Need help removing last character of every line if certain character

I need help removing the last character of every line if it is a certain character. For example I need to get rid of a % character if it is in the last position.

Input:

Code:

aaa%
%bbb
ccc
d%dd%

Output should be:

Code:

aaa
%bbb
ccc
d%dd

I tried this but it gets rid of all of the % characters. I just need the last one:

Code:

awk '//{gsub(/A$/,"")}{print}'
