Morlun is Kane's father!

Ezekiel Simms is an A.I hologram generated by Morlun, he is addressing people in a conference call when he is shortened out by Morlun awakening. Morlon contacts Kaine and tells him to find Peter. Peter and MJ touch down in New York after a spot of web swinging, MJ proposes marriage to Peter after they kiss but Peter is hesitant, they're already married but he's afraid he might lose her again. MJ is annoyed and storms off, Peter is being observed by Kaine.

Kaine returns to his 'father' Morlun where he frees him from his cocoon of webbing. Vermin randomly appears but Morlon kills him and feasts on his energies. Morlun rambles on about spider-totems and Peter's importance.

Mary Jane returns to Peter, storming into his bedroom, ripping the bedsheets off of him and demanding answers. Peter admits he's fearful of the future, but MJ tells him they can make their way through it all. She proposes a second time and Peter says 'yes'.

Spidey battles Mark Raxton, aka the Molten Man, very strategic feat here. Peter and MJ arrange a dinner with their Aunts. Aunt Anna seems to have put on a few pounds. She still hates Peter just like in the cartoon. Peter says the marriage still feels 'brand new' to him (hur hur). Peter's looking into getting into teaching.

Suddenly, Kaine attacks. He and Peter clash outside, Peter holds his own against Kaine for a bit, but ultimately Kaine gets the upper hand and nearly defeats Peter, but is defeated when he senses just how strong Peter's love for MJ actually is. He flees, returning to Morlun, but Morlun turns on Kaine and destroys him, feeding off his energy also. Morlun then enters a lab containing cloning pods and begins growing another Kaine

so it looks like this is same Morlun that appeared in other universes in comics because he keeps refering to Peter as Spider-Totem

The writer has said Morlun isn't the same as the other one, and has a different origin

Morlun in the guise of Ezekiel presents Project Lokka to Wilson Fisk and guests. Fisk is now Mayor. Project Lokka, named after Molrun's homeland, is a solar power plant which Morlun intends to use to spread clean suffient power across the east coast. The plant will be launched in a matter of weeks.

Spider-Man learns from Kraven that Mariah Crawford, Calypso, is dead and that the serum Peter gave her to cure her mutation weakened her cells, she passed in Kraven's arms. Kraven then finds out from reading Crawford's notes that she was aware the serum was killing her, and that it was decaying the cells in his body too. He hastes the end by drinking the serum and sought out Morlun, whom he had heard was murdering innocents.

Kaine talks to Mary Jane (armed with a baseball bat) and reveals all of Morlun's cloning has opened his psyche more and more, allowing him to recall all his previous lives and to reach out to the minds and hearts of others, learning more about them. Mary Jane asks Kaine to confront Morlun and save Peter. They share a sweet moment together before Kaine returns to the lab.

Peter and Kraven battle some mutations at Morlun's lab. Peter prevents Kraven from taking any of their lives but Morlun arrives and kills Kraven's pet lion before draining Kraven of his life energy. Kaine arrives to stop him but Morlun kills him....or so he thinks, then Kraven springs back to life, mutating further and further...becoming what appears to be THE MAN THING (or at the very least, a Swamp Thing knock-off)
