Honestly, I think that each one of these Glyphs and circles has a Glyph or circle that is the opposite to it in some way. The Ice Glyph and the Fire Glyph are opposites for obvious reasons. The Light Glyph and the Plant Glyph are probably opposites since light on its own is energy that isn’t contained while plants contain the energy of sunlight within themselves. Also, I heard from Cartoon Universe’s Every Hidden Glyph / Spell In The Owl House So Far! YouTube video that the pattern that appeared in the fireworks in the episode ‘A Lying Witch And A Warden’ might be an Explosion Glyph since it appeared in a firework explosion. And I later noticed it in the episode ‘Wing It Like Witches’ and the episode ‘Follies At The Coven Day Parade’. I think that the opposite to the Explosion Glyph would be the Blank Circles which, as shown in the episode ‘For The Future’, Philip Wittebane AKA Belos used in his Glyph combo that opened the secret passage to his hideout. The Blank Circles probably represent the part of the canvas itself that they are drawn or carved on since within those Blank Circles is that canvas. So, Blank Circles would represent the part of the canvas they are drawn or carved on and, by extension, that part of the canvas just as it is in its intact state. So, the Blank Circles represent intactness whereas the Explosion Glyphs represent destruction which would make the Blank Circles and the Explosion Glyphs opposites. Also, I think that the Explosion Glyph would represent the explosion of the part of the object it is drawn or carved on rather than its own explosion because, unlike light, ice, plants and fire, explosions are forces of motion that control the elements like how explosions pushes out fire in a fire explosion, how explosions push out plants in a plant explosion, how explosions push out ice in an ice explosion and how explosions push out light in a light explosion. Also, due to all of this, I think that, in the cases of quite a few Glyph combos, if a person replaces the Ice Glyphs with Fire Glyphs, replaces the Fire Glyphs with Ice Glyphs, replaces the Light Glyphs with Plant Glyphs, replaces the Plant Glyphs with Light Glyphs, replaces the Explosion Glyphs with Blank Circles and replaces the Blank Circles with Explosion Glyphs, it would make a new Glyph combo that produces a power that is, in some way, the opposite of the power that the old Glyph combo produced before those alterations.
