Since 2010, Hasbro has its yearly Transformers Hall of Fame ceremony at Botcon (6/27-6/30) that inducts to people that played a part in building the brand, 3 Transformers characters chosen by Hasbro and 1 character chosen by the fans. This year until June 21 you can vote from the below choices for who you think should next enter the Transformers Hall of Fame. To vote, click here.
Ultra Magnus - "If there is any AUTOBOT the DECEPTICONS fear as much as OPTIMUS PRIME, it is ULTRA MAGNUS."
Arcee - "An accomplished, street smart and powerful fighter with little patience for those who don't know their way around a battlefield."
Beast Wars Megatron - "A menacing, hyper-intelligent criminal mastermind who led a group of renegade PREDACONS in search of the Energon they would need to conquer CYBERTRON."
Rodimus/Hot Rod - "RODIMUS is young, naïve, headstrong, and daring when it comes to his own safety in the field."
Prowl - "DECEPTICONS, beware, because PROWL is one tough AUTOBOT out to bring law and order to his enemies."
Personally I voted for Beast Wars Megatron because of the group, he "accomplished" the most of any of the characters between risking all of time and space literally blowing the head off of Optimus Prime and successfully conquering Cybertron. Let us know who you voted for and why in the comments.
