Ultimate Marvel recreated several characters from the Marvel Universe. In many cases the new ones were quite stronger than the originals.
- Ultimate Fantastic Four:
- Willie Lumpkin went from a senior citizen mailman in the main Marvel Universe to a Colonel Badass.
- Doctor Doom is shown gaining superpowers in the same accident that created the Four rather than using Powered Armor against them.
- The Ultimate version of Reed Richards has powers of elasticity that are much more versatile compared to his original counterpart. Examples include stretching his eye lenses temporarily so he doesn't need glasses, stretching his brain to make problem solving easier, being able to breathe in the N-Zone where the air was acid because he had no lungs, no longer requiring food, drink or even sleep and being able to split himself into separate beings. These abilities make him very dangerous when he becomes the villain known as the Maker. He's been shown durable enough to survive a nova blast from Johnny and having his brain blown up by Sue.
- Unlike his comic counterpart who is often portrayed as weaker than the Hulk, Ultimate Ben Grimm is stronger than his universe's Hulknote . It is stated that the only ones in the Ultimate Universe physically stronger than Ben are Ultimate Thor and Ultimate Namor. Eventually he is able to change back to human form and gains the ability to become a being of purple energy than can walk through Sue's force fields.
- Ultimate Spider-Man:
- The Green Goblin is much stronger than his 616 counterpart, being a hulking monster as well as pyrokinetic instead of using pumpkin bombs. The same goes for the Hobgoblin.
- Dr. Octopus has similar powers to Magneto, being able to control any metal.
- Subverted with Mysterio as Spider-Men revealed that the "Mysterio" who operated in the Ultimate universe was only a series of robotic avatars the Mysterio of the main Marvel universe used to operate in the Ultimate Universe, with the combination of dealing with less-experienced heroes and no one knowing who he is enabling him to take bigger chances than he would on Earth-616, such as killing the Kingpin.
- Ultimate X-Men (2001):
- While Kitty Pryde lacks her mainstream counterpart's computer skills, she has used her abilities to make herself denser so she has superhuman strength and durability.
- Magda is not just a helpless victim of Magneto, but a resourceful spy.
- The Phoenix is a top-tier cosmic entity in Marvel, but here it's got a few extra powers, like being able to actually resurrect the dead, and rewrite reality.
- Toad has a prehensile tongue, and he can actually give a fight to the X-Men. This was similar to the changes done to the character in the contemporary X-Men film.
- Multiple Man. His use in Ultimatum (both the X-Men tie-in and the event itself) shows exactly how dangerous a man who can make an unending number of copies can be in the right (or, in this case, wrong) hands.
- The Ultimates
- While his mainstream counterpart always skirts the line between Peak Human and then some, Ultimate Captain America is an outright superhuman, strong enough to stalemate Spider-Man and give the Hulk a good fight.
- The original Hawkeye has absolutely no powers, and his Improbable Aiming Skills are the result of training. Ultimate Hawkeye has enhanced vision.
