Powers/Abilities: He was able to manipulate the ambient chronal energies using the inventions installed in his armor, allowing him to do many different things. He could open portals to the past and future, switch people in the present with their counterparts from the past or paralyze his foes. Unbeknown to himself, he was also able to travel into the future.


(Marvel Comics Presents#159/4) - Dr. Yesterday went to the Museum of Natural History because it was the best place to focus chronal energies. He thought about the people who told him that he couldn't turn back the clock. They had told him to face tomorrow with courage and dignity, but Yesterday wanted to show them that they were wrong. He wanted to save himself by making yesterday come to life again. He dressed himself up with his armor and entered the museum, where he met Slapstick who was visiting the museum together with his pal Mike Peterson. Yesterday attacked him and accidentally drew the attention of members of the New Warriors who were also visiting the museum. Opposed by so many heroes, Dr. Yesterday used his power over time to bring the skeleton of a Tyrannosaurus Rex to life.

(Marvel Comics Presents#160/4) - Yesterday told the shocked heroes that he would turn time inside out across the entire city. He left the heroes alone fighting the Tyrannosaurus Rex and began to flood the city with portals to the past.

(Marvel Comics Presents#161/1) - Dr. Yesterday continued with his plan, surrounded himself with an army of warriors from all times and began his march against the city. He defeated the heroes Rage and Speedball by freezing them in time.

(Marvel Comics Presents#162/2) - The army of Yesterday overran Slapstick, and along with Jeffries and Peterson he was soon frozen in time by the power of Dr. Yesterday. Turbo returned with Impossible Man who angered Dr. Yesterday by talking about fun. Yesterday attacked Impossible Man with a burst of chronal energy. Dr. Yesterday took off his helmet and told Impossible Man about the irony of his life. Dr. Yesterday suffered from a terminal illness. He wasn't able to turn his time back to a time when he wasn't sick and so he wanted to see the universe die with him by bringing all time to a halt.

(Marvel Comics Presents#163/1) - Yesterday talked about his research and the machines he could've created to tap into the chronal energies in Manhattan from the constant time travel done by the heroes, but all this still couldn't cure him. Yesterday was attacked by Slapstick who then tried to explain death to the Impossible Man. Yesterday was enraged by Slapstick belittling the tragedy of death and reverted Slapstick to a time when he was just powerless Steven Harmon. Turbo asked Yesterday why he didn't try this on himself and Yesterday explained that he would just change place with a younger version of himself. He would still die of the disease in the past of his younger version. Impossible Man wanted to know why Yesterday feared death and Yesterday tried to explain the frustration and hopelessness in his coming demise. He never experienced true love or enjoyed real accomplishments. He was going to die and saw that his life was a total waste. Meanwhile Rage and Speedball got free and started an attack on Yesterday. Speedball knew a way to show the Doc the truth about his future. Rage threw Speedball against Yesterday and the kinetic energy mixed with the technology in the Doc's armor showed Yesterday that he was going to live for a very long time. Yesterday began to cry and didn't understand how this was possible. Speedball told Yesterday to use his powers to travel into the future where he didn't exist yet and to find there a cure for himself.

Dr. Yesterday realized that this was possible, closed all time portals and travelled into the future to find his cure.

Comments: Created by Fabian Nicieza, Robert Walker & Scott Koblish

Although Speedball was named as Robert Baldwin in this story it wasn't him, as this story happened after the events of New Warriors Vol.1#50 where Darrion Grobe became Speedball unbeknown to the other members of the New Warriors. The change was revealed in New Warriors Vol.1#70.

Fabian Nicieza really has it with those contests. In Marvel Comics Presents#160 four scenes were shown from comics of the past and they had to be identified. Winners of this contest were David Pflugh and some guy named Jeff Christiansen.

What was the "Special Fabian Prize" Snood?
--I never received anything, not even a letter of acknowledgement. Maybe someday, 30 years from now someone will make reparations, just like he did with the creator of Humus Sapien.

Except the aforementioned scenes from the past there were also some other characters present from other times. The known characters were Devil Dinosaur, Moonboy and Abraham Lincoln. Besides them many other regular citizens and soldiers of different wars were present. Among those soldiers were also an unnamed Skrull and an Atlantean.
