Fireball Eyeballs

Eyes filled with fire is a very strong image, and is a good way to convey that a character is demonic, possessed by demons, really pissed off, or is in just a really excited mood.

Don't really expect the fire to actually affect things, unless this crosses over with Heat Vision.

Compare Glowing Eyes, Hellish Pupils, Wingding Eyes, Burning with Anger.

Contrast Ocular Gushers.

Not to be confused with "Eyes of Flame".

Examples of Fireball Eyeballs include:

Anime and Manga

In Ouran High School Host Club, the female customers gets flaming eyes when they're really fired up about something - usually a particularly adorable Moe moment involving the hosts. It turns into a somewhat bizarre plot-point during the episodes starring Ritsu Kasanoda, a young Yakuza Boss whose icy glare normally freezes anyone who comes near him. He winds up being Sweet on Polly Oliver, causing all the girls to get fired up about the perceived Yaoi romance, and even when he turns his icy glare on them, their fiery intensity melts it on the spot.

In one episode of Sgt Frog, Momoka's pupils turn into flames when she imagines using the next day's outing with Fuyuki as a chance to get close to him, but they turn into tiny rainclouds when Fuyuki mentions it's supposed to rain the next day.

Two examples from the Percy Jackson series. Ares, god of war, has creepy flaming eyes because he's a representation of violence and rage; he normally wears sunglasses to cover them up. Hestia also has flames for eyes, but hers are described as much warmer and less creepy; since she's goddess of the hearth, the literal "home fires," this makes sense.

Girl Genius, when Agatha was in "god mode".
