The event has been a popular staple of the Offaly Libraries calendar since its launch in 2019.
Comic-Con is coming to the midlands this weekend.
Dungeons and Dragons sessions, LEGO and art workshops and Viking battle and Medieval duel demonstrations will be on offer in the Tullamore Library tomorrow.
Prizes will also be up for grabs for anyone entering the Cosplay Competition at the free event.
Visitors will also get the chance to hear discussions on Pokemon Cards, and other collectibles, with doors opening at 10am in the morning.
