I feel like El Toro needs a promo also and I think he needs to have a super attack because he only gets a buff power and he is a main story character, also I sort of got disappointed of his second promo in my opinion. Since he is based off of zoro, he has the same look and everything. I thought he looked pretty cool with the black and all but when he got promoted in feel like they took the zoro out from him, I felt like changing my colors to black just so he can look better, I liked the gold color trim but I think instead of both the colors it should be black. That's my opinion, freely disagree but I just like it more zoro style.
Shiruku Nero might get promotion in the future, the producers have actually done some great story development with her hinting at such an occurrence. As for El Tori he's a main character all the way, he will in the future.
