Most hit points for a videogame boss

In the Japanese simulation RPG Makai Shin Trillion (Compile Heart, 2015), players star as a demon lord trying to save their supernatural realm from destruction. In order to prevail triumphant, players must defeat a main boss called Trillion, who has 1 trillion hit points (HP). Hit points (effectively "health") are a common denominator in RPGs. Although figures are entirely relative to a game's own set-up, that number still far exceeds anything that has been seen in rival titles. Makai Shin Trillion was due to be released for PS Vita in July 2015.
