Zig Zagged: Blaze disappears shortly before battle, but arrives on the scene in time... but gets knocked out by a cheap shot while distracted.

Plotted A Good Waste: While it looks at first that Blaze is just being sidelined by the writers so Flik and the others won't get bailed out by him all the time, it's eventually revealed that he's been getting annoyed with how the others treat him and was considering a Face-Heel Turn.
Played For Laughs: Blaze was bragging about his strength and skill, annoying the others until Gusty smacked him upside the head... instantly knocking him out. Whoops.
Played For Drama: Shortly before the battle, Blaze has a falling out with Flik and decides not to respond to this particular call.
