@Kynos Kynos did not know it but, Venom was a believer, he served his vampire master with all his heart and soul. It was only Minnie that talked some sense in him and gave him a reason to live. Venom's original plan was to be captured on council island and then attempt to assassinate someone. Unfortunately the bomb also had a secondary trigger mechanism, in the case of death to eliminate Venom and everything he might carry.
Since Venom was an idiot with too much money to spare the cortex bomb was so advanced and well integrated to his brain that he actually managed to walk passed airport security with it. A fact that should Kynos survive may be very interesting to him. What Kynos missed in his perception check are the traces of recent head surgery a surgery that could as well pass for a data jack or smart-link surgery.
As Kynos breaks Venom's neck and Venom's head explodes in Kynos hands. Knocking Kynos back in surprise and sprays metal pieces all over the passenger area of the plane. Luckily Finestra did not want to witness the actual kill and waited in the cockpit behind a closed door until the deed was done.
Venom had a cortex bomb in his head that is mechanically like a fragmentation grenade. This means 18P +5 damage. The original goal of that Grenade was the vice mayor of Seattle but well many things happened that night you were on council island, things that I could never anticipate.
To be fair because there is a reasonable chance of such a grenade will knock kynos well into overflow. He should be alright as long as he remains alive as Finestra can heal him with a medic kit. Congrats for killing Venom tough!
