Heart Light

"Turn on your heartlight
Let it shine wherever you go
Let it make a happy glow
For all the world to see"
Neil Diamond, "Heartlight"

As dictated by the Rule of Cool, aliens, robots and magical creatures in fiction have a tendency to give off light from various places on their bodies, including eyes, mouths, veins, and markings. This trope is about creatures who have a single light source on their chest, which is usually either centred straight in the middle (as is the case with most robotic examples) or off to one side if it represents their actual heart. If the Heart Light shoots some sort of beam, it's a Chest Blaster.

Some forms of Chest Insignia may overlap with this trope if they glow or emit light. May overlap with Heart in the Wrong Place.

  • Sailor Moon's final form consists of her having wings and a Glowing lotus symbol on her chest.


  • Iron Man's power source resembles one of these.
  • The circles on the armor of The Mighty Thor are sometimes portrayed as glowing.
  • The post-Annihilation costume of Nova has these all over the place.
  • As shown in the page image, the Alpha Lantern Corps makes use of these. Most of them are both aliens and robots/cyborgs.
    • The Green Lanterns themselves sometimes employ this when the lantern symbol on their costumes light up.

  • ET has the organic variant, and is probably the Trope Codifier.
  • In all versions of Iron Man, the power source of the suit is the same as the magnet keeping the shrapnel out of his heart. In the film version, and most animated versions that came after the first film, the "arc reactor" in Tony Stark's chest always generates a light that can be seen through his shirt.
  • In Ra One, both (video-game escapee) villain and hero have these. For additional points, the villain's (red-glowing light) is in the center of his chest, while the hero's blue light is off-center, on the left.

     Live Action Television 
  • Ultra Series: Ultraman, no matter the incarnation, always has one of these. The faster it's flashing, the closer he is to running out of power.
    Narrator, Once per Episode: "The energy Ultraman receives from the sun diminishes rapidly in Earth's atmosphere. The warning light begins to blink! If it should stop, Ultraman will never rise again!"
    • There are some exceptions though, because the Showa universe Ultras only receive their color timers if they are enlisted in the Space Garrison. Since he is a scout charter, Ultraseven doesn't possess a color timer, and neither does his expy, Ultraseven 21. In the Mega Monster Battle: Ultra Galaxy Legends movie, civilian Ultras could be seen in the Land of Light without color timers, signifying that they are not part of the Space Garrison.

  • The song by Neil Diamond quoted at the top of the page is the Trope Namer, having been inspired after seeing the Trope Codifier "E.T."
  • Owl City's music video for "Shooting Star"
