Helix

The helix is a symbol that appears quite frequently throughout the series. In Godsend, the symbol appears on the sword hilt and Ando Masahashi remarks that it appears to be a combination of two Kanji characters: (才 Sai) meaning "Great Talent" and (与 Yo) meaning "Godsend". During an interview at the Wizard World in Los Angeles, writer and Co-Producer Aron Coleite stated that it literally means "God sending great ability." Writer and co-executive producer Micheal Green stated that the writers know it as "the helix". This symbol frequently appears as a pattern formed by mundane objects, but it also appears on certain plot-significant items and on several characters:

Printed on the front of Dr. Chandra Suresh's book, Activating Evolution.
On a drawing of the future made by Peter Petrelli.
On a post-it note placed on Mohinder's recreation of his father's enhanced persons map.
As the logo of the Helix Comics Group, the publisher for Isaac Mendez' Ninth Wonders comic book.
- The logo also appears in the artwork of Ninth Wonders Issue #14 on a screen in Times Square behind Hiro Nakamura.
On various paintings by Isaac Mendez.
In Chandra Suresh's algorithm program to find variations in genetic code, formed by DNA proteins when the entire program is viewed on a computer.
In the pool at the Walkers' house after Mr. and Mrs. Walker were murdered by Sylar.
On The Haitian's necklace.
On Jessica's back whenever she surfaces as Niki Sanders' alternate personality. When Jessica is repressed, the symbol does not appear on Niki's back. This also appeared on a painting of "Jessica" by Isaac. The symbol was hidden under an extra layer of paint. Later on, Jessica hides the symbol (an apparent tattoo) under a layer of foundation makeup.
On the hilt of a katana once owned by 16th-century samurai Takezo Kensei, the earliest known manifestation of the symbol.
On one of Claire Bennett's schoolbooks when she takes it out of her locker.
Several times in Company Man:
- On a warehouse door at Primatech Paper.
- On the Primatech Paper model in a flashback.
- On the glass in the Bennetts' front door.

- On a picture of Kaito Nakamura and Angela Petrelli signifying their death in 24 hours. These 2 pictures were once apart of a picture with all the 12 founding members of The Company. The picture of Kaito is later taken as evidence by the NYPD after he is murdered by a hooded assailant.
- Peter is wearing the symbol as a necklace when he is found with amnesia in Ireland.
