Sagat:

override/pass through moves.

The turn around head butt hits multiple times, and consequently, makes any CC involving this move a lot less damaging.

New Super.
Level 3 kick Super has a bigger hit area.
Sodom: ?
Charlie:
Level 1 Somersault Justice has a lot more frames of invincibility, and travels slightly farther.
His low Jab, even though it can still be rapid-fired, has had its timing changed - it’s slower and thus harder for Charlie to chain more Jabs.
Level 1 - and possibly the other levels of his Crossfire blitz now has a smaller hit area.
Somersault Shell can be blocked in the air.
Sonic Boom travels slightly faster (?)

after a close crouching Roundhouse, a corner Yoga Flame, a Yoga Blast or a standing Jab.
Yoga Legend ‘magic grab’ glitch removed.
Gen:
Punch style now has a very quick but low jump, while his jump in kick mode is very high and slow.
His Gekirou now behaves in a similar way to his SFA3 version; after the initial hit, there is a more time
to follow with more kicks. The Gekirou now also does far less damage during CCs, eliminating his high
damage CC and of course his 100% damage Custom.
Rolento:
All moves performed during a custom combo High Jump now do minimal damage, eliminating his very damaging
CCs.
His taunt now hits.
Standing Jab to crouching Forward link seems easier.
His T+Forward behaves differently.
Zangief:
Level 3 Aerial Russian Slam has new juggling abilities: it will connect after a standing Jab and
one of his mashable throws.
His SPD has been changed so that some of his ticks (low jab-> SPD, knees-> SPD)
and tricks(the SPD can no longer grab opponents on the waking-up) are easier to escape.
His FAB has undergone similar alterations as well.
Champion Edition Zangief:
A common misconception with this character in SFA2, was that his SPD range was greater than the regular Zangief’s. In reality both characters had the same range on their SPD.
However, in SFZ2’/SFA2G, CE Zangief’s SPD reach is far superior (approximately the same range as an
’extended’ Strong SPD in SPD, allowing him to not only grab the opponent from a very far distance,
but he retains SFA2 Zangief’s ability to grab opponent the instant (or near to it) they stand up from a knock-down.
Evil Ryu:
No infinite CC range.
