There really are very few words that can sum up the sheer crassness and awfulness of Ultimatum. While it’s true that almost all of the Ultimate titles other than Spider-Man were dropping off in quality, allowing the one writer whose title had shown the most precipitous drop to write a big universe-changing crossover was not the answer. Truly breathtaking in its banality and terrifyingly unconvincing in both its plotting and its characterisation, this reading order is included only for completeness’ sake.
It can be found here on the main timeline.
- Noteworthy solely for being the only title bannered “March on Ultimatum” that actually had anything to do with the story.
- This is also one of the stupidest names for a crossover ever: at no point does any of the alleged masterminds behind these events issue anything that even resembles an ultimatum.
Created by the eponymous Project: Mothervine, Mothervine represents yet another attempt to weaponize genetic mutation in the Ultimate Universe. A refinement of the original creation of mutants, it is a serum intended to be injected into pregnant women, causing them to give birth to mutant children. Jimmy Hudson, the son of Wolvernine and Magda, is the only known mutant alive today to have been affected by this serum during gestation (and his mutant blood is the sole remaining source of the drug).
In most cases, where neither parent is a mutant, the mutations caused by Mothervine will tend to remain latent unless activated by some trauma, or by the hearing of a passphrase that is somehow coded into the drug, and will cause immediate and uncontrollable activation of the mutation when heard. The mechanism of this encoding is unclear, nor is it known whether it transcends language.
Also known as the Source, the Serum was created by the scientists of the South East Asian Republic as a response the American and European Super Soldier Serum projects. They succeeded beyond their wildest dreams.
The Serum is a bright green liquid that is taken by injection, which mutates those who take it into terrifyingly powerful superhumans, so different from baseline humanity that they consider themselves another species (although it is unclear whether this is true or merely rhetoric). Several thousand of them already exist in the S.E.A.R. and they have created their own realm and invited any who wish to join them to do so. So confident are they in their power that when Nick Fury sent Hawkeye to steal a sample, they actually gave it to him.
