- Spider-Girl is briefly banished to a strange dimension with Franklin Richards aka Psi-Lord by the dimension hopper/time-travel known as Spyral. I don't have a name for this place. (Spider-Girl #3)
- Cain Marko aka the Juggernaut is stranded along the Crossroads of Infinity while on a mission with the X-Men. (J2 #7) This appears to be the same place originally seen in Fantastic Four (vol. 1) #51, but I believe it's different from the Crossroads the Hulk is sent to in Incredible Hulk #300.
- Spider-Girl #10-11 depicts May going on a time-traveling journey to the past, specifically during the events of Amazing Spider-Man #25,thanks again due to Spyral. It's not clear if this caused any changes to the timeline, though the Human Torch seems to vaguely recognize Spider-Girl in Spider-Girl #3, so who knows?
- The Avengers travel to Earth-9907 in search of answers regarding the original Avengers team (A-Next #10-11). Thunderstrike stays behind to be with a version of his father, and Crimson Curse is apparently killed. It's first mentioned in A-Next #7 and from there we learn more about the original teams mission, which ended in tragedy.
- J2 -with the aid of Sorcerer Supreme Doc Magus- travels via the Crossroads of Infinity to a pocket dimension on a different plane of reality to rescue his father. They are later aided by the original Defenders, Doctor Strange, Namor and the Hulk. (J2 #12)
- At some point, American Dream, Freebooter, Kristoff Vernard and the Coal Tiger are pulled from time by the Destiny Force into the Destiny War as it unfolds at the Citadel At The End Of Time. The Destiny Force first appeared in Avengers (vol 1) #97, the Citadel At The End Of Time first appeared in Thor #245. (Avengers Forever #11-12)
- Spider-Girl and American Dream make a journey to Earth-9907 to enlist the aid of Thunderstrike, his father, and the aged Captain America of the MC2 (still fighting on this world) against Seth. (Spider-Girl #57-58)
- Thanks to the machinations of Loki, he and Hulk end up exiled to Limbo for eternity. (Last Hero Standing #5) This seems to be the temporal Limbo linked to Immortus, first seen in Avengers (vol 1) #2.
- The minds of both Reed Richards and Victor Von Doom are sent to the Crossroads of Infinity and lost across the entirety of time and space thanks to Doom's 'Infinity Device.' (Fantastic Five (vol 2) #5)
- Mayhem travels back in time from a dystopian future via an old Time Platform (nicknamed 'The Mulligan') to change MC2 history. (Spider-Girl: The End one-shot) Doom's Time Platform was first seen in Fantastic Four (vol 1) #5.
- American Dream is snatched out of time by the Elder of the Universe known as Tath Ki (aka the Contemplator) to help prevent a corruption of the Marvel 616 present by Superia. (Captain America Corps #1-5
I've not list the various trips to the Negative Zone; I'm saving that for another day. The MC2 Universe brushes shoulders with many aspects of the Marvel Multiverse, and it's only a matter of time before we see another crossover. If you'd like to suggest any additions or corrections, please let me know.
Until Spider-Girl punches a hole in the Space-Time Continuum, I remain
