Manterei has this very sleek, evil look to him. Well I think he looks evil as most of the I see Manta Rays used in animation they are the bad guys (think Tigersharks). Then again Depth Charge in Beast Wars was a Maximal. Regardless of Mantarei's actions, this is one sweet figure.
I love everything about this figure. From the animal sculpt to the blue armor. The harness on his head is fantastic looking and gives the appearance that he has built in lights for those battles deep on the ocean floor. Like with most of the Beast Saga figures, the sculpting from top to bottom is great. I challenge you to find anything negative with this figure...outside the weapons. Mantarei gets shafted in the weapons department and is handed down the drill tipped spear type weapon and generic round shield.
Mantarei makes a great addition to the Kingdom of Death Sea team. He's got that sinister, evil look going for him. Plus it's a Manta Ray humanoid creature wearing a suit of battle armor wielding weapons. Really, what more can you want?
