People want 2-Face in the game. What does he do? He has a pistol, maybe some grenades or a Tommy Gun? 2 Face isn't much in the way of martial arts, he's an every day person.
Joker wouldn't hang much higher on that list without various planned traps & gadgets. Nor GL without his ring.
Though truthfully, I'm not really wanting to debate whether or not a character could conceivably fight without their primary tool set, or to put down the requests for those characters, or even, what said character is reduced to outside of costume. As Inj is a fighting game, it's up to the imagination of those involved to make it work.
Honestly, Round-1-Start. Scarecrow could be absolutely bottom tier with a move set revolving around the use of Fear Toxin that amplifies his attributes (higher damage, damage resistance, other special moves, reversing inputs etc) So that the whole point of using him is finding ways to poison the opponent to get access to better tools. Something along the lines of Bo's Drunken Master variation, or again, Valentine from Skullgirls.
After all, that's ultimately the point of the Scarecrow character. He's an ordinary man in a costume, but also a mastermind. That's why he is always creating stronger versions of his Fear Toxin. Batman (and others) eventually find a cure for it, but then he just makes a different/stronger version. One dose of it and he becomes far more of a threat.
The creative approach with the character, especially being built around status effects/stacking effects is vast enough to warrant exploration in my opinion.
