>>8811438Mr Terrific has 3 figures to his name as far as I know. The best of the three (in terms of poa) is the DCUC one. The other one is a DCD figure from the mid 2000's with only 10 to 12 poa. The third option is a rare and pricey JLU figure with 5 poa. I believe theres also an infinite crisis figure of terrific but that line is as pricey and hard to find as it gets, so theres not much point in mentioning it.
Similarly Deathstroke has a few options, but the best you'll find are either the pricey DCUC fig or the latest Mcfarlane one. The rest are mostly DCD offerings with god tier sculpts but little in the ways of articulation.
With that in mind, Hoechlin Superman doesnt have much if anything in the way of merch. You'll have to wait on that one. Beastboy has a few dozen figures, alot of them are decent. The mattel multiverse one is the most recent, has plenty of articulation, and is also still being discounted on amazon. The older dcuc release is kind of rare and pricey, and unfortunately, somewhat fragile. But DC direct made more than a dozen different beast boys to make up for it so look into those too.
The bad news I have for you is that the bulk of the TT characters you listed are pretty erratic in terms of figures. Starfire has a few, mostly DCD figures, one crappy DCUC figure, and a handful of bandai figures. The ones based on the 05 animated series are total dog shit. The same stands to be said for both Terra and Raven. All the dcuc releases for these three are as bad as it gets, and the DCD stuff is directly based on the 70s comics.
Tdlr; your options are slim, and most of them suck ass in one way or another. You might aswell buy the ttg merch.
