Is major x some future reality Deadpool? Because he sure looks like he’s supposed to be.
Naw, but funny you mention Deadpool- there is different version of him who pops up named "Dreadpool" and has a more armor-like design. Rob makes an obvious in-joke (through the real Deadpool) that this is supposed to be Deathstroke. That's the only props I'll give him for this turd.

"Major X" looks more like a glorified Rob Liefeld Power Ranger to me. In fact the #0 issue has "Colonel X," "Private X," "Corporal X" etc. wearing the same armor with different colors.

I might have my timing off, but the basic story is as follows-
Major X is from another reality/dimension/whatever that was created or found and maintained (the story is so fucking confusing that's hard to tell) by some other super-powered being who I've never heard of before. Dude is dressed like a neon-colored purple ninja from American Ninja or something. He opens a portal to this dimension to lead mutants and Atlanteans away from humans so everyone can live in peace.
Anyway, one day Major X is driving around on his shitty motor bike that also happens to be capable of time travel (where did this come from? Where did ANY tech here come from, for that matter? They went to what is essentially a new world with zero technology available, lol) and stuff starts disappearing and crumbling around him. He is then joined by "M'Koy," who looks like a derpier version of the Beast, only grey and with red stripes.
They escape and go back in time to save their world. How are they going to do this? Beats me! Who cares! Rob sure doesn't! They end up in what I guess is supposed to be 1991 and confront Cable and a couple of X-Force folks in the danger room. Shitty fights happen and then it's all about Cable and Wolverine who just sort of pops up out of nowhere because why not. Major X is revealed to be Cable's son from the future. He's also black and has white hair, so HINT HINT about who his mother is. Deadpool also pops up and is well-known by everyone despite him being unknown or not even introduced during this time period. Dreadpool attacks and more fighting and

and shitty art and then Major X and Beast-guy go forward to 2019.
At this point I started skimming through most of it because of how bad it was. Basically the baddies are the Atlantis folks who hate the governing policies in the other dimension and some scientist guy. Old super-powered dude who founded the new dimension pulls a Yoda and just sort of dies/disappears and then some random girl introduced gets his power. It makes no sense whatsoever. Then the Atlantis people reveal that old-man Namor is with them and he summons a big fish monster and more fighting and shit and who fucking cares.
The only other thing to note here is that 1991 Cable acts like he knows about all of this stuff and is not surprised to see his son despite never having mentioned him before or after. Despite the fact that Cable was killed and replaced by a younger version of himself a year or two ago, an "old man" version of Cable pops up with a mohawk and ZZ-top beard to help Major X at the end.

They meet Storm, who doesn't really seem to care that she has an adult son running around who was born after fucking Cable (when did this happen?

) and Major X goes off to do whatever and this shitty comic is over. BUT WAIT there's the #0 issue, which after having a brief story with Major X and the other Power Rangers, then changes to...a Wolverine story. WUT
I give it five Robs out of five and really have to wonder how anyone approved this for publication.
