For me, it would have to be Chop Chop's Pod Gauntlet. Man, I hate that sucker, bouncing off the puffer pods and half the time not shooting the poison pods before they explode on you! (Is it just me, or can you only pop them while they're growing? Like once they're full, you have to wait for them to pop themselves?) -Usually with a chompy hanging off your butt while some jerk shoots arrows at you! The only time I've enjoyed that challenge was with Terrafin, just burrowing under everything to get to the keys. I went on a killing spree that time around, and slaughtered every chompy and archer in the place, just to work off some of the resentment!

I hate Voodood's. Each Spell Punk does not deserve its own cutscene. What a waste of time.

Oh yeah, I forgot about that one! "Get the Tech Spell Punk", well DUH! I'm trying, if you'd just let me get on with it! Not to mention if you're using a character that has to use bombs, every now and then they'll go flying off in random directions, taking about three tries to hit. I usually just anvil the heck out of the ones with platforms if I get too frustrated.

Purple
Chompies

The one with the paintings! it's so hard.

Slivers, that one I don't have too much trouble with, apart from Ghost Roaster and some of the fire boys. keeps leaving ghosts behind that zap the purple chompies (still haven't managed it with him), and some of the fire guys leave puddles of flames that of course the purps walk right into! Hey, normally I'm all in favour of suicidal chompies, but in this instance...

Rand OM, the "falling anvils" item from the Empire of Ice pack is your friend there; in fact with some characters it's the only way I could do it! Since most of my Skylanders are upgraded now, I make an attempt first, but if it's clear I've got no chance, it's "Look out below!"

Double Trouble's..

double trubles heroic challenges is onpesebul with eruptor

The one with the paintings and vases your not supposed to destroy.
Drobot and zap could do it at all, they always managed to destroy everything ;

I later bought the ice expansion, got the anvil. Just had to try the mayhem
Wow was I surprised to find it ONLY kills the enemies, not the vases or paintings
Had to use it with several of my skylanders (but those two especially =P )

Also had trouble with the purple chompies. But found the swords to do a great job there. It's a bit tricky, but I usually manage in the first or second go using only the swords =)

Next is the bumping pods, wow is it annoying ::

Double Trouble's

Most annoying is Whirlwind's "Lobs O' Fun" if you don't have a Skylander that can attack the pirates on the platforms without using the bombs. Those bombs seem to go everywhere except at the pirates unless you are VERY careful in how you throw them.

Close runners up:

• Chop Chop's "Pod Gauntlet"
  
• Double Trouble's "You Break It, You Buy It" ... very tough with upgraded Skylanders
  
• Drobot's "Save the Purple Chompies" ... see Double Trouble, although not QUITE as bad
  

Double Trouble
Zap
Drobot
Stealth Elf
Chop Chop
Lightning Rod (not the challenge itself, but getting the challenge to work)

I agree with Himewad. Whirlwind's is VERY annoying. As for Chop Chop's, I feel yah. I use the Healing Elixir if I get low health, but it doesn't help with the rage.

For Double Trouble's, I'll try the challenge once, and if I keep hitting vases or painting, I use the Anvil Rain.

I'd have to agree with Spell Punked as being one of the most annoying... the stupid cutscenes are not needed. That is closely followed by You Break It You Buy It.... not for the challenge, but for the extended showing of the location of all the paintings... all those should be skippable on all platforms. As an FYI, I have done every challenge with every skylander now (PS3), so all CAN be done... only a few gave me some trouble.

the last charm on cinders can be a PITA with slow characters. Been KO'd a couple times on that part

I agree that the paintings/vases one is hard and the pod one is annoying. lobs o fun is a glitch that you cant hit them with the bombs.

Pod Gauntlet is a bit of a pain in the butt, mostly because it's not much fun to navigate all those pods. Dungeoness Creep gets annoying sometimes when you get trapped by the zombies at the end and have to restart.

Purple chompies Drobots challenge (especially if you have leveled up and upgraded attacks), then lightning rod cause I have a 360 and its a glitched challenge.

time twister is very happy in heroic challenges
