You don't really need different squads for all of these though. So far, I've used three squads for all of them (as in I've used each of these squads at least once in each quest), and they all work. They're all basic Questing squads, and can easily OTKO each of these bosses.

Avant Lead   Shera   Tridon   Bestie   Hadaron   Friends: Avant, Chrome, Bestie, Krantz, Quaid, Hadaron, or anything similar

Krantz Lead   Bestie   Tridon   Quaid   Hadaron   Friends: Avant, Bestie, Krantz, Quaid, Hadaron, Chrome, or anything similar

Bestie Lead   Shera   Melchio   Hadaron   Quaid   Friends: Avant, Krantz, Quaid, Hadaron, Chrome, or anything similar

I'll break these into basic setups so people can sub in whatever units they happen to have that fulfill the same role. You might have stronger units to combo than I do.

Basically the only requirements in my squads are an ATK buffing lead or a friend (preferably with BB utility) and then a supplementary friend for an ATK and/or BB utility LS, and then a nuker (here it's Hadaron). In the case of Mora I actually have another squad I use sometimes, but most people won't be able to use it (Kira-Hadaron lead with 4 Hadaron subs).

Explanations: all three squads have the LS combination I mentioned above. Most people can complete this requirement if they're the right level and have a decent friends list (feel free to my page and add me if you need one of these leads for a friend). After that, you can use an elemental changer if you really want to. If you have Hadaron, you don't really need one.

Shera is in each squad not for the mitigation (unless no one crits and the boss somehow survives), but for the ATK buff, spark blanket, high DC, and BB buff, the last two to maintain BB momentum after a mimic. Bestie and Tridon are there to maintain BB momentum in case of a mimic. Basically Bestie and Tridon are replaceable for nukers if you don't have Hadaron and need damage.

If you have Hadaron (With his sphere. Don't be like some people and equip something like the Luna Laguliz on him. His sphere gives him crit damage and weakness damage, making him deadly to Eriole and Mora) and the LS requirement, you're basically set to OTKO each one of these if you can maintain SBBs up to the boss.

However, I understand many people don't have Hadaron. In that case, you'll need a combination of nukers to replace the subs like Bestie that I have in there. Here's some suggestions: Avant, Zedus, Korzan, Symphonia, Quaid (6 elements hits hard, and if you have the Spirit Tiara on him, it gets better), Kikuri (with her sphere for extra weakness damage against Eriole and Mora), Sefia (with her sphere for more Crit Damage), Chrome, Toutetsu (you might need to wait for his additional attack), and of course, the classic Mifune.

If you're curious about spheres, here's my usual setups for each of these units:

Avant: Dandelga, Heavenly Bud   Shera: Existence Jewel, Demon Core   Hadaron: Axe of Hadaron, Phoenix Crown

Bestie: Buffer Jewel, Cosmic Dust   Krantz: Twinkle Gem, Eshuon   Quaid: Spirit Tiara, Cosmic Dust/Fallacy Orb

Melchio: White Armor, Alzeon Pearl   Chrome: Batootha, Heavenly Bud

TL;DR: You need an some kind of ATK buffing leader (yours or a friend), be it ATK stat, Crit, or Spark, and any other Lead, preferably a BB buffer like Bestie, or another offensive lead. If you don't have one and don't have a friend with one, go to my page and add me. For these you need Hadaron. Every other unit is there to maintain BB momentum and provide sparks and contribute a bit to damage. If you don't have Hadaron, replace the unit I have in there with 2 or three nukers (you'll probably already have one leading or as a friend). Done.

So there you go, different OTKO squads. Have fun rocketing through levels.
