Does Thunderbolts*’ Sentry Actually Have A Long History In The MCU?

As upcoming Marvel movies and TV shows continue to come down the pipeline, new characters are being introduced into the Marvel Cinematic Universe.

While yet to be officially confirmed, it seems very likely that Bob is actually Robert Reynolds – the ultra-powerful superhuman known as Sentry.

As mentioned, that wouldn’t be too dissimilar from Bucky Barnes’ HYDRA missions, which took place between Captain America: The First Avenger and The Winter Soldier.
