Even lower end stuff puts them at 100+ teratons with a punch. That is not even getting to Sani who's dream is to reflect a planet sized meteor (Forshadowing) I will never understand why people make battles with One Piece and Toriko like they are close in power, potential city or island level<<<<<<<country level. Screw Coco's hell poison; he one-shots eveyone on team one piece with a Hell spear that moves near light-speed, much faster than anyone in One Piece
Coco's mold spear move at close the speed of light. What I'm going with here is a relativistic KE calc.
Going to use the 2kg figure here.
Plugging in a 90% lightspeed guesstimation and the weight into this:
I get 2.442E+17 joules as the final number. Which is about 55 megatons.
Insane numbers here, given that Coco is offensively the least powerful of the kings, and that he's surpassing the yield of a Tsar Bomba, but has all that energy concentrated on a spear tip.
