20XX, moments before humans could travel amongst the stars, Jerry was created the first mechanical being that can think, feel, and act on his own accord. After the successful demonstration of Jerry capabilities, the US army (At the time) wanted to make a weaponized version of that very same Jerry unit.

Multiple models were made in order to fill in the criteria, but 9 times out of 10 it would fail horribly... 

then the year 2XXX came along and with it, more robots worth similar programming as Jerry and humanity can now travel to different planets commercially. During that time, The US army made significant progress with Project "AXEL", and decided to stick with a completely different body structure from jerry's original design. Since airborne and spaceborne travel was a big deal the team decided to implement a Versatile All-Perouse Aerodynamic Propulsion system (V.A.P.A.P. for short.)

To test this, they first conducted test flight on earth. This is when Axel first gained consciousness.

He's basically a bounty hunter on mars. He's very nonchalant and is usually pretty chill. He has no knowledge on how he gained his skills, but he adapts to them whenever he needs to.

For vocal range, go for something mid to high, a bit nasally/dorky.
