Hey, lets make a rambling post full of fond memories that no body else cares about.
One of my favorite early characters (as in when I would spend hours lying on my trampoline thinking of and then and drawing super hero comics.All of this was in primary school,) was a guy called rubber man who was invulnerable to everything but super heated things as he wasn't vulcanised. He took what would be considered double knockback in Hero Terms and he also had on attacks and also had stretching no concious control.
He was considered the team's Cypher because compared to the other characters his powers were incredibly useless. Especially since 3 of the other characters had forms of invulnerability plus their regular powers. But I just loved his cynical nature and quiet desperation to be more useful. To this end he was given a gun that shot entangles, low power lazers etc. He also became a great pilot.
Eventually I killed him off in a death trap situation that misfired and just powered up all the heroes trapped in it. The other heroes noticed that Rubber man had turned into a black goo and avenged him, they ended up crashing (into the ocean) the space station that they were on, which was the teams until Atmosfear and the Black Battalion (the villains,) stole it.
Years later I missed Rubber Man so much that I retconned the space station crash and death trap so that he hadn't actually died, but had just transformed into a perfectly malleable man who then got amnesia and had been wandering the middle east for years. Malleable Man became his new codename once he got his memory back.
Its interesting how much love you can have for something that you created when you were a kid... It's also interesting how blind you can be to your lame concepts. "No, I swear, a super hero called Layzor would rule! Everyone would love him."
