ENEMIES OF THE JUSTICE LEAGUE/ARKHAM CITY SKIN IDEAS
If you haven't seen my discussion for Justice League skins go to http://boards.na.leagueoflegends.com/en/c/champions-skins/Aqdv3VPm-justice-league-skin-ideas
so when i was thinking about Justice League champs i thought who they can be against so here are some skin ideas for the enemies of Justice league:
TOP
JL: 
as Bane (its already made an its batman enemy, fits good)
AC:
, 
, or 
as Solomon Grundy (dont want to make bane top again hes for JL and they all fit for grundy)
MID
JL: 
as Ares (he would look like an ares cuz of Injustice so it makes sense)
AC: 
as Catwoman (do i really have to say anything about this: hot, has hops' and kicks ass, they fit)
SUPPORT
JL: 
as Doomsday (both are rocky and tough so ya makes sense)
AC:
as Poison Ivy (doesnt really need an explanation just is what it is)
ADC
JL: 
as Lobo (idk i couldn't find anyone else and i remember playing injustice and graves came to mind when playing lobo)
AC:
as Harley Quinn (personality-wise they are very similar and both are like adc to me)
JUNGLE
JL: 
as Joker (its like zyra it just fits)
AC: 
as Scarecrow (there are both scarecrows well kinda but you get the idea)
Leave comments if you have better idea :)
as Cyborg but idk
:)
lighting ult and both are man child
e and lightning bolts as his axes
Deathstroke
Lex Luthor
