Earlier tonight I saw the most amazing Terry combo ever, and possibly the coolest in the game. (Disclaimer: This is the opinion of a Terry fan.)
I watched a guy do it three times in practice mode, and he had the AI opponent crouching. I'm not sure how necessary this is to the combo, but I wanted to mention it. Also, I'm not certain of the strengths of the moves, so keep in mind that when I saw weak Crack Shoot, it could be strong Crack Shoot. Same for all the others ones. I'm 70% sure of the input, though...

Did you get all that? The spacing looks pretty specific. He began the combo all three times with the opponent close to (about two characters sizes away from) the corner. And crouching, as I mentioned before. Terry does a cross-up jumping D, and does a typical HD combo starter into weak Burn Knuckle. He cancels that into a one-hit Rising Tackle, just to juggle them higher, and then uses a strong Burn Knuckle to pass under his opponent. He then does another Rising Tackle -> Burn Knuckle cancel to pass under his opponent a second time. At this point, they're about mid-screen. Terry does a strong Crack Shoot (three hits) to get his opponent a bit higher in the air, and goes into his Buster Wolf -> Trinity Geyser max cancel. The NeoMax hits the opponent into the corner (the opposite corner they started from) and Terry does another weak Burn Knuckle. I think this is where the spacing becomes incredibly important, since Terry is far enough away from the opponent that only the very end of the Burn Knuckle hits him. This means that Terry recovers quickly enough to add an EX Rising Tackle to the end.
The end result of all that work and all five gauges? 1023 damage. This makes it the first 100% combo for Terry, at least as far as I know.
Impractical? Yes. Awesome? Very yes.
CORRECTIONS: I can't believe it's taken someone so long to mention this, but the first post lists Rising Tackle with kick instead of punch.
UPDATE Kane317: Thank Mr. Kof for
performing the combo for you guys.
