Examples of Knuckles sensing all forms of Chaos Energy (and other things?) so I can aggressively point here whenever people forget about it
I see this part of Knuckles' abilities forgotten way too often and it drives me insane so here
1: HE CAN SENSE THE MASTER EMERALD.
Very blatant. His entire gameplay in SA1 and SA2 revolves around this ability. He innately has the ability to sense the Master Emerald and its shards. Rouge meanwhile is given an Emerald Detector in SA2 to explain her gameplay.
2: HE CAN SENSE CHAOS CONTROLS.
He senses "some strange energy" right before Sonic Chaos Controls right in front of him. Essentially predicting a Chaos Control. IDK how else you could read this lmao he literally sensed a Chaos Control. (I swear I never see anyone talk about this ever grrr)
3: HE CAN SENSE SOL EMERALDS AND CHAOS EMERALDS.
This interaction in Sonic Rush confirms that he can sense both Sol Emeralds and Chaos Emeralds. For him to be able to mistake Sol Emeralds for Chaos Emeralds without seeing them, he has to be using some sixth sense, and has to be familiar with sensing Chaos Emeralds as well.
4: HE CAN SENSE FAKE/ARTIFICIAL EMERALDS.
(This is from a Sonic Station Live segment, unofficial translation found here.)
Knuckles goes looking for a mysterious Emerald presence, and finds Tails' fake Emerald. Pretty straightforward. Also, evidence of the Master Emerald itself being sentient and able to direct Knuckles to investigate anomalies. (I wish more people made use of that, too.)
5: HE... HAS A LITERAL TREASURE SENSE, APPARENTLY?
(This is from a story on the Sonic Channel website. Original found here, unofficial translation from Windii Gitlord's blog found here.)
This is... a strange one. A bit of an outlier. I assumed that instances of Knuckles sensing treasures were purely gameplay mechanics, but here he appears to literally sense a pair of combat gloves, which is completely unrelated to Chaos Energy. So I guess he can do that too? But maybe it's only because he was led there by the ghosts of his ancestors? Who knows.
Oh yeah. BTW, Knuckles gets sent dreams by his ancestors' ghosts. That is canon. Someone pls use that in some way lol
So anyway. There. A bunch of examples of Knuckles sensing all forms of Chaos Energy, not just the Master Emerald. Throw this at someone if they question the extent of this ability and want evidence lol
Au where Grian and Scar meet in space prison. Scar for being a smuggler/scrapper and Grian for thievery or something. They get put in the same cell. Grian immediately is trying to plan an escape, to which Scar is No Help, and he gets frustrated thinking he’s ended up with the worst cellmate in the galaxy.
Then Etho and Bdubs and Gem blast through the outer wall and break them out of their cell, and Grian realizes that Scar wasn’t helping with his plan because he’d already had one. He’d just been waiting on his crew.
So we all know and love those two panels of Mario and Peach having dinner and then leaning in for a kiss from that one weird Club Nintendo comic, but I feel like the panels that immediately proceed them are just as cute and worthy of recognition, so please admire them with me.
...The targoblin tried running from it, even in desperation; but it was impossible, since the ball of light would dash through the air and get in his path. He was running futilely, and the ball even displayed cunning personality by moving in and out of his way as if mocking him. At this, Arleas cursed, pitched forward, and tumbled down dragging himself through the mud.
Ben came running and stopped right by the magic sphere hovering at eye level. And Ben was amazed, gazing into the ball and analyzing it. “Blazes. What are you??” Then he grabbed it and kept contemplating it with sheer curiosity.
“You have advanced sorcery, creature,” Elradon said as he tapped his head with his staff and created a glowing helmet and band to neutralize him. “That will keep you from more mischief.”
“Aarrgh!” snarled the targoblin named Arleas. “Free me at once, you foolish and broken-down geezer!”
Then he tapped his mouth and glued it shut, “There! You shall not spew more drivel.”
And as the mystic magically handcuffed him again, Ben pulled him up and added, “But his hands! They were tied. How was he able to use magic to escape?!”
“Well, he’s not just any targoblin. I can see that now,” the wizard explained while helping Ben drag Arleas back to camp. “Most can only do magic by the use of their hands. This is the lowest sorcery. But advanced sorcery requires the use of mental images and words. This seems to be his level.”...
