Dreadnoughtus was said to be one of the best titan killers but its health and dmg would be just below enough to solo the titans

It would most likely require 2 of them in the arena to take on the gamma bosses and would be one of the best options for the ice titan

It may not be able to make it to the forest arena easily(unless using cryopods or dino depot mod) and it would be difficult to kill the desert titan due to its only range attack being cannonballs and possibly turrets
