|First Appearance||The Purge|
Ignacius Baumann is a local shop keeper in Bellwood.
In Ultimate Alien, Mr. Baumann wears a light blue shirt, a black t-shirt, and black pants with a white apron. He is partially bald and has gray hair on the side of his head.
In Omniverse, Mr. Baumann wears glasses, a dark pink bow-tie and a light pink-striped yellow shirt with a dark pink apron and brown pants. He also has grown a little black mustache. He also has a pot belly.
In Ultimate Alien, he was shown as being friendly and nice to Ben. During Omniverse however, he came to grow an irrational hatred of Ben for any damage to his property or car that was never intentional. He is shown to have a cold, unforgiving and impatient demeanor towards Ben. He is generally unreasonable, as shown in Special Delivery, when he scolds Ben for another accidental destruction of his car that was the result of an unprovoked alien attack. Despite that, he often helps Ben's team by hiding them in his store during the Incursean occupation.

- Apparently he had more off-screen run-ins with Ben when he mentions that every time Ben shows up, the store always ends up being trashed during a fight, or how Ben has constantly destroyed his car since he was 5 years old in their first meeting.
