Equinox (Marvel Comics) (Spider-Man enemy)


(Terry Sorenson)

Power Level:
Game system: DC Heroes Role-Playing Game


Equinox is an obscure Marvel Comics character, whose main historical appearances were in 1974 and 1977. When I read these stories back then I thought he was awesome and had an awesome name but, as Dr. Liara T’Soni once said – “I was… very young !”

As a result I also wrote him up quite early, which means that this entry is really old and should be overhauled. Especially since he’s had further appearances since I wrote this stuff.


  • Real Name: Terrence “Terry” Sorenson.
  • Marital Status: Single.
  • Known Relatives: Dr. David Sorenson (father, deceased), Dr. Margay Sorenson (mother).
  • Group Affiliation: Villains Anonymous.
  • Base Of Operations: New York City.
  • Height: 6’ Weight: 200 lbs.
  • Eyes: Yellow to red (brown in human form). Hair: Bald


Powers and Abilities

Equinox is always absorbing vast amounts of heat and cold. The phenomenon starts at his feet and ends at his head, so a part of his body is always covered with flames and the rest with ice. He undergoes a full “sweep” every 6-7 seconds or so.

When he absorbs mainly cold, he’s mostly ice and can shoot bolts of flames. When he absorbs mostly heat, he’s covered with flames and can shoot ice.

Equinox is good at ambushes and the general use of his environment against his enemies. An efficient tactic is to blow up gas trucks in the middle of the fight, since he’s immune to flames.


Equinox is the son of a researcher in thermodynamics. However, his father, while brilliant, did not gain any recognition due to his unorthodox approaches. On the other hand his wife Margay was quite famous in the field of natural sciences. This caused tensions within the couple and David Sorenson started to drink.

While drunk, he caused an accident in his lab. It killed him and turned his son Terry into the being known as Equinox.

Margay Sorenson started studying thermodynamics in order to cure her son and managed to build a containment suit. However, funds were lacking and the increasingly erratic Equinox resorted to bank robbing in order to help his mother cure his condition. The Human Torch and Iceman started to investigate. While at first they thought each other were guilty (of course), they fought Equinox.

Later, Spider-Man, the Wasp and Yellowjacket fought Equinox. The whole fight went against the heroes, but they won by giving it their all. Spider-Man refined the latest invention of Margay Sorenson, whom her insane son now savagely hated since she was attempting to cure him. And thus they managed to neutralise Equinox. That was in 1977, and Equinox hasn’t been seen since AFAIK.



Equinox is a bulkily built man who’s constantly covered by ice and flames. His body is constantly changing its thermodynamic properties. Thus, parts of his body constantly change between being ice-covered or flame-covered. His eyes are visible, but instead of having visible hair his head is covered by the usual fire or ice.

Curiously, Equinox lacks ears and instead has two pointy things going up from his forehead, giving him a real inhuman and horrifying look.


Equinox is an insane, violent, megalomaniac villain with an unstable personality. This is mostly caused by his strange condition affecting his mind – he’s not intrinsically evil. However, his insane rantings and systematic violent attacks at anything that frustrates him do not make that fact obvious.

Equinox also has a soft spot for Margay Sorenson. This can be used by her to try to calm him down while on a rampage. In highest probability the reason for his insanity is the loss of his human form and receiving the form he now permanently is trapped in.

DC Universe History

As with all the characters requested by Sean, Equinox is a minor character and could be used everywhere. He could make a good, powerful foe for Fire & Ice of the early 90s JLA.
