Running with Bryce's idea of having Deadpool trying to take advantage of the attack on Castle Doom, I'm trying to come up with a plot behind the scenes to explain all this: the 'malfunction' of Doom's satellites causing the Venom attack, for the purpose of distracting Doom enough to allow Deadpool to get in the castle and steal something.
I'm thinking that someone a) really wants some technology that Doom has developed, and this is their complicated scheme to get it or b) somebody wants Doom in trouble for some reason so framed him for the Venom attack, and then will use some device stolen from Doom to make him look even worse.
The person behind the scheme would have to be able to: hack Doom's satellite control system, know when Doom was gone in his time platform, know where to find the object of their desire in Doom's castle.
The person would also have to either a) not have many resources to pull from if their entire plan depends on only Deadpool, b) be trying to do this in secret, and so not able to use their customary resources.
I have a vague thought that it could be some being that is able to inhabit/affect electronic systems, but has no body. That would explain their ability to get into Doom's systems, yet not have much to draw on to get things out of the castle. They may be interested in his robotics technology. I know there's several such bodiless beings in Marvel but they're not coming to mind.
Or it could be a rather minor villain. Or even someone like Iron Man trying to do something in secret. I'm open to any brainstorms or suggestions about who it could be or what they could be after. Thanks
