<p>In Action Comics 23 :
</p><p>"Magic is something that often counters Superman's natural abilities. Spells often trump the difference between red and yellow suns that are the source of his powers"
</p><p>Is this why he's unable to avoid magic attacks, spells counter his speed advantage, in the same way under a red sun he has no super powers?
