not always; bigger =/= stronger

its usually the case for phantoms though

Phantom slammers are actually considerably weaker than normal phantoms since they're slower

i interpret strength as it's damage per hit rather than movement speed. a regular phantom is arguably stronger than a king since its faster and can land more hits and you can easily evade the king, but the king phantom packs a stronger blow.

But if a phantom queen is like an ant queen, it's pretty weak, even though she's the largest ant

I think we just need more info

of course theres no way to be sure until aj adds her to an adventure or specifies, but based on the strength and size of other phantoms, it would be mostly reasonable to assume so.

it would be interesting for them to not just be predictable and maybe make the queen less of a fighter and make her maybe a brood queen like an ant.

or maybe she's so massive she can't do proper damage to small animals

it would make for a pretty lame fight if the queen just sat there and did nothing significant/only summoned little phantoms to fight for her. there also doesn't seem to be more than one queen while there are multiple kings, which may mean that she is the "greater" boss of phantoms. I'd like to see aj actually do something with her though.
