#5 Curtis Axel - Could be a part of RETRIBUTION

One Superstar who was unsurprisingly released earlier this year was Curtis Axel. Axel, the son of the legendary Mr. Perfect, was with WWE for over a decade, but was only a mid-card/lower mid-card Superstar. The former Intercontinental and WWE RAW Tag Team champion was a part of the B-Team in the final few years of his WWE stint, and teamed up with Bo Dallas. If RETRIBUTION eventually do wrestle, a solid worker like Axel could make them look good.
Axel hasn't signed or made an appearance for any other promotion, which means that he could potentially still return to WWE and join RETRIBUTION.

#4 Mike and Maria Kanellis - Won't be a part of RETRIBUTION
Like a few other Superstars that were released by WWE earlier this year, Mike and Maria Kanellis were unhappy at how they were let go by the company. Their public criticism of WWE rules out a return for them and their addition to RETRIBUTION.
Following their release, Mike revealed that WWE did not support him during his personal battles, while Maria too has been critical of WWE.
Maria once again criticized WWE recently by revealing that WWE "doesn't want to build new stars".
