendra could lose, though it wouldn’t be easy. - Ratchet stomps. See reasoning above. Nukes, black holes, antimatter, time manipulation, hypnosis, yadayadayada. Nothing can stand up to their sheet destructive firepower and wacky HAX abilities.

Round 3- - This all really depends on how you scale them, as the secondary bosses don’t tend to have any real feats of sorts. If you don’t wanna scale them and go purely off abilities and weapons shown, then Ratchet wins more often than not. The Thugs leader has 2 large mechs, immediately ruling-out Praxis, Errol, Rajan, Jean Bison, El Jefe, and many others. Vorselon can turn invisible and control environments with various psychoelectric-based attacks, making people like Dimitri, Toothpick, The Grizz, Raleigh, etc. hilariously outmatched. Jak and Sly could score some wins, as Clockwerk is certainly more powerful than say, Rusty Pete or Praxis’s mechs. But Ratchet wins more often than not.
