Yeah, I guess everyone in the Sentry's entire miniseries were all telling Paul Bunyan-esque tales about a character that Marvel thought was so powerful that they retconned their entire history just for him.
As of right now Sentry has no feats better than Thor or even equal to anyway. Sentry stalemated Galactus, so what Thor sent him packing and even Galactus said so. Thor's defeated ego, he's absorbed energy equal to the sun, in fact he made a living sun out of the energy. that should put the whole "fling into the sun" deal. Thor could put sentry away.
Thanks. Thor has also cracked a celestials armor, lifted the midgard serpant, smashed planetoids, screwed with time, ect. Useing the sun for a trash can is a easily produced feat by many characters and not at all impressive to me.
The Sentry's abilities derive from an experimental serum that creates a phase-shift in his molecules, causing each atom to step an instant ahead of the current time line. The serum induces a photosynthetic reaction, resulting in a hyper state of consciousness. Though most of his powers and their limits are still unknown, examples he has demonstrated so far are super-strength, super-speed, invulnerability, and flight.
The Sentry can also project energy fields, control light, and has vast psychic and mental forces mainly used for holding his physical powers together, though it is not yet known whether the Sentry can use them the way Professor X and other psychics use theirs; the only psychic abilities he had displayed so far is implanting his memories inside Paul Jenkins' mind and calming the fury of the Hulk.
It may be theorized that the Sentry also has the ability to produce hard-light constructs similar to those of Dazzler's when it was revealed that the Void is a just an expression of his repressed persona, and thus his creation. With the people dubbing The Sentry as the world's most powerful superhero, and with the serum causing a photosynthetic reaction to his body, completely altering his state of consciousness, it is nonetheless conceivable that Sentry's powers are limitless, and may even rival those of the Silver Surfer's and Phoenix's. In effect, the Sentry's powers are seemingly limitless.
Empowered by the enigmatic Professor's secret formula, high school student Robert Reynolds became a superhuman. After trouncing the school bully who had tormented him, Reynolds sewed together a costume and made his debut as the heroic Sentry. One of very few super heroes active during the years just prior to the Fantastic Four's emergence, Sentry gained new importance when the new wave of heroes rose to prominence. Almost instantly deducing Spider-Man's secret identity, Sentry became a role model for the young hero, as well as an ally to the X-Men, an equal to Reed Richards and a friend to the outcast Hulk. The Sentry even battled Dr. Doom alongside the Fantastic Four and defeated his greatest enemy, the General, with the X-Men's aid.
