Monster Allergy is an 2006 Italian animated series produced by Rainbow S.p.A. based on a comic book series that was published by Disney Italia. The series aired on Kids’ WB! in September 23, 2006. It aired with a separate English dub rather than the English dub that was produced by Rainbow S.p.A which aired internationally outside of the US. The US-produced English dub has long since never been re-aired, and footage of it is nowhere to be found on the internet. Streaming websites such as Netflix use the Rainbow S.p.A. dub.
