[the boys] Shouldn’t there be more super intelligent heroes besides Sage?

A-Train has super speed, so his brain should be operating at a much faster level than normal even when not using super speed.

Tek Knight has enhanced senses so should effect his intelligence.

Gunpowder seems to have a super intuitive advanced sense of physics and geometry in that he can quickly alter the aim of his gun to land ricochet shots. His brain has to be enhanced to do this.

even Homelander himself with his total package powers. Super vision, X-ray vision, he’d need extra hardware to process all that. And his own super speed should increase how fast his brain operates.
