History[]
Working with Omni-Man[]
Shortly before Atom Eve's birth it was Art who provided Nolan of Viltrum with his Omni-Man costume. As he is helping the original Guardians of the Globe in a fight against the Lizard League, Omni-Man mentions to the Guadians that Art believed that his Viltrumite suite was not iconic enough, hence the bright red and the custom "O" on the chest. Throughout their time spent together Art and Nolan became friends, sometimes going on fishing trips. Art even kept one such photograph framed on his work station.
Meeting Omni-Man's son[]
Art Rosenbaum greets Mark and tells him it was a pleasure to meet him, and gets Mark excited. Art hands him a suit, but Mark was not sure about orange and yellow and wanted something more iconic, which Art understood. Art told him that he needed a name from him so he could grab inspiration from there, telling him to let him know later.
While Mark came in to Art's garage, he told him to get to work.
Finding Nolan had killed the Guardians of the Globe[]

Debbie visits Art.
Deborah visits Art, who tells her the news was not good. They look at Nolan's suit and find traces of War Woman's armor, parts of Aquarus, slashes from Darkwing, and friction burns from Red Rush. She tells him that that only proved that the Guardians and Nolan had fought, wondering if maybe they had attacked him first and was trying to protect their legacy. However, Art explains that blood begins to oxidize when exposed to air and saw that the oldest trace of blood on the suit was on Nolan's wrist, meaning he had struck first. Debbie asks him not to tell anybody, but Art mentions he was too scared to do it anyway. From outside, Nolan looks angrily.
Nolan angrily approaches Art from behind, but shows him a few beers he had bought. Nolan and Art share laughs while reminiscing about the past. However, he asks Art why he is a little nervous. Art tells him he is tired, and Nolan says he understands since he knew how things could change from one day to another and hands Art another beer.
Aftermath of the Battle of Chicago, Illinois[]

Art grieving over Omni-Man's betrayal.
As the news cover the death and destruction caused by Omni-Man during his fight with Invincible, Art can be seen listening to it on his television and grieving over it as he drinks his sorrows away. He is later seen working on another super-hero suit while glancing at a photo of him and Nolan fishing, which he then throws in the trash.
Debbie visits him and the two talk with one another. She explains that she never thought about what would happen after she found out Nolan killed the Guardians, and she still cannot believe that their time together was a lie, wishing he would come back. Art says he wished the same thing. When Debbie asks for a glass of scotch, he tells her he only has one glass, but she does not care, also wanting to drown her heartbroken sorrows in drink.

Eve & Art asking Mark & Amber why they are not with each other right now?
Helping the broken pups[]
Debbie is greeted by Art. Debbie's mind is still in free fall, but Art cheers her up by claiming that she was the strongest out of the three, doing the arm and leg work, while Nolan was out and about elsewhere in other cities and countries.
Two months later, Mark goes by to the Talior Shoope to ask some advice from Art, specifically Girlfriend Advice. Art claims that, super powers or not, people will always have difficulties with dating. Art asks why Mark isn't with Amber right now and should be with her. Art also offers sympathy to Mark about Nolan's fate on Thraxa. Mark asks if he has certain books written by Nolan. He does and gives his collection to Mark.
A new suit[]
Some time after the Angstrom Levy fight, as well as Mark quitting to work for Cecil, Mark along with Oliver went to the tailor for some new gear. Oliver was given a red and black costume with a stylized "O", similar to Omni-Man's. According to Art, he had been told by Oliver that the letter stood for his own name, leaving Art bewildered at Oliver's proposed hero identity of Kid Omni-Man.
Abilities[]
- Super-hero costume designer: Art Rosenbaum is a professional tailor and costume designer with a high knowledge of dense and highly resistant fibers. As such, he is capable of producing high quality costumes for various super-heroes, able to withstand hard impacts, intense burns, friction and various other hazards. This is shown given that Mark's Invincible costumes could withstand being hit with concrete bricks, burned in molten lava, fire and even flight at mach speeds without sustaining any damage for prolonged periods of time.
- Forensic Detective Skills: His knowledge in super-hero costume design lent itself in the field of forensic science. Art was able to deduce the outcome of Nolan's battle with the original Guardians, as well as their deaths, after having studied the damage inflicted upon Omni-Man's costume. To do this, Art showed good use of several devices used for analysis.
