Pridak comes with two, but my acute senses of perception inform me that you're even less likely to tear into him... Other than that, black Rahkshi legs come in Nivawk and Roodaka, though nowhere else...

Though I agree, Mantax's uneven arms are odd... Especially since it results in "Piraka syndrome" in his left arm because his elbow can't turn properly...

Yeah, my brother and I have all six Barraki, and your acute senses of perception serve you well.

That's okay -- my brother found a mysterious extra one in his Roodaka box. Mantax looks much better now. Thankees!
