==Overview==
MKLeo's personality is not mentioned, but there is one overarching theme about him: He's really, really good at video games.
* He can memorize his character's name by heart, which is a much bigger deal in DL's universe than in ours https://mobile.twitter.com/DeepLeffen/status/1262764314403852288 
* On game 4, he cannot be beaten by anyone except Leffen who is on game 7 https://mobile.twitter.com/DeepLeffen/status/1247200080987402240 
* He's also good at diddy kong racing, implying his skills go beyond simply smash bros https://mobile.twitter.com/DeepLeffen/status/1246458128054484999
* He's described as top 30 in the world, oddly inspecific https://mobile.twitter.com/DeepLeffen/status/1245739689522446337 
His death and planting into the ground has given evidence towards reincarnation, which has been proved via other sources.
