This basically proves what I've been saying. In order to overcome yellow, you have to recognize the fear behind it and face it. What does that mean? Well, that means if Magneto covered himself in a yellow forcefield it wouldn't work because a powerful GL could still overcome it. So that's not a viable strategy. However, you can't face and overcome something you're unprepared for and strikes you suddenly. Being suddenly enveloped in yellow microwaves isn't subject to overcoming...you just die.
So the Mongul scan means nothing. Mongul is coated in yellow...it was easy for Hal to see it, overcome it and take advantage of it.
A lightspeed yellow lightray? Not so much! 😆
