WARNING: The following contains spoilers for the story "Burn" from Wolverine: Black, White & Blood #3 by Donny Cates, Chris Bachalo & VC's Clayton Cowles, on sale now
Wolverine is one of Marvel's toughest fighters, but even he needs help on occasion. This includes against the Juggernaut, a villain tough enough to fight the X-men to a standstill on a semi-regular basis. However, Logan's latest brawl with the Juggernaut only required back-up from one person, who revealed the actual significance of the fight.
In Wolverine: Black, White & Blood #3, Wolverine and Cosmic Ghost Rider just quickly worked together to bring down the Juggernaut all on their own, cementing a specific moment in time from Cosmic Ghost Rider's perspective.
The Cosmic Ghost Rider is one of the most powerful versions of Frank Castle in any of Marvel's many possible future timelines. Originally introduced by Donny Cates and Geoff Shaw as the last survivor of a reality where Thanos eventually wiped out all life, the Cosmic Ghost Rider has been in the modern-day, traveling across creation and watching as the universe changes over the years. His latest stop is a small bar on Earth, where he encounters Wolverine. Logan recognizes Castle's scent and is surprised to find how different he's become. Castle reveals that while he's "Forrest Gump-ing" his way across reality, he's decided to check out one even that Logan told stories about for years after the fact, where Wolverine apparently took down Juggernaut all on his own in a barroom brawl.
After Juggernaut bursts into the bar, Frank is surprised to see how quickly the tide turns against Wolverine. Castle decides to intervene, reasoning that his arrival distracted Logan and messed with the events of the past. Luckily, the Cosmic Ghost Rider has the perfect weapon to bring down the Juggernaut, the Chains of Cyttorak, which are made from the corpse of his timeline's version of the god who gave Juggernaut his powers. This makes the chains a particularly potent weapon against the massive mystical brawler. Wolverine takes the chains himself and wraps them around the Juggernaut, with the Cosmic Ghost Rider using his Power Cosmic to drain Juggernaut of his abilities, limiting his strength and reducing his healing. With Cosmic Ghost Rider's help, Wolverine is able to defeat Juggernaut relatively quickly.
Leaving the Juggernaut for the authorities, Frank and Logan share a drink afterward, with Wolverine agreeing to tell the present-day Frank Castle this story, leaving out Cosmic Ghost Rider's involvement and setting up the possible time-loop to close itself.
However, the fact that this fight stood out enough to Wolverine to tell Punisher in the first place cements how important it really was. With Cosmic Ghost Rider's help, Wolverine was able to stop the Juggernaut in record time, without any further assistance. Considering that it often takes entire teams of mutant heroes working in concert to achieve the same effect, it's especially impressive to watch how just the two of them could stop one of Marvel's toughest brawlers who is famously "unstoppable."
Considering just how powerful the Cosmic Ghost Rider is, the fact that the Juggernaut was able to stand up to him at all is pretty good on Cain Marko's part as well. But Logan's quick thinking often gives him an edge over his ostensibly more dangerous enemies. This is ultimately what makes the battle a victory more for Wolverine than the Cosmic Ghost Rider: it's Logan's brutal side that finally ends the fight and sends Cain Marko on his way.
It's a historic moment for Wolverine, according to the Cosmic Ghost Rider, and a sweet one between the two brutal heroes, albeit one that suggests the possible apocalyptic events of "Thanos Wins" could still be the final destination of the current version of the Marvel Universe.
