The sequential arts banner means anyone from superhero creators to independent press artists and writers will be part of the eight-day event, which is to be hosted across the city and will end with a two-day comic convention.
This year the likes of designer and illustrator Olly Moss, artist and illustrator Adam Hughes, artist Tim Sale, illustrator and writer Isobel Greenberg, illustrator Babs Tarr and writer Scott Snyder are getting involved.
There will be signings, live art on stage, and meet and greets with free commissions and tutorials by artists.
Art and writing-based workshops for young people, talks and competitions have also been lined up, and there are several screenings of sequential films.
Movie poster design collective Mondo will be making an appearance and Matt Taylor from Mondo will be creating a limited edition Thought Bubble print, which will be revealed at the event.
Look out for the convention anthology, which features work by many of the artists and writers at the festival.
The festival ends with the two-day Thought Bubble Convention on 15 and 16 November when there will be a “cos play masquerade ball” and the British Comic Awards, which this year is being judged by TV presenter Jonathan Ross, film director Jonathan Entwistle, writer Jessica Hynes, actor Danny John Jules and Suzy Varty, a comic creator and tutor.
Thought Bubble runs from 9-16 November at venues across Leeds. For more information head here.
