Common cliches in these comics include:
1. Using sprites from Megaman 7
2. Megaman being a total idiot who loves ice cream
3. Bass being even stupider
4. Protoman being a total badass who's more intelligent than Megaman and Bass combined
5. The "author" being a recoloring of Megaman's sprite from Megaman 7 without his helmet
6. Every character (or many of them) being out to destroy the author
There are many of them out on the web, and most of them use the same jokes to make them funny, but many are also quite original and very enjoyable.
