The Helix Symbol-Has anybody an idea of what it is supposed to mean or represent?..not just on the show....but in reality..thanks

Okay, erm the Symbol isn't known in reality I'm afraid. But, in the show, the Symbol has been frequently been in the show and is somehow linked to evolved humans. But, I think it means 'Godsend', due to what Hiro said in the episode 'Godsend' in Season One.

It's also meant to be a helix, you know a DNA helix. So it's like the heroes' DNA! Hope this helped!!

When I was in Science class the other day,drawing The Symbol, one of my friends said it was half of the DNA symbol which is kinda crazy. But since it means Godsend maybe that means these 'evolved humans' are sent from God to help us somehow. (As in save our world probably)

The Helix is part of your DNA. Look it up on Wikipedia.

Heroes Wiki says it's an RNA helix, rather than DNA. They're both involved in genetics, though, so I suspect the same interpretation applies.

It is the same symbol as you will see on Lana Lang on Smallville in some episode or other. I think she has two tattoo symbols on her back, one is the half helix- so why the same symbol on two different shows....fascinating....

Its a christian symbol encrypted. Try to make paper model of this symbol. Then brake it at middle and join. You'll get a fish which is a symbol of Christ
