Ok.From Marvel's description of the Sentry's power and some things that I have seen and read,I'm willing to bet that the Sentry is capable of alot more than he's been shown to do.Marvel claims that A Sentry with a stable mind has unlimited potential.Most people believe that to be false.From what I can tell though the Sentry's mind has not been stable since whe first found out he existed.Most people still believe though that because the Sentry claimed that he gave World War Hulk all he had and lost that he doesn't have anymore power than that.I wish to prove you all wrong.
This is The Sentry's wikipedia,marvel.com,marvel database and comicvine links.These sources are known for being inaccurate but some cite the comics from which it got it's information from.Please read all the powers that The Senty\The Void posses.For the record,I believe that for the Sentry "stable mind" means getting control of the Void.Classic Sentry has been seen in flash backs using psychic attacks to subdue his enemies...The Sentry has not used telepathy since he "killed" the Void.
According to the OHOMTU...The Sentry's mind has never been stable.He was schizophrenic even before becoming the Sentry.When he took the experimental super soldier serum his mind sub-consiously created the Void.Both beings just as powerul.Robert Reynolds also created a heroic persona,the Sentry to balance out the evil and be the hero.Read his powers..The handbook claims that when his mind is stable the potential for virtually limitless power.Also remeber that the only reason The Sentry's first appearence was not to long ago was because he made the world forget he existed.
Here are some feats and other scans that will prove my theory.
First,here is the fight between The Sentry and the Hulk.
Here is a scan of Classic Sentry.Spider-man refers to him as..."the same Sentry that fought Galactus to a stand still".
The Sentry makes his own Canyon.
Reed Richards claims the Sentry is the "most powerful human in the universe"
The Sentry reduces Absorbing Man to nothing.
Subconsiously as the Void,The Sentry lays waste to the Avengers,Notice that not only is the Void changing form at will...Sue Storm,Dr.Strange,and Iron Man are combining their forcefields to keep everyone safe creating a "super forcefield".
The Sentry rips off Ultron's head...previous incarnations of Ultron were made out of adamantium.I'm not sure what this is made out of,but this is still better than what any of the other Avengers were able to do.The Sentry also pummels Ultron creating a shockwave.
The Sentry brings his wife back from the dead.
The Sentry breaks Doom's forcefield which is believed to be unbreakable and the bands of Cyttorak.Also rips Doom's armor off.
The Sentry Teleports.
Subdues the Hulk with Telepathy
Does Hulk dirty with the Void.Noticed how Hulk is curled up like a baby.
Basically what I'm trying to show you is the Void and the Sentry are parts of the same whole.In order for the Sentry to increase his strength and powers he needs to have total control of the Void which he hasn't been able to do since he created him.As shown above classic Sentry who had a little more control over the Void and he was able to do different things with his powers.He was actually able to use his telepathy at will,which he hasn't used since he appeared in New Avengers.The two times that the Sentry fights the Void it matched strength with the Sentry,so I believe that if the Senty was to become one with the Void the immense strength and powers they both have would combine to make an even more powerful Sentry able to do feats far above what has been seen.
