we dont know if bane will be the strongest yet.
what i do know is in that book he pulled a moon out of orbit to get it much closer to the planet so he could cross it in his flying beast
we will find out when this bookcomes out
and zephiel7, that source from wiki is 100% true because they took it from the new essential guides to characters,
