Someone shared this Hunter and Omega piece on Discord today and I had to have it on my blog.
Artist is CatDoesArts on Twitter.
I cannot believe it didn't dawn on me before...
When Clone Force 99 is first introduced, they save Echo from imprisonment and experimentation on Skako Minor.
In the Bad Batch series finale, Echo saves Clone Force 99 (or what remains of it 💔) from imprisonment and experimentation on Tantiss.
The cavalry first saved Echo; now, he's saving the cavalry.
(If we want to take it one step further: in the series premiere, the cavalry returns to Kamino to save Omega. Now, in the series finale, Omega helps save them.)
Also, I find it rather poetic that, after years of Clone Force 99 being rejected and shunned by the regs, it's regs who agree to help free them from Tantiss.
