Let's see...I can see the Gerudo symbol from Ocarina of Time, the Puppet's mask from FNAF, and Tron Bonne's skull symbol. The paintbrush is making me think of Kirby, but that's a pure guess on my part. The flower's probably Daisy's, given Peach's crown is on the Light version of this pic. The winged ruby and the robot in the centre, I've got zero clue on.
I can sense a general theme of antiheroism/villainy going through your choices:
* The Gerudo end up filling a villain and a hero role for OoT - on one end, Ganondorf acts as the game's main villain, responsible for wrecking Hyrule's shit, whilst on the other end, Nabooru, working with the rest of the Six Sages, seals Ganondorf's ass in the Sacred Realm after (depending on the timeline) Link either beats his ass into next week or dies facing him and becomes an impromptu Triforce Delivery Service in the process.
* Tron Bonne's a pirate in a family of them who's ping-ponged between serving as a hero and a villain
* The Puppet's a murdered-child turned Major Fucking Problem(tm) for Freddy Fazbear's Pizza, who gave the animatronics life and killed night guards left and right in an attempt to send William Afton's ass to Hell and put his victims' souls to rest.
The only one which doesn't fit that's Daisy, who instead acts as a tough tomboyish foil to everyone's favourite cinnamon roll, Peach.
Love the moody purple/pink(?) colour scheme for this - fits the Darkness part of this equation.
