Hey,

I just unlocked bethany after defeating the beast as lazarus. I was headed for it lives but since my run ended up being really insane, i decided to go for the beast instead.

Also it states "beat hard mode as lazarus without losing a life" on the character menu, not sure what exactly this means. Either way, in practice this probably comes down to either fighting it lives or the beast, depending on what run you are doing.
