Went through everything on the front page and the ones listed under canon or edit-to-canon. And the ones I could remember that were elsewhere (basically the Old Guard and the Hyper Evolved Scorpion), plus the recent in-thread ones from crys and Lost. Listed in roughly that order, top to bottom. Parentheses say who has it and how to find them in the list; square brackets give some of my comments (I had more, but didn't feel like writing them all out).
MG-scan (Samael)
Multi-Target (Aquila, Shining Key)
Ability Synch (Pilot) (PFrame/Progenitor Golems)
Cleave (Solid Drive)
Time Walk (Void) [probably not the same as the mortal version, especially given the N/A MM. Looks like actual time travel]

Splinter (description of Splinter & Combine)
Analyse/Analyze (Professor ElRoi, Shining Scholar)

(Necromancy) (Horseman of Death)(The Four Horsemen)
Ritual (Horseman of Death)(The Four Horsemen)
Plagued (Horseman of Pestilence)
Immobilize (Shining Scholar, Crystal Mage) [The two use it differently; Crystal Mage's version might just be Lockdown]

Disarm (Magus of Bravery)(Team RESEARCHER)
Mind Control (Magus of Ambition)(Team RESEARCHER)
Extend (Luxuria)(Seven Deadly Sins)

Copy (Invidia)(Seven Deadly Sins)
Slow (Silent Murder, Crystal Mage)

Spell Scan (Illuminator)
Generate Spell (Illuminator)
Protect (End-Bringer)
Immortal (End-Bringer)
Debuff Resilience/Damage (End-Bringer)/Reduce Resilience (Nightmare of the Night) [we don't have named Abilities for Spells which are straight stat decreases, do we?]
Status-Infliction (End-Bringer) [What's this supposed to be? A variable status effect?]
Zap (End-Bringer)
Overload (Raging Heart, Nightmare of the Night)
Multi-turn Cast (Raging Heart, Nightmare of the Night) [Could replace with Total Charge, not too different]
Armageddon (Night Sky, Nightmare of the Night)
Target (Grey Skies)
Target(all) (Grey Skies) [What are these supposed to be?]
Scale Stun to Distance (Priestess of the Moon) [Might be better handled as Stun plus either a soft-mechanics or explicit scale-with-distance effect]
Bounce (Moon Rider) [Might be Ricochet]
Hazardous Terrain (Crystal Mage)
Swarm Networking (Machine Code) [Might be better as a personal Ability]
Total Control (Machine Code)
Full Round Action (Nightmare of the Night)

Zumwalt-class) [If it's different from Intercept]
Quick-Fix (Limitless Horizon)
Tracking (Shining Key)
Freezing (Shining Key) [Might be the same as Freeze]
Straight-Shot (Shining Key)
AOE (Shining Key) [Why is this an explicit Ability?]
Single-Target (Shining Key) [Same question. Though we can probably ignore Shining, since she became Brilliant Key]
Move Boost (Wild Heart)
Spellbook Lockdown (Wild Heart)
Eject (Mageslayer) [Super Ability]
Variable Damage (Dark Steel)
Limited Durability (Dark Steel)
Variable Speed (Dark Steel) [These three seem kinda pointless as explicit Abilities]
Boost-Weapon (Dark Steel)
Override (Dark Steel)
Multi-Cast (Dark Steel) [Actually, why is
Unequaled Strength a Spell instead of an Ability?]
Intimidate (Snow Gourd)
Magical Girl Slayer (Titan Worm)(Happy Fun Stuff) [Another for the "special Slayer Abilities" list]
Auto Grapple (Hyper Evolved Snake, Hyper Evolved Scorpion)
Overheal (Equinox) [See my previous post for link]
There's also these, which are on non-canon sheets made by crystalwatcher:
Road Kill (Saint Nicholas)
Identify - Weakness (Saint Nicholas)
Match Opponent (Winter)
Countdown (Winter)
And some more things I noticed on my way through (along with a bunch of typos I didn't record):
Spell Boost says it adds both Base Damage and Magic Modifier to spells, but the one time we see it in action (Lucky in RADIANCE DRIVE) it only adds one number. Which might be a combination of the two. Anyway, it'll be relevant soon, so to clarify: does it add both, and are the two bonuses written separately or combined?
Carnage says Increase Stack, list says Boost Stack.
The list says Summoning, but the fourteen canon characters with it all say Summon.
Crimson Hood, Steel Monsoon, Good Hunter, and Invidia (Seven Deadly Sins) say Mode Change, which should probably be Mode Shift. I'm pretty sure there's at least one canon sheet that says Mode Shift, so just changing the list won't fix this.
Sylvan Mercy (Moores Family) has Debuff Removal, which should probably be Status Recovery. Also, should the Variable for both her and her mother be in parentheses?
Scale to Target (
Juggernaut Drive's spell and Limitless Horizon's) and Damage by Health (Good Hunter, possibly another person) seem redundant.
Proxy Caster is typo'd in the Docs version (as Poxy Caster).
Solar & Lunar Radiance don't have a link to where they show up in-quest the way M.E.C.A. Force does.
Forest Guardian (Team RIOT), Blue Minion (Evil Overlord), and Avaritia (Seven Deadly Sins) should probably have Rapid Recovery instead of Rapid Regeneration.
Freezing Primal's (The Primals) Creation should probably be Instant Manufacture.
Guardian Primal's (The Primals) Curse Removal should be Status Recovery.
Ignite, on Red Minion (Evil Overlord), Black Dragon (Hopekiller), Ira (Seven Deadly Sins), and Will'o'Wisp should probably be either Burn or Melt.
Gula (Seven Deadly Sins) should have Multi-Slash, not Triple-Hit.
End-Bringer doesn't need Debuff on
Liberating Light, Dispel is enough (if I'm understanding the intent correctly). And
Release My Power should have its Abilities' names updated (Instant Recovery and Status Recovery).
Sinful Sound's second Spell should have Boost-All instead of both Boost-Self and Boost-Other.
Grey Skies' Anti-Magic should probably be something in the Dispel sequence.
The post with Crystal/Inferno Mage has explanations for Slow, Hazardous Terrain, and (one version of) Immobilize.
Mageslayer's Spells still give her name as Wounded Warrioress.
Brilliant Key's Total Heal should presumably be Full Heal.
Also, I see Red Rose's front-page sheet has been updated. Thanks; that's one less reference tab to keep open.
