Saitama Complex 

Having so much godly power that you just don't care anymore. Fighting the most powerful beings is boringly easy and you don't care enough to give them a fighting chance. You just want it to be over.

"Abby has such a Saitama Complex when she plays Skyrim. She just doesn't give a shit."

Saitama syndrome 

When you've become so overwhelmingly powerful that you lose all interest in competing. Frequently used in competitive gaming.

Named after Saitama from One Punch Man who got bored finishing every fight after just one punch.

Serral has dominated in StarCraft 2 for so long, he must be suffering from Saitama syndrome.
