I thought I would make a list
EE trigger happy golden Yamato blast-1920
Cuckoo clocker evolved, 1800?
Bash(any) charged tail attack, 960
Knightmare gifts keep giving, can go on forever

Close this if its not needed,

: Skull Dash attack 900+
: fully charged Sonic Slam attack 700
S2: Skull Budy 540 I think
: fully charged Boiling 400
: Supernova Blackhole 400

That's all I know

I think it sucks that damage numbers can go this high. Way too much difference in damage between characters.

Although Wallops Tantrum Mode (maximum upgrades) only does 80 per hit, it can hit fast, about 2-5 hits per second with no charge, and easy to hit with. So I think that's the most powerful attack, Kaos' Undead Spell being the second most powerful (720 damage, no charge, easy to hit with).

I strongly hope the strongest core Skylanders get to have reposes.

: Skull Dash attack 900+

Did you test this out against a training dummy? Because I don't think it does that much damage to a normal enemy.

Anyway, I like trying to find Skylanders who do the most possible damage in the shortest time frame, so I think I can contribute here. Be warned that some damage estimates may be off however, especially for the ones that hit more than once in a very short time frame;

Most efficient:

Tantrum Thrower Wallop: Approx. 440 damage in 2 seconds(Hold Attack 1)
Pook Blade Saint Stealth Elf(Non-Eon's Elite): Approx. 100 damage in less than 1 second(with Attack 1, Attack 1, HOLD Attack 3 combo)
Mad Scientist Pop Fizz: Approx. 500 damage in 3 seconds(with burning/exploding puddle of acid)
Blaze Dragon Sunburn: Approx. 500 damage in 3 seconds(Hold Attack 1)
Granite Dragon Bash: Approx. 960 damage in 3 seconds(Hold Attack 1. However, you cannot move while doing so.)
Tempest Dragon Whirlwind(Non-Eon's Elite): Approx 225 damage in 1 second(Tempest Matrix)
Evolved Tae Kwon Crow: Approx 950 damage in 2-3 seconds(press Attack 1 three times)

Kind of efficient:
Axe Avenger Bushwhack: Approx. 1,000 damage in 6 seconds(with Attack 1, Attack 1, HOLD Attack 2 combo)
Evolved Cuckoo Clocker: Approx. 1,650+ damage in 7 seconds(Hold Attack 1. However, you cannot move while doing so.)
Evolved Chill Bill: Approx. 1,100 damage in 5 seconds(Hold Attack 1, must completely freeze. Does not affect bosses, tall opponents, or moderately tall opponents)

Like OP said, Elite Trigger Happy has the strongest one-hit damage with 1920, which can be increased to 8064 if you do a critical hit + holding a Superball in an Arena + being buffed by Rage Mage. And Knight Mare Gift Keeps on Giving stacks infinitely but you will never see so much damage on an actual enemy.
