Hype-up Boss

A videogame boss seen on the cover of the game, mentioned in the lore or hyped up when the game released or is releasing, and these bosses end up being the most easiest boss you encounter ever in the game.

These bosses could have the most disturbing lore that sounds like a serial killer documentary, most big ass weapon or is a dead necrotic skeleton king who pulled as many women as he wanted, yet you defeat them on first or second try.
These bosses are usually in souls-borne games such as Elden Ring or Dark Souls.

Person: Damn I just got this game yesterday and I'm almost done with it and the dragon on the games cover uhh what was his name? Oh yeah, it was "Stormslayer" he was very easy bruh. I checked the wiki and this boss had like 3000 HP.
Person2: Goddamn that's a Hype-up Boss
