Bro, don't worry about Terry, he's about 95% done.
Mnnngh... I'd say more along the lines of mid-upper 60%/possibly lower 70%. I'll put this here just in case you or anyone else decides to finish him:
-I don't remember Power Geyser ever being a QCFx2 motion in any game. The DP Rising Tackle I can live with, though Power Geyser cmd change just doesn't feel right.
-Clsns are kinda meh. Lacks synergy and most importantly, priority. As basically all of his red clsns are encased in blue ones.
-No side switch for K throw.
-Helpers(special and super) don't stay alive for MUGEN hit registry. Projectiles are limited wrong, hindering Terry when it comes to spam battles, as he has to wait for the prior helper to destroy itself before being allowed to throw another. He should be able to throw another P.Wave when a prior P.Wave is in it's hit anim.
-(EX)P.Dunk should have some invul on startup
-Because you added an additional hit to MK/HK C.Shoot and it doesn't knock p2 down like the EX version, it leaves Terry at positive frame adv for them.(+6/+7) Enough to easily string in a cr.LP and chain to cr.HP then perform another MK/HK C.Shoot for an easy infinite:

-R.Tackle(All) causes debug flood as you can see in the above pic.
-P.Geyser helper and all other super helpers are done wrong. They don't have blue clsns and can't stop normal projectiles:

-There's some errors with his CS in various frame. I can't remember exactly which ones... I think Far s.MK has one of his shoes colored green, while Far s.HK has a randomly misplaced pixel under his kicking leg. I saw a few more as well, put can't remember. If I feel like it later, I'll prolly point em out.
-EX versions of specials feel uninspired and not very useful. Especially EX B.Knuckle. He propels out too far, along with the somewhat excessive cooldown for it makes it impractical to follow up successfully from wall bouncing p2. It also seems that in terms of normals/specials, you can only follow this up with R.Tackle. I'd advise looking over Sander71113's Terry for inspiration with EX moves execution and utility. I feel he handled that VERY well and if I were to make Terry, I would have taken notes from Sander's Terry myself.
-Although subtle, the anim you're using for Lv1 P.Geyser nerfs the atk range of the move. As it's the wrong anim, closer to him.
-Why does the screenbound for T.Geyser, but allows horizontal scrolling? Looks and feels weird as when p2 flies back from being hit, it pulls Terry along with them across the stage.
-Double startup step sound on running startup.
That's about it for now. I'll update this post with new findings, if I find any.
