Your top 3 favorite Arkham boss battles

Possible spoilers in here. You've been warned.

My three are:

1. Mr. Freeze (Arkham City). This one was clever, particularly on New Game Plus.

2. Firefly (Arkham Origins). It's like Poison Ivy except he's more dodge-y, the bridge makes for a bigger arena, and grappling onto him is plain badass.

3. Killer Croc (Arkham Asylum). OK, so it's not really a boss battle so much as survive the maze, but that's IMO the beauty of it. Croc was a real tough guy in this game, and it made for a memorable experience.

Thoughts?

1. Scarecrow encounter in Asylum

2. Superman in Arkham Knight DLC

3. Deathstroke in Origins

@jarlballin: Hot dog at your 2. I need to play the DLC now.

@foxerdes: I'll be honest, when he overdosed on TN-1 I did not have a good time. At all.

Only gotten up to Origins, which I haven't played yet, but out of the ones I played so far:

1. Mr. Freeze (Arkham City)

2. Solomon Grundy (Arkham City)

3. Poison Ivy (Arkham Asylum)

3. Bane (Arhkam Origins)

2. Ra's al Ghul (Arkham City)

1. Mr. Freeze (Arkham City)
