Hm... Should I give a shit with ECO monsters? I have yet to find any collaboration monsters useful. I'm very tempted to just fuse away previous collaboration monster right now as they're taking up spaces. Any useful ones of note?
quoting myself from page 1:

The Change the World boss mob ( ECO Tiny Alma ) at the end has good stats if that is the effect you are looking for. If you already had a Yomi or Venus and they are a key part of your team then farming them for skillups is worth it. Max skill Change the World is much more powerful than unskilled since stalling is so hard for spike teams in high level content.
ECO Shabo Alma (evolved from the cactus mobs) skills up Fortoytops. Once the joke of the REM, the new final form of Fortoytops is actually core to the new Cu Chulainn 9x balance team. For example:
Cu Chulainn final form
Fortoytops new form
ADK new form
King Woodsie
Green Odin/ Awoken Zeus-Dios/Echidna (if you need more defense)
Cu Chulainn friend
Seems pretty good.
Also if you have a Pavarti, here's a way to grind skillups.
The Lakshmi and Flare Drall skillups also drop in the dungeon.You know if you want/need them,if you aren't sure then you don't need them.
Finally there is a rare invasion mob that can skill up Loki, but I wouldn't rely on this dungeon for that purpose. It's just a boost if you already are farming it for the other monsters.

In terms of them being useful leaders/subs-Tiny Alma is not terrible, but not great. Decent stats but not enough ATK for a burst team where you really want the Change the World effect.. Dumpty Alma is a reasonable mono-dark sub but like Loki is a real mess to skill up through this collab due to the invasion nature of the monster.The others have such poor stats -this collab is like a year old in the JP version at this point-it's not worth bothering with as subs.
