Potential Aeon

[Kim Taehyung]

Braska's Final Aeon, without a doubt.

 

[Mikha]

A ronso.....

 

[Spidey]

my favorite monster CACTUAR...yah...just like the one in FFVII...go jumbo CACTUAR

 

[Raptorg]

a dark flan tbh

the only thing that could actually kill that one was Holy or armour break... and since none of the enemies have those abilities, makes it a strong ally
(or almost none, i do remember 1 enemy using holy, however, can't remember)

 

[Dark Tidus]

I would have Shinryu be a summon (Shinryu is the Calm Lands arena buffed up version of Evrea Atlantae). He is really strong has 2mil hp can use and attack that does about 40 hits each doing about 1k damage and also uses an attack that petrifies and you can't be immune to it.

 

[Acid]

Evrae, Sin or Braska's Final Aeon.

 

[Phoenix242]

Has to be Nemesis. That thing is just flat out deadly

 

[Tsutanai]

Hmm... Probably Penance, Yunalesca or Evrae. About the only things I had trouble with ('cept the dark aeons, of course. ;P)!
