I could see Wally taking out the other two...
But not Bob. The result of the uber super-soldier serum Bob imbibed as a teenager in combination with a "photosynthetic reaction to sunlight which allows to step an instant ahead of the current time-line...". This means speed steal is out on the Sentry. Speed steal is completely ineffective on a guy whose molecules are..."an instant ahead of the current timeline". Re-read the Sentry's '05 mini. I forgot just how powerful the guy is. Broke every bone in Hulk's body as the Void. As the Sentry (which, incidentally, is NOT the real Bob....the Void is Bob...the Sentry is a hard light construct...a projection of Robert Reynolds subconscious...an ultra Jiminy Cricket of sorts....), he literally took out Terrax with one hand, one shotted Attuma and broke through...that's right...I said broke through...Dr Strange's auto shields. Dude's a beast. He re-integrated himself after being de-molecularized by Owen Reese and came back from being BFR'd in time by Morgan LeFay.
Not in a million years does Wally take out the Sentry.
My thoughts exactly.
