A few thoughts on some of the champs.
Ive been re reading lore a lot lately as I have personal interest in knowing more about the champions I and many others play day in and day out. I was curious about a few small things that may or may not have been asked before and so here goes. First off I would like to Pose a question about Shaco and Evelynn now if you read both of their lore's (eve's old lore in this case which I will provide a link to above) you will see some similarities, both champions for instance have unknown origins, are brutal and are assassins (or speculated to be in shaco's case). The question this brings to me is this, Could Shaco and Evelynn be related in origin or have some form of connection to each others origins possibly coming from the same place? now I know old lore hints at eve coming from the shadow isles but that might be only speculation so this could be very wrong but the old lore also stated only that there was some evidence that she came from the shadow isles so it could be possible she wasn't. Again in this theory I could be way off so correct me if i'm being stupid here.
My next question on a smaller not still involving eve is this, The champion comment in her old lore claims eve to be "the ultimate predator" so following this are there any forms of dispute between Rengar and eve or Kha and eve? The reason I ask is Rengar seeks the ultimate pray (namely kha'zix the one that got away and injured him) and kha just wants to consume the best of this world and evolve through it so being named the ultimate predator wouldnt that put a hit on Eve's back from them?
My final question is why do a lot of the void champs seem to revolve around Eating everything and have 2 part weird names? I mean lets just see here Cho'gath, Rek'Sai. Kog'maw. Kha'zix all are champs revolving around devouring/eating things to either evolve in some way or just for the hell of it. Like are those 4 somehow related to each other in ways other than just being from the void and there is some form of deeper connection in the void with all the creatures we have not been notified of or is it just riot making champions while being really hungry?
Well thanks for reading my possibly stupid thoughts, I would like to hear your thoughts on these kind of things as well and uh yeah maybe someone could help clarify for me as well. Thanks again and cheers.
and even 
are mentioned to be very hungry beings and 
seeks knowledge which he gets through disintegrating his targets(thus he more or less consumes it too).It is something that all void creatures share,almost like they are trying to fill a void within themselves;)
As for their names:
It is possible that the void creatures get their names from the desert shurima,where they are known as "outer beasts",in Shurima they also have a type of goat named in a similar way and it lies quite close to the place where all the void creatures come from so it would probably one of the first places where humans encounter the void creatures.And yes all void creatures are named like that,the only void champs who don't have a name like this(Kassadin and Malzahar) aren't from the void,but only get their power from it.
And there is no known connection between the void champs other than the fact that they are from the void,it is however known that malzahar brought kog'maw into runeterra and that kog'maw has a daddy that is probably still in the void.
