In addition to normal weapons, Blazes can be hurt by snowballs, taking 3 (1 1/2 hearts) per hit. If they have found a way into the Overworld, they are also damaged by water and even rain: Water does roughly 1 damage every second. Like all Nether mobs, they are not damaged by fire or lava.

In the Season 5 episode "The Blaze Family," Blaze reveals the he has a family: a mother, a father (with an unknown name) and a little sister named Sparkle (who could possibly become a future main character in the series).
