Odie (SN) vs Kary (FF1) - Type matches be damned, Hold does Odie in.
Odie vs Edward "Edge" Geraldine (FF4) - I'm not so sure. Edge really loves having some Lightning resist equips, since type disadvantage on fists means he gets his ass OHKOed - and I think I also see Shurikens triggering counters. So, do I see Edge primarily as fist-typed or ranged-type? I think I'll tiebreak for the former (resistance doesn't save him from being 2HKOed and the disadvantage, both offensively and defensively, is pretty gross in that case). Certainly won't blame people voting the other way, though.
Odie vs Sabin Rene Figaro (FF6) - Good news: Odie doesn't OHKO Sabin at base. Bad news: he kinda overkills after you factor in type advantages.
Odie vs Yuffie Kisaragi (FF7) - Yuffie, however, I totally see as ranged. She borderline OHKOs Odie at base to me - after typing, she's probably landing something like 1.5x overkill. Tough luck!
Odie vs Edea Kramer (FF8) - Lots of status to choose from.
Odie vs Garnet Til Alexandros (FF9) - FF9 equipment nonsense.
Odie vs Claire "Lightning" Farron (FF13) - This is pretty gross. Type advantage means Light won't really 2HKO him regardless and a counter+Odie turn equal death. If she tries to stall (how the fuck, don't ask me), the limit eats her alive.
Odie vs Ronnie Bell (S1) - Dear god, OHKO. So many martial artists lining up for the slaughter in this pool.
Odie vs Luc (S2) - Offensive disadvantage means Odie misses a 2HKO and Luc avoids counters with The Shredding. Problem is Luc needs to 3HKO himself (healing means he's going to eat a Hellthunder string, and that OHKOs Luc regardless of typing), so let's see how this pans out... *mathmathmath.* Oh dear, even after type disadvantage, The Shredding is above average damage and Odie's not too special at taking magic outside typing (good RES, but tragic HP). Yeah, this works out for Luc.
Odie vs Borus Redrum (S3) - Laughlines.
Odie vs Sigurd (S4) - Noisy mountains -and- ranged damage.
Odie vs Mathias (S5) - Uh yeah not too sure the Lightning resistance works out too well, Mathias mdur ain't too hot and his damage looks especially putrid against type matching.
6-6. Think this is pretty representative. Odie's a fascinatingly weird slugger due to the mix of offense and typings, and both his advantages (powerful offense, excellent triangle advantages, counters) and drawbacks (reliance on Thunder damage, exploding to ranged damage, somewhat problematic speed) managed to see play here.
Dark Knight Cecil Harvey (FF4) vs Kary (FF1) - Hold.
Dark Knight Cecil Harvey vs Edward "Edge" Geraldine (FF4) - EDIT: wait, he's faster? Welp.
Dark Knight Cecil Harvey vs Sabin Rene Figaro (FF6) - ID.
Dark Knight Cecil Harvey vs Yuffie Kisaragi (FF7) - EDIT: My mistake. Still, don't really see this panning out too well for him, he can't chip and risks landing Yuffie into a L3 as is.
Dark Knight Cecil Harvey vs Edea Kramer (FF8) - Death.
Dark Knight Cecil Harvey vs Garnet Til Alexandros (FF9) - ID.
Dark Knight Cecil Harvey vs Claire "Lightning" Farron (FF13) - More ID. Even against resistance, Cecil is faster and -will- live for three turns minimum.
Dark Knight Cecil Harvey vs Ronnie Bell (S1) - ID.
Dark Knight Cecil Harvey vs Luc (S2) - ID.
Dark Knight Cecil Harvey vs Borus (S3) - ID. Borus isn't even among the evasive Zexen Knights - no notable Repel levels, no Shield Protect and no Parry. That's more Chris and Percival's alley.
Dark Knight Cecil Harvey vs Sigurd (S4) - ID.
Dark Knight Cecil Harvey vs Mathias (S5) - You know the drill.
9-3. Fast accurate ID makes you a Heavy regardless of whatever else you have. Without it, Cecil's a Middle, but we know how those things go.
Basilio (FE13) vs Kary (FF1) - Hold.
Basilio vs Edward "Edge" Geraldine (FF4) - At the absolute worst, Image spam and toss Fumas on doubles. Edge likely has the resources to make it work.
Basilio vs Sabin Rene Figaro (FF6) - I don't think Sabin doubles, and I see him triggering counters against Basilio. This gets -very- ugly -very- fast.
Basilio vs Yuffie Kisaragi (FF7) - Yuffie avoids counters, but gets 2HKOed and doesn't 2HKO back. Once again, don't think Bassie gets doubled here.
Basilio vs Edea Kramer (FF8) - Death.
Basilio vs Garnet Til Alexandros (FF9) - Blind is turn one and this already eases down on the pressure immensely. She doesn't 2HKO, so this is absolutely necessary.
Basilio vs Claire "Lightning" Farron (FF13) - Ouch. Light can even avoid counters, but Basilio deals too much damage.
Basilio vs Ronnie Bell (S1) - I suspect Ronnie doesn't even 2HKO Basilio. He might not 2HKO either, but he's faster.
Basilio vs Luc (S2) - Dear lord, Luc, 80% PC HP and sub-MUKUMUKU defense? I'm kneejerking a goddamn OHKO here.
Basilio vs Borus (S3) - Counter very likely tips this in Basilio's favor.
Basilio vs Sigurd (S4) - There's a pretty big split in slugging worth here.
Basilio vs Mathias (S5) - Yeah, I'm pretty sure Basilio res makes Funeral Wind turn one.
7-5. Feels Heavy enough, all things considered, and likely better than The Vaike. Being only two points below average AS rather than -five- saves his ass something fierce more often than not and that anti-physical slugfesting (running off from both counters and Counter) is rather scary. 'dat Res is awful against status, though, and this handed him his ass more than once in this pool.
