First Appearances Disclaimer

First appearances are often a "hot topic" among the comic book community. 1st full appearances and cameos are often debated. Due to the comic book industry not having a uniform set of requirements for a first full appearances vs. a Cameo, we are not going to differentiate between the two. A cameo is still a first appearance by definition. When we list a first appearance, we will not differentiate between full vs. cameo. 
First Appearance = becoming visible or noticeable before all others in time or order
