For a long long time batman had always known that robin had gay tendencies since they became partners fighting crime as super heroes batman always suspected of robin being gay

one night after they fought some villains in gotham batman gave robin some green potent serum that he told him would give him super strenghts

robin drinks it and he shrinks instantly then batman humiliates robin stomps allover him and makes him be his bitch batman will no longer need robin to fight villains anymore!! ha ha
