In Clicker Heroes I normally encounter some strange creeper mostly around the level 110 . Does anyone of you know if there is something special about him or if it's just a picture of someone? Maybe the developer itself?

You've come across the "secret" Kappa boss. From the wiki (go down to the Miscellaneous section):
Secret "Kappa" Boss: When reaching a boss level, there is a chance that instead of spawning the normal boss for that level, it will spawn this "Kappa" boss instead. It is a Turtloid Warlock enemy with the twitch.tv "Kappa" emote on its face.
There's a little more info here about Kappa.
Also important to note is that this boss doesn't give any extra benefit or reward. I'm not sure if it will ever spawn as a primal boss.
