10 Characters Fans Want In The MCU (And How They Can Be Introduced)
4. Sentry
Sentry is possibly one of Marvel's most complex and interesting heroes in the comics and one that would make a fascinating inclusion to the MCU.
Sentry was made after a meth addict found a discarded attempt at a Super Soldier Serum and took it in an attempt to get high. He developed extraordinary powers of strength, solar energy projection, flight and durability. However, his poor mental health manifested into his own worst enemy, The Void.
Sentry's origin would have to be altered from the comics, but it could possibly tie in with Captain Marvel and her sequel coming in 2022. Sentry and Captain Marvel have similar powers (flight, energy projection and strength), so his introduction would be a good match for Carol Danvers.
Instead of Sentry being created from a failed attempt at Captain America's Super Soldier Serum, it could have been a failed way of replicating Captain Marvel. Either way, with the next big bad not announced for the future of the MCU, the Avengers could use another powerhouse on their team.
