First reported during San Diego Comic Con, Hasbro put up for a vote, 4 characters to receive the Marvel Legends treatment. The four finalist were selected based on brackets and voting out of San Diego Comic Con 2015, while the final four were voted on by the general public through Marvel.com.
Congratulations to Angela for winning the vote. I am eternally disappointed that it wasn’t Cosmo. I look forward to seeing how awesome the Angela figure comes out though!
