If you’ve seen Multiverse of Madness you know exactly what I am referring to. In the scene where 616 Wanda is confronted by the 838 Illuminati, it has been generally laughed off how the “Smartest Man in the World” Reed Richards attacks Wanda with a limp stretch arm even after watching her seal Black Bolt’s mouth causing his death.
We then see Richards shredded like string cheese.
I pose that this wasn’t a dumb move but one more completely in character for Reed Richards. Richards isn’t attacking an unknown entity. At first when Strange pleads with the Illuminati to release him so he can help stop 616 Wanda, their response is of arrogance. I believe something to the effect of “We can handle your witch” was said.
This was due to 838’s information on the multiverse already led by Dr. Palmer at Baxter. Although the multiverse is relatively new to us in the 616 MCU, my guess is 838 has years and mountains of data on other universes.
Additionally, 838’s Wanda has some powers as we see her levitate back to the gate after 616 stops dreamwalking her, but I pose that because we see basically 0 defense of her children when 616 Wanda invades her home, that she knows she is massively outgunned power wise.
My theory is that most other Wandas are never captured by Hydra and exposed to Loki’s spear. This is the event that charges up her abilities. Most Wandas are very low level mutants with limited powers.
Richards knew all of this and acted abruptly and rashly to try to stop the fight quickly after seeing Black Bolt die. Richards’ problem wasn’t that he was acting dumb, it was that he had a bunch of information telling him Wanda was not powerful.
