Summary
Warning! Contains Spoilers For Black Widow: Venomous #1!Early appearances of theVenomsymbiote established its weaknesses to sonic frequencies and intense heat, yet over the years,Marvel’s most dangerous alienshave grown out of most of their weaknesses – until now, as a new addition to symbiote lore provides their equivalent to Superman’s Kryptonite.
Black Venom: Venomous#1 – written by Erica Schultz, with art by Luciano Vecchio –makes this major change to Marvel canon, when Black Widow infiltrates Alchemax to steala chemical capable of forcing a symbiote to leave its host, causing intense pain to the symbiote in the process.

Sliver,Black Widow’s symbiote, admits that the chemical hurts the symbiote and can easily even kill them. The fear of this new weakness is so great that Sliver even abandons Black Widow in the middle of their mission just to avoid the possibility of this new chemical being used on them.

While flame and sonic weapons were the standard, these work against most symbiotes, it doesn’t work on all of them…Because of this, people need new ways to take symbiotes down, and it seems Alchemax has stepped up to provide the answer.
Back when symbiotes were a rare occasion, the general population of Earth didn’t really need to worry about them too much. The only major symbiotes on Earth were Venom and Carnage, and places like Ravencroft used specialized tools to contain them. After the events ofKing in Black,the presence of symbiotes became far more common on Earth, with some symbiotes trying to simply blend into human society. This forced the US Government to come up withways to defeat the symbiotes if they ever became a threat.

While flame and sonic weapons were the standard, these work against most symbiotes,it doesn’t work on all of them. Carnage has famously outgrown both of these weaknesses. Because of this, people need new ways to take symbiotes down, and it seems Alchemax has stepped up to provide the answer. Readers were able to see a taste of this earlier inVenom#27. In this issue, a group of soldiers uses a chemical known as K34, which is so painful that Toxic explains it feels like being burned from the inside out.
It is unclear if what Black Widow retrieves from Alchemax is the same as K34, but Black Widow suspects its similar, and the vial is labeled KX.

It is unclear if what Black Widow retrieves from Alchemax is the same as K34, but Black Widow suspects its similar, and the vial is labeled KX. Having a chemical that immediately forces a symbiote to break its bond with a host is remarkably dangerous. It allows the capture of the host with the utmost ease, andit might just be the key to Marvel’s upcomingVenom Warevent.While Dylan Brock, Peter Parker, and Eddie Brock are all fighting over the Venom symbiote, only Black Widow will have the new weakness that could bring downVenom, no matter who ends up with the symbiote.
Venom
Venom is a symbiotic alien entity bonded with various human hosts, notably Eddie Brock and later Flash Thompson. It grants superhuman strength, agility, and a shape-shifting black costume. Initially a Spider-Man villain due to its origins, Venom evolved into an antihero, battling both villains and his own dark impulses. The character embodies themes of duality and redemption within the Marvel Universe.
