Two that come to mind:

1)
Wolverine's Rude Awakening Extreme from X-Men Legends 2.

Its opening level of 10% of your max health restored usually means you'll be immediately killed again shortly after resurrection.

It doesn't work if you die falling off a cliff.

They should have made it a passive skill that would in effect as long as there was at least one other character active in the team.

2)
Many of the weapons from Deus Ex :Human Revolution are only useful in certain circumstances that you're not going to know where the ideal situation is on a first playthrough.

The crossbow and rocket launcher are great in specific locations, and the lack of ammo for the powerful grenade launcher makes it practically useless.
