[Marvel] Why is Galactus humanoid, in armor, and muscular?

He looks like some normal supervillain on earth, in a costume.

He has armor on but he will never encounter anyone to defend against physically. 

He's jacked, but just sits in space all day.

He's not. That's just how he appears to you, because it's easier for your mind to be afraid and in awe of a 40 foot tall jacked dude in purple cosmic tech armor.

And if that doesn't have the suitable effect, the crust of your planet cracking soon after usually cements the desired response.
