The jet mode reminds me of G1 Thunderwing. I find the name interesting too.

When I think of (something)-rage I think of someone having a temper tantrum over that something, like game-rage or tennis-rage etc. Perhaps Cloudrage likes to stare at clouds to see if he can see what they look like, but everyone _except_ for him can see stuff! So he gets p***ed off and then goes on a violent destructive rampage. ;D
"Why can everyone see the sailboat but me?!?!!"
P.S.: just read his profile. Interesting to see that he already has a hair-trigger temper. T'would be funny if one of his rage triggers was the inability to interpret shapes in cloud formations. ;D
