This blog will follow one straight timeline, although it occurs in multiple realities. I will indicate in each entry which reality (or realities) they occur in.

August 1896--PREDATOR: NEMESIS--TVCU--An alien "Predator" is killing in London, but his murders are blamed on Spring-Heeled Jack.

Eventually the military blows up the town to eliminate the threat. Weyland-Yutani ends up with some alien technology.
2003--BATMAN: DEAD END--DC MULTIVERSE (UNCLASSIFIED)--Batman and the Joker face an Alien and three Predators.
2007--GREEN LANTERN VERSUS ALIENS--DC UNIVERSE (PRE-INFINITE CRISIS)--The Green Lantern Corps discover the Aliens in sector 1522, where they had killed the Green Lantern of that sector. They find the best way to contain this menace is to transport them all to the planet Mogo (which is both a living planet, and a Green Lantern.)

2008--SUPERMAN/ALIENS--DC UNIVERSE (PRE-INFINITE CRISIS)--Superman discovers the remains of survivors from Krypton who had been killed by Aliens. The only one to survive (well, at this point in the story) was a young blond girl named Kara. Note that this story is later referenced as having happened in Superman's regular series, guest starring the Legion of Super Heroes and being a Final Night crossover, thus the reason I place all DC/Alien/Predator crossovers in the DC Universe.
2009--BATMAN VERSUS PREDATOR III: BLOOD TIES--DC UNIVERSE (PRE-INFINITE CRISIS)--Batman and Robin take on two Predators.
2009--WILDC.A.T.S/ALIENS--DC UNIVERSE (EARTH-50)--WildC.A.Ts existed in the Wildstorm Universe, which DC designated as Earth-50, and then recently integrated into their mainstream universe. This crossover was actually occurring between inssues of WildC.A.T.s and Stormwatch and the events of this crossover story led to events in the regular series.
2009--BATMAN/ALIENS--DC UNIVERSE (PRE-INFINITE CRISIS)--Batman first encounters Aliens when working with mercenaries in Central America.
2009--SUPERMAN/ALIENS 2: GOD WAR--DC UNIVERSE (PRE-INFINITE CRISIS)--Darkseid uses the aliens in his war against New Genesis.
2009-BATMAN/ALIENS 2--DC UNIVERSE (PRE-INFINITE CRISIS)--A mad scientist combines Alien DNA with that of Arkham Asylum inmates.

