The Living Tribunal can be frightening

 The cosmic abstracts/entities in Marvel typically tend to be aloof and somewhat unconcerned about mortal reactions to them.  Sometimes they can be quite benevolent and key mortals in to why they are around, even helping them make sense of their lives, something most of us would want from a god.  Many times, however, they go beyond the usual treating us like ants and go as far as expressing hostility, just because their day got interrupted by something supposedly beneath their notice.  

The Living Tribunal is basically the Justice of God (in DC, the equivalent being would likely be the Spectre).  As we can see above from his brief time showing up during the events of the Infinity Gauntlet, he considers himself a part of the natural balance and above even the likes of Eternity.  Despite Thanos having iced a half of the universe, LT judges the event based on a notion of created beings doing what created beings do, and nopes out of the whole affair in what could easily be interpreted as a dick move.  All that said, he usually looks rather statuesque when being judgy.

Here he is in Storm vol. 5 no. 5 (this year back in February, a rather epic in scale issue that I will review later), being serenely statuesque and mildly annoyed that Eternity and Oblivion are bringing him a universal conflict to judge over.  You would think that a conflict brewing over millions, nay, billions of years over where to house Death would earn more than just a passing "sigh" from the LT.  I suppose he always has a lot on his/whatever mind, being directly responsible for the multiverse, or at least a multiversal cluster, under the One Above All, but my point here is not to defend LT but rather to point out that he usually looks very chill.  

Not so much in his first full appearance, Strange Tales no. 158, as drawn by the Mother of Cosmic Marvel, Marie Severin (also more on her later).

Glowing things tend to take on a new level of ferocity or aggression when they turn red, if only from looking just a bit more menacing, especially under that little purple hood thing he has on which shrouds his lovely golden face in DARKNESS.  Darkness equals bad in Cosmic Marvel, being the home of things like Oblivion, Knull... you get the picture.  Marie's art there is simple, but rather brilliant in how it can draw in the viewer with a bit of contemplative terror, much like being uncomfortably high while in a room full of Rothko red paintings.  

It gets a bit worse when you see him in motion, complete with those geometric edges rather than smooth hands.  Keep in mind that LT here was ready to throw down and pretty much end the planet because Strange felt compelled to tap into the power of Zom, one of those nasty extra-dimensional demons that makes even our Judgy McOscar statue take notice.  Long story short, that is NOT a face you want to see on the grand cosmic judge.
