BAT REM... may or may not ever come back...
but Robin is Anubis Jr... (Still awesome)
Dark/Dark Batman is 2hp/atk for dark (puts him on par with ares and other greek 2.0) and delay skill
The Dark/Light batman is a nice sub with 2 turn delay skill..
Catwoman... is garbage
Dark/Blue batmasn is... no thanks.
3 of 5 good... but most likely to get Catwoman over and over
So I just looked at my JP/US box after last set of Twinlits farming...
JP Finished: B/D Vampire, R/L Horus, B/L Isis, L/L Angel, G/L Alruane, R/D Shiva,
JP Want: D/R Bahamut (3 dark) L/L Zeus (3 dark and 3 light)
9 Angelits
14 Devillits
5 dublits
7 Tamadras (42 spent)
US Finished: D/D Hera, D/L Zeus, B/D Vampire
US Want: R/L Horus, B/L Isis, L/L Angel, G/L Alruane: 8 Angelits.
20 angelits in box now
14 devilits in box now
13 dublits (FINALLY!)
6 Tamadras (21 spent)
In case anyone is interested, someone else did the math and it turns out to be favorable to D/L Evo your Zeus and then reverse the busty and finally to L/L evo when about to max. I am not sure on the specific level needed, but I am sure its out there somewhere.
