Cyrus: 0.80 PDur, 0.87 MDur, slow, regens 10% HP per turn. If using the t1-t4 average, he deals (if he unloads on the last turn) 0.51 damage on turn 1, 1.02 damage by turn 2, etc. His 3 BP zap is about 1.01 PCHP in a single turn for healer bustin'.
Cyrus (Octopath Traveler) vs. Zelos (Tales of Symphonia)
Zelos surely 2HKOs first.
Cyrus vs. Karin (Shadow Hearts 2)
Cyrus easily 2HKOs through regen since he's hitting an elemental weakness. Can Karin 2HKO back? Dhyer's topic seems to suggest "no", even her slower damage is a bit below average, arguably might hit the wrong defense score, and Cyrus has regen.
Cyrus vs. Teddie (Persona 4)
No vote, but I have to assume that Teddie is getting zapped by Lightning here, unless he has an amazing plan on turn 1.
Cyrus vs. Tony (Wild Arms 4)
While I'm skeptical of Tony elemental defense hype (the form that has it exists before you even have Blast, IIRC), don't see why he can't 2HKO first here and barely avoid a OHKO. Cyrus can equip for evade I guess, depends on how much Tony inaccuracy is hyped? Leaning this way for now.
Cyrus vs. Sage (FF3 DS)
I seem to recall Sage's agility being pretty dire, so Cyrus might actually outspeed here. That said, mildly above average magic defense = Cyrus isn't 2HKOing = Sage gets some turn 2 status to work.
Cyrus vs. Red XIII (FF7)
Faster, 2HKOs through the regen.
Cyrus vs. Kellam (FE Awakening)
If Cyrus doubled here, he could Defend -> KO off a 2 BP boosted Fire Storm doubled, but Kellam's not THAT slow, so he just 2HKOs instead. Cyrus could go for a YOLO evade set up but nah.
Cyrus vs. Lucca (Chrono Trigger)
Lucca switches to magic tank mode for this.
Cyrus vs. Cray (Breath of Fire IV)
They each 3HKO, but Cyrus is somehow faster.
Cyrus vs. Dave (Cosmic Star Heroine)
Cyrus 2HKOs. On one hand, Dave will have some style loss from going desperate, but on the other hand his "real" 3-turn in the DL is to inflict Vulnerable with Breach rather than use Cheat Code, which buffs his damage back up, so I think Null will still OHKO Cyrus on his 3rd turn while in Desperation.
Felicia's BR Flame Shuriken Maid form is a bit better than Strategist, so usually assuming that.
Felicia (FE Fates) vs. Zelos (Tales of Symphonia)
Zelos might OHKO, and is tanky enough to not be 2HKO'd? He does have WTD though. Inclined to see him as faster due to ToS mages existing though.
Felicia vs. Karin (Shadow Hearts 2)
Felicia should double and have counterattacks.
EDIT: Hmm, Random says Karin is a tad faster than average, and Maid move doesn't help her case for winning tiebreaks. If Karin goes first and isn't doubled, then she wins, sure.
Felicia vs. Tony (Wild Arms 4)
It's close, but I don't think Felicia 2HKOs even with the debuff, and that's that.
Felicia vs. Sage (FF3 DS)
Sage is getting doubled & debuffed & rams into Tomebreaker so not really sure what his plan is. Heal-locked at best.
Felicia vs. Red XIII (FF7)
Red 2HKOs, can Felicia 3HKO without waking up a limit? Nah, I'm not sure she 3HKOs at all, never mind evading the limit.
Felicia vs. Kellam (FE Awakening)
Kellam barely misses the OHKO to me, and he needs it as he gets horribly massacred due to range advantage doubles. Also no WTD for Maid Felicia here, just Strategist.
Felicia vs. Lucca (Chrono Trigger)
Felicia's BR form is nearly mono-fire which is bad news vs. Lucca (I guess allowing FELICIA'S PLATE would help?!), and even allowing Strategist her PDur is bad enough for Wondershot hype, yeah.
Felicia vs. Cray (Breath of Fire IV)
Felicia's preferred kind of opponent, yeah.
Felicia vs. Dave (Cosmic Star Heroine)
Huh, Felicia might actually want Strategist for the higher move range so she goes first here. Anyway, even Maid Felicia doesn't quite OHKO off her opening double, so she can't really stop Dave from doing his nonsense on turn 3, don't think Null gets hit by Tomebreaker and probably hits raw HP and not sure the Mag debuff even works against it. Strategist might force Dave to be desperate on turn 2, though, which might actually win as Dave would have to OHKO with an unboosted Null. Coinflip match that also has formchoice headache.
EDIT: Hmm, Felicia doesn't double average per Random, so I suppose that makes this a more clean win for Dave - if Felicia needs to wait 'till turn 3 to kill, she's in a bad spot.
Cyrus: 2-7, although probably 3-9 off Teddie/Juno/Gryz guesses (assuming Crash is turn 1 vs. Cyrus Strength, even despite the Fire weakness). Yeah seems safe enough for Light.
Felicia: 3-6. Yeah, not so great in Middle when she isn't spoiling, although still seemingly maybe too dangerous for Light?
