The ones that cost that much have an AP accelerant for the most part, with a few interesting exceptions. Sorting my roster on “green” and a-z, I see:
Dark Beast: 9ap, does 1244 AOE and converts 4 basic tiles to blue charged
Basic Beast: 9ap, deals 791 AOE and destroys 12 basic tiles conditionally
Beta Ray Bill: 12ap for 4x random hits of 9k, with maybe the best green accelerant in the game after Gladiator Thor
Bolt: 10 green + 5ap on all colors to do a total board wipe and 30k AOE - kind of a next level example but he does have a random tile charger passive as an everything battery to compensate
Grey suit widow 19(!)AP for targeted board destruction and some AOE but on purple she can do 6 targeted green tile placements as a battery
BL4De: 9ap for 4K AOE + self heal
cable: 12ap for ~23k single target that blends out to AOE of it downs the enemy. Has a blue that can charge green for you as a battery
Dazzler: 7ap for 1800 team damage + up to 5240 additional depending on board conditions
Doc Oc 5*: puts out a repeater for 6ap that does damage if matched, and does passive AOE if you sink 18 total AP into it. No battery
Doc Oc 3*: 12ap and does 1541 AOE along with some tile effects, no battery
3* Gamora: 12ap for 1250 aoe and stuns 2 random enemies, no battery
Ghost Rider (johnny Blaze) - 12ap*, does 4179 aoe and creates 2x 459 attack tiles. Costs 1 less for each friend attack tiles on the board to a minimum of 6. Has a red power that creates attack tiles off a repeater as a sort of rollilng discount rather than a battery
Gwenpool: 10ap after matching a unique tile to do up to 3x hits of 6300 - no battery unless there is a Sploits code to add green?
Havok: 12ap to destroy 3 enemy SAP tiles and dealing 2144pts per tile destroyed, followed by 5726 AOE. Has a complex internal battery system that isn’t great in practice but thematically feels like converting engery around. You can spend 9 red to charge 3 blue tiles, then spend 7 blue and pick red to convert 3red ap to green
Ronin: 6ap for 5011 single target damage that will strike again if it deals a finishing blow to the target until it runs out of targets
Hela: 8ap to deal 6799 to the target and 2x hits of 4435 to random enemies, along with a passive to punish the enemy gathering green - deal 4435 to the target and destroy 2 enemy green
4* Torch: 6 green to create a 1-turn repeater that deals 314 damage to a random enemy, and replicates itself every turn up to 5 simultaneous on the board
5* Bobby: 7ap to create 5 2-turn repeaters that deal 2999 random damage, and when matched deal 2481 to the enemy team
Teen Jean: 12a;, deals 5228 aoe and creates up to 4 friendly SAPs, no battery
Jubilee: 9ap to create 4x charge tiles and doing 3389 aoe. battery of debatable efficacy with random tile charging
4* Juggernaut: 0ap green passive that does 420 aoe every time he makes a match. secondary passive that pumps up his match damage making sure he tanks as much as possible
Kamala: 12ap to do 3796 aoe, 8purple AP to convert 7 tiles of a chosen color to green as a battery
Karolina: 8ap deals 3242 to the enemy team, may heal based on board conditions
Knull: 0AP - create a start of turn CD passively that creates a friendly strike every turn, when the CD counts down do 2189 permanent health reduction to the enemy team
Lizard: 7ap deal 2209 aoe; if there are 11 or fewer blue on the board deal an extra 1182 to a random enemy, if there are at least 7 red deal an extra 1182 to a random enemy
Loki 5*: 11ap to create a 3-turn repeater that destroys a random row and deals 6596 damage to the enemy team (destroyed tiles do not deal damage or generate ap) - no battery
Moon Knight: 12ap to deal 18,770 to a random enemy. no battery not AOE, but random targeting has some of the AOE benefits
Nebula: 10ap deal 858 AOE for each special on the board up to 10, no battery
Negasonic: 8ap to do 2203 aoe and create a 6-turn cd that if matched or destroyed will charge a number of tiles equal to the counter. passively will destroy 2x random tiles when you match or destroy a charged tile. she charges tiles left and right, so this power is cheap and has a battery
Quake: 11ap, shuffles the board and does 6664 aoe. No direct battery, but has a 7ap blue that will bust out 8 random tiles of the chosen color for some board shake
Ragnarok: 14ap to do 2747 aoe and 525 self harm along with a random column destruction. Has an 8ap blue that charges green tiles and does burst heal, but this character was subjected to a nerf at some point in antiquity so he is likely deliberately horrible at this point
Red Hulk: 9green for 3692 aoe, or if you have 18 it will drain all green to do 9715. Has a 7 purple battery that drans all enemy green and generates 7 green for the friendly. Once upon a time this was the gold standard in AOE capability. Also has a passive that if he takes 899 or more damage he will create a 1 turn red cd that destroys 6 random basic tiles
4* Rocket: 10ap to create a 3-turn CD that does auto-matches while on the board, and does 10,500 aoe when it goes off, unless it’s matched away, where it will do 8862 offense and 2904 self harm. no battery
Sandman: 9ap, 5382 aoe and stuns the target for 2 turns. no battery
Scorpion: 7ap buff up to 7 friendly strikes, reduce 7 enemy protects, and deal 2432 to the enemy team
Sentry: 12ap to create an X of CDs across the whole board that each do 186 enemy and 65 ally damage. subject of a historical nerf, so not a good benchmark
Spider-Man (peter parker): 10 ap to do up to 6 total random hits of damage (mine is unchamped so i don’t know how much. 1490 at my current level). No direct battery, but for 7 red you can conditionally turn some webs to crits for cascade damage and board shake
5* Lord: 12 green to destroy 3 random columns, leaving friendly tiles, for 8159 aoe. has a yellow battery that converts 5 basics in enemy strongest color to green charged, and does conditional burst heal. Not a great powerset
3* Lord: same as above but does 1/3 the damage. These may be the laziest releases to date?
Super-Skrull: 10ap to destroy random 3x3 block and do 5098 aoe. conditionally does more tile damage that gathers ap
Thanos 3*: 12ap to create a 3-turn cd that does 5214 damage, no battery
Thano5: same as above but does 20,430 damage
Immortal Hulk: 0ap, converts 1 random basic tile to green, then if there are at least 8 on the board, deal 5576 aoe and destroy 2 green to do damage but not generate AP
4* Punisher: 10ap stun allies for 2 turns and deals 3477 aoe + 4515 per downed enemy. no battery
Gladiator Thor: 12ap for 13,432 aoe. at 50% health, destroy 5 basic green/yellow/red (gathers AP) passively - has a battery so good this power is more useful to power other things
2* Thor: 14 green, does AOE and has a red that feeds yellow that feeds green
3* Thor: same as above, does 5333 to the target and 2665 to enemies
Throg: 8ap deals 1720 to the enemy team and converts 5 random basic or enemy SAP to charged tiles. repeats if any enemy tiles are so converted until they aren’t. This character has an excellent coherent design concept
Vulture: 9ap for single target 10450 damage unless airborne, then does that amount as AOE. while airborn generates 4 green, 2 blue, 2 black, 1 red ap per turn
So you can see that costs, damage values, and secondary effects are all over the place based on the state of the game at whatever tier the character was release to play in and when. Recent 4* characters have better green AOE than 5* Loki does - they are cheaper, do more damage immediately, and often have useful secondary effects. Obviously characters like iHulk are hard to compare to, but at the 5* tier sadly that’s who you’re comparing to. By the time Loki will have done 6k AOE one time, your opponent iHulk will have done 40k damage to you passively assuming he is unboosted and you haven’t brought Wanda.
