This is Goldar from the Mighty Morphin' Power Rangers Series. Goldar is a humanoid monkey with red eyes and a gravelly voice.
He is a powerful yet very overconfident warrior that served under the command of Rita Repulsa and Lord Zedd. Goldar sports a golden suit of armor with a matching helmet.
This is an improved version of my previous Goldar cosplay.
I added a lot more gold, removed a lot of items, changed the eyes, and added the death whisper (wing) pose.
