I remember reading this comic as a kid but I can never remember the name. I remember the main character was yellow, cybernetic of some sort, and was able to morph. He had a blue suit maybe? In the comic I read there was a part in which the mc shifted through a grave and checked out the bones or something. In another page he morphs into a rocket. I don’t know if it was marvel or dc. If anyone has any info on anything similar it would be greatly appreciated! TIA
