Okay...this is the only time in which Thanos uses the Power Gem by itself. Proof of this:1. http://i184.photobucket.com/albums/x287/Deywos/The_Infinity_Gauntlet_04-09.jpg

Thanos unfreezes time. He's still adjusting to limiting himself, and so gets ambushed. Nevertheless, he blasts Drax away like nothing and the narrator claims they are 'bothersome fleas:'

Thanos isn't even bothering to defend himself from Hulk's shots. Doesn't need to. He's invulnerable. And hey - shows off a neat trick - the ability to grow to enormous size:

(Note the durability when he's taking Vision's blast)
Another neat trick - Thanos trapping Namor and She-Hulk in somekind of rust/fungus/whatever:

Gets hit by Mjolnir unexpectedly. Back up nearly instantly after blowing Doom the hell off of him, and looking Super Saiyan:

More neat tricks by Thanos' Power Gem? Teleportation portals, tossing Thor aside like a baby and swatting Firelord like a fly, then turning Wolverine's adamantium skeleton into rubber:

Unphased by Cyclopes' optic blasts and easily overpowers Scarlet Witch:

Force-blocks and kills Cyclopes before tearing open Vision:

Cloak attempts to trap him in the Dark Dimension, and cannot. He's also laughing off a blast by Drax and apparently thinks Firelord attempting to choke him is humorous:

Opens up a time portal and BFR's Firelord and Drax to the prehistoric age:

Even more exotic stuff - looks like he's getting a beatdown. Then again, he recovers quickly and seems just fine. Then proceeds to turn Thor into glass and Nova into a bunch of blocks.

Shatters Thor, annihilates Quasar and reduces him to ash, transmutes the floor to grab ahold of Captain America's legs, then smashes his shield into pieces with one blow.

Again...all of that was with solely the Power Gem. After nearly having it taken by SS, he wills himself back:

As you know, the Power Gem backs the other gems and amplifies their power, too. Meaning with the Space Gem added to it...
Anywho, he beats PC Supes with just the PG or the PG and SG.
