What the current mob set is lacking is a equivelant to the endermen. Endermen in spacesuits may sound fancy, but I think something more sci-fi in overall nature may work much better than a enderman in a spacesuit. Better yet, being an alien probe it could be easily found on multiple worlds!
So I suggest an alien probe instead.
The alien probe is model-wise like a squid, but its tendrils are a fair amount shorter and much thicker. The probe's around the size of a squid in general. It is a silvery grey color, and has only a single center eye that changes color depending on if it's passive or not. On its sides and lower front, it has various glowy lights on it on the sides, back and front. It is a hovering mob and can actually hover like blazes can.
The alien probe would be found uncommonly in caves of planets, appearing only occassionally and really just passively surveying the place.
They normally have no qualms with the player. However, they may watch the player sometimes at a distance, but aren't hostile...
Unless you get close.
If you get close, it will start making warning noises for a seconds, than turn hostile with its eye turning red. If you back off, it will revert back to normal. It could do this behavior with other hostile mobs, leading to infighting. If a probe in a group turns hostile, all the probes in that same chunk will also turn hostile.
The probe has the base health of a creeper or skeleton, but it also has an energy shield that has eight units of health. This shield is similar in nature to the power suit mod energy shield, but can be beat with magic potions of harm as well for those lacking things that can counter energy shielding. If energy barriers don't make sense or too hard to code, fifteen units of health and ten units of armor is what it has making armor penetrating weapons/potions much more desired.
The probe uses multiple laser arrays taken from the laser fire modes seen with the mining laser from industrial craft 2 in there are two modes; a sweeping laser and a single shot ray. Both of these take a couple seconds to charge which leave sa short window to hide or charge. The single shot ray can actually destroy the block it hits.
The sweeping laser doesn't do much damage, but its sweeping means it can hit you more easily. The single shot laser can kill an unarmored player with full health in one hit on hard. On harder difficulties the probe will start charging its attack again sooner; on the hardest difficulty it will start charging again after a single second of cool down.
The probe has the ability of detecting players through walls like spiders do, and for this reason will use its laser to shoot at you behind walls meaning it can get to you even if you cubby hole inside a 1x2 chamber. The probes stop giving chase if you get more than 16 blocks away from them.
The probe's drop is a small selection of unprocessed ores (1-3) native to the respective world normally, but rarely a piece of alien tech from it like its energy core or one of its tendrils may drop for whatever purposes they could have. Note that in order to keep them from being a renewable source of ores, they spawn rarely and drop rarer ores much more rarely. Not to mention their hovering and block breaking attacks makes it a bit hard to farm them.
