Dynamo

Dynamo attacks twice in runs that play enough maverick stages - after 2 mavericks, and after 6. While Dynamo has a higher level and more attacks in the second encounter, he is trivially defeated by Zero in both instances.

Fights with Zero

Assuming a run through all stages where Zero is collecting upgrades, Dynamo is trivially defeated using the Saber Dash Cancel .

Fights with X

Charged Grizzly (using the Fourth Armor), while not the weakness that stuns Dynamo, is very effective.
