Devan's Robot (Superbot or something): Meh. Nice idea. Like how he dies, but too easy, and it gets buggy when you place more then one of them. The bug where he stands on one place shooting at nothing while you stomp on him makes him a pushover.

Queen: Original. Was a bit hard at first. But I don't like her ;d. She doesn't fit into a lot of tilesets and takes too long to defeat, even though most her attacks are weak (yell does barely anything, bricks can be easily avoided/stomped)

Schwartzenerdude: Nice, all around boss imo. Might be a bit too easy if you just place him normally, but you could come up with a lot of spiffy stuff with him, and he fits in a lot of sets/stories because he's like a turtle general.

Uterus: Also good, all around boss. Loses the spinning things when jj2 is low on animations or whatever, and I like how he dies as well. I like him around the same as the boss above, maybe a bit less.

Bolly: hahaha this boss was a nightmare for me when I first played, almost as hard as devan. He has a few nice attacks, and I like how you can destroy parts of his ship. Prolly my favorite boss, looks cool too.

Devil Devan: Also pretty hard, although that bug where you shot him when he was in his demon form that made him die automatically made it easier. Don't like him as much as Bolly, around as much as Uterus. Also, that bug where his head sometimes turns into something in the level (Saw his head appear as Eva's in cartoon episode, some sign post in the Demon Invasion, and a CATERPILLAR HEAD in my own pack >|. Also can jump out of the level at times.

Bubba: Another nice all around boss. Tornado attack, jumps around, shoots fireballs. Only problem is that he sometimes jumps out of the level, although I've heard there is a way to fix that.

Bilsy: Moderately difficult boss, was really hard for me. Powerful attacks, teleportation etc. This guy packs a punch. Close race between him and Bolly (but Bolly > Bilsy)

Rocket turtle: I once got this to work. It made a demented turtle with a jetpack or something stand there and do nothing, then suddenly hurt me and dissapear or something. ;o ;o ;o.

Tweedle: Might've looked interesting in Psych or something. Wonder what his attacks were suppose to be.
