WARNING: The following article contains major spoilers for "Rick Grimes 2000" from Skybound X #1-3, on sale now.
In The Walking Dead, Negan might just be the most despicable villain of the franchise. He commanded the Saviors to do heinous acts and is famous for smashing Glenn's head in with his barb-wired bat, Lucille, in comics and the TV show. While both the comics and the show would redeem him to some extent, that redemption just can't wash away his sins in full.
But in Skybound X #3, an alternate world's Negan is made into an even more powerful tyrant thanks to alien tech. Negan's upgrade is unleashed in "Rick Grimes 2000," when he smashes into the Sanctuary where Rick, Andrea and their allies are plotting their next move to repel the alien invasion. It's the last bastion of humanity where Michonne's being potentially revived after her beheading, and kids like Carl get to have some semblance of a childhood.
But to Negan, this is the ideal place where humanity can be cornered and murdered. Like the Governor, he's sided with the aliens, crashing in with his own hovercraft. As he breaches, his bat has been upgraded into a powerful weapon and split into two halves: Lu and Cille. Negan uses them to deflect bullets away, swatting them into the opposition like tennis balls. He even compares himself to Popeye, saying that the crowd's gunfire is just powering him up like spinach, proving he's just as talkative as his mainstream The Walking Dead counterpart.
What's interesting is the halves also seem to be sturdier than anything else, smashing Abraham's face in and damaging Maggie's hand. Negan can even use them to generate shockwaves, knocking Rick's team out.
It culminates in him combining the halves to form Lucille, which has an electric field around mimicking the barbed-wire. Even though he came in like a one-man wrecking ball, Negan is using it to summon his mysterious allies, and things doesn't look great for Rick's battered and bruised crew.
The fact the aliens were able to power him up also speaks volumes regarding their plan and their power, since Negan doesn't play well with others and definitely doesn't like being someone's servant.
With his lightsaber, Rick might be the only hope as Negan combines the two pieces of the bat, not unlike He-Man's Power Sword. With her considerable firepower, Andrea has shown she's got some tricks up her sleeves in terms of weaponry so she may be the trump card. Only time will tell whos steps up to face him, but what's certain is this Negan is the most dangerous and deadliest the resistance has ever encountered, and he's poised to wreak major havoc.
