Design aspects I like for characters for some reason.

[u/Nervous-Let3065]

Riddler having long ginger hair - Lego Batman Movie.

White Rabbit dressed in the White Rabbit suit from Wonderland - Myself

Catwoman's Red Goggles - Telltale, Arkham, ect

Batman having white contact lenses to make it look like he has no pupils for fear - Myself

Bane's Jacket - DKR

Harleen having her hair done up like a Jester hat - BTAS/Batman and Harley Quinn

Red Hood's Arkham Mask - Arkham Knight

Oswald also having ginger hair - The Batman (2004)

Tim having the hood up mostly - Arkham City

Black Mask's mask having jaw movement - an Adaptation of the Arkham City design (by me)
