Which dc villain has the highest intelligence rating?

The two sources supplied discuss the DC franchise in general and the 2021 film "The Suicide Squad." Neither source lists or references any intelligence ratings for specific DC villains. Consequently, based on the verified information available, it is not possible to state which DC villain has the highest intelligence rating. To determine such a ranking would require additional data from reliable DC Comics publications, creator interviews, or reputable fan databases that explicitly rank villains by intellect.
