Different behavior where he does not kill you instantly when you look at him from too far of a distance; looking at him from a far distance for a longer time should make him teleport closer to you.
Aggro bricks/events that attract him
A behavior where he messes with your sanity
Renamed sound files that are more specific (Such as the beep sound)
I second each of these ideas. But, for the first one, there really should be an option for it.
An option to make him tall or not
Nobody would use that option on their server because it makes Renderman look more like a reskinned Blockhead. Also, without him being tall you can troll people by editing your own avatar. Well, you can do that anyway, but without something distinctive it's easier to troll.
Completely removed Minecraft sounds
I just hope you mean we should use original sounds and you don't mean any offense to Minecraft.
More mysteriousness
He's already mysterious enough, any more "mysteriousness" will ruin it.
I would suggest that Renderman should have a "sanity drain" around a radius - if he's behind you, you will still not be safe even by not looking, this way. It also helps for anti-camping, if anything.
This radius, however, should be in effect only if it would be possible for Render to see the player at that position (fire a ray from player to Render and see if it hits).
On harder difficulty setting, this radius ignores visibility and is bigger/drain is stronger.
Pretty cool idea, huh?
