How About A Double-bladed Scythe?

How about a double-bladed scythe?

One, to represent his double-bladed sword, his signature weapon (also represents his living a double life).

In addition, I say make it a scythe to represent his massacre of the 13 Primes, not unlike that of the Grim Reaper. After all, the death of the Thirteen is a canon event in every Transformers universe. (Oh, and here's my favorite particular double-bladed scythe for reference :D)

Another reason I chose a scythe: the blades are the shape of a cresent moon, which is the symbol of the High Priestess tarot card:

I think the High Priestess suits Sentinel more than, say, the Emperor, or Moon (ha you could also say the cresent can represent both cards!), because it doesn't just represent his double-life-betrayal, but includes a trait of his. Intuition and sensitivity.

Sentinel's intuition helped him quite a bit in the movie. He directed Airachnid to capture D-16 between him and Orion, knowing D was a greater threat to him. It also takes intuition (and a truck load of balls) to make a deal with the Quintessons-- which I'm sure no one would have done unless they were certain the Quints were more likely to win the war. He took his chance when he saw it, and didn't settle for life going back to normal for him once the war was over.

Oh and sensitivity: Sentinel is very vain and prideful, which means he doesn't take being insulted or opposed easily. Cut to him scarring D for life in the throne room :p

He also put a lot of effort into making the citizens of Iacon ADORE him, not just accept him as their leader. On one hand it can be because he wanted to 'live like a king', but I think he also wanted no room for anyone to doubt his ability to rule Iacon as just one Prime. Plus, it's not like he matches the imposing heights of the real Primes. Including Micronus, LOL.

Super serious question:

What kind of cutie marck (my little pony trait) would Sentinel Prime from Transformers One have?

It's for a task, I swear