2010--PREDATORS--TVCU/DOCTOR WHO UNIVERSE--Predators steal humans from Earth that are all trained killers in order to hunt them on a jungle planet. (Includes a comic prequel.)
2037-2040s AD--PREDATOR: XENOGENESIS--DOCTOR WHO UNIVERSE--Birmingham, England: The organization known as Spearhead is formed to combat Predators with state of the art technology. At the same time, Subotai, an immortal Japanese samurai, decides on a final showdown with the Predators. (date revised and roughly estimated by SpaceWuss. Must take place after AVP: Eternal, because London is now underwater, but was present in that story. BUT the the novel Predator: Forever Midnight states that in 2117 it has been "nearly a hundred years without recorded incident" of any Predator appearances. 2037 would be 80 years pervious which, while pushign the '"nearly hundred years" comment, could still be said to be close to a hundred years. Though 12 years is pretty quick for the sinking of a city.) http://avp.wikia.com/wiki/Timeline
2099--PREDATOR 2099--DOCTOR WHO UNIVERSE--A Predator hunts during a civil war in the underdeveloped nations.
2119--PREDATOR VERSUS JUDGE DREDD--DOCTOR WHO UNIVERSE--See my comments on Judge Dredd's encounter with Aliens.
2122--ALIEN--DOCTOR WHO UNIVERSE--From time.absoluteavp.com: USCSS Nostromo encounters what is assumed to be a distress signal emanating from the planetoid designated LV-426, in the Zeta-2-Reticuli system. Captain Dallas, Executive Officer Kane, and Navigator Lambert investigate a derelict spacecraft that contains the fossilised remains of an unknown alien species, and thousands of Xenomorph eggs. One of the xenomorph spore (‘facehugger’) attaches itself to Kane’s face and plants an embryo in his throat, which then hatches, killing the host. The hatchling (‘chestburster’) grows to over 7 feet tall and kills Dallas and Engineer’s Mate Brett.
Warrant Officer Ripley discovers that Weyland-Yutani want the Alien specimen and the crew of the Nostromo are expendable. It is revealed Science Officer Ash is in fact a Hyperdyne Systems 120-A/2 android, who has been protecting the Alien. Chief Engineer Parker renders Ash inoperative when Ash attacks Ripley. Parker and Lambert are killed by the Alien whilst evacuating the Nostromo. Ripley rigs the ship to self-destruct and escapes on the shuttlecraft Narcissus with the ship’s cat Mr Jones. The Alien also escapes on the shuttle, but Ripley manages to blow it out of the airlock, effectively killing it. See http://time.absoluteavp.com/ for an excellent Alien timeline.
2125--JUDGE DREDD VERSUS ALIENS--DOCTOR WHO UNIVERSE--The title is pretty much self-explantory. Note that I'm not that familiar with Judge Dredd (I saw the movie), but from what I do know, it doesn't seem that the future of Judge Dredd really contradicts that of either Alien or Doctor Who. But please tell me if I'm wrong and I'll make a correction.
2179--ALIENS--DOCTOR WHO UNIVERSE--Ellen Ripley wakes up from suspended animation and gets sent out by "the company" to go fight more Aliens.
2179--AVATAR--DOCTOR WHO UNIVERSE--This film features the Colonial Marines working for "the Company", just like in Aliens. They both use similar type human controlled robot machines, and they are both directed by James Cameron. 'Nuff said?
2179--ALIEN3--DOCTOR WHO UNIVERSE--Ellen is the last survivor, well, except for an Alien. They both end up on a prison ship where Ellen...dies.
2189--OUTBREAK/NIGHTMARE ASYLUM--DOCTOR WHO UNIVERSE--Featuring Wilks and Billie.
2381--ALIEN: RESURRECTION--DOCTOR WHO UNIVERSE--Ripley has been clones, along with the Aliens.
Late 24th Century--ALIENS VERSUS PREDATOR VERSUS THE TERMINATOR--DOCTOR WHO UNIVERSE--Comic mini-series pulls in the Terminator franchise into the Whoniverse. Note that the first two Terminator films and the SARAH CONNOR CHRONICLES occur in the TVCU. In the Whoniverse, at least the first two films occur, though the third can't since obviously Judgement Day has not come to pass. Likely the Whoniverse timeline is the timeline that includes John Connor becoming a U.S. Senator, and then the Rise of the Machines likely is tied into the third world war.
26th Century--FIREFLY--TVCU/DOCTOR WHO UNIVERSE--Weyland-Utani still exists in the future of Firefly.
c. 4000---PREDATOR VERSUS MAGNUS ROBOT FIGHTER--DOCTOR WHO UNIVERSE--Predators exist in the TVCU and the Whoniverse, but since Magnus has no TVCU connection, it must occur in the Whoniverse.
3,002,385--RED DWARF--"Psirens"--DOCTOR WHO UNIVERSE--In a ship graveyard is a Weyland-Utani ship. Weyland-Utani is from ALIEN. Weyland-Utani appears also in the TVCU, but considering that the Star Trek future is the main future timeline of the TVCU, it's possible that the future timeline of Alien occurs in the Whoniverse. Weyland-Utani is mentioned on Angel, however that is in the TVCU. In this episode an Eagle ship from SPACE: 1999 also appears, but that show does not work in either the TVCU or the Whoniverse. It's likely either a wormhole pulled the ship from an alternate universe or else this type of ship still existed in the Whoniverse.
